well, aren't you up early? we're glad because now we're not here by ourselves. i'm christi paul. >> i'm victor blackwell. this is "new day" saturday. we have a lot going on this morning. you know, this is being called one story we're following, the worst security hole the internet has ever seen. now your most vulnerable information may be at risk. we'll talk about that. >> and have you heard about the president's tax returns? well, they're in. he took a hit in income last year. we're going to talk about that too. >> yeah, making less money. but we're going to start with the search for malaysia airlines flight 370. it's now been 36 days since that

flight vanished. investigators -- good news here -- may be closer than ever to locating that missing jetliner. >> we know right now at least 10 planes and 14 ships are scouring the smallest search zone to date. that's the good news. crews are focused on an area in the indian ocean that's about the size of massachusetts and connecticut combined. you may recall at one point the search zone was about the size of the continental u.s. definitely making progress. >> yes, progress there and a boost of confidence overnight from australian prime minister tony abbott. officials believe four pings detected this week are coming from one of the plane's black boxes. >> there have been numerous, numerous transmissions recorded that gives us the high degree of confidence that this is the black box from the missing flight. what we're now doing, given that

the signal from the black box is rapidly fading, what we are now doing is trying to get as many detections as we can so that we can narrow the search area down to as small an area as possible. >> this comes at a critical time in the search. the batteries on the plane's black boxes are quickly fading, if they're not dead already, in fact. >> but officials warn recovering these black boxes, this is a massive task because those signals are coming from about three miles beneath the surface. >> so let's put this in perspecti perspective. flight 370 is about 200 feet wide, 242 feet long, which means from where those signals are coming from, you'd pass the statue of liberty, the eiffel tour, and the tallest building in the world on the way down to it. >> let's bring in cnn's will ripley. he's in perth, australia.

what's the latest there? >> reporter: yeah, you know, the visual search is wrapping up for the day. you talked about how far we've come, mentioning the size of the search area. at its biggest point, more than 3 million square miles. now we're down to roughly 16,000 square miles. still a large area, but certainly a lot of progress has been made. but we're missing one key piece here. still, 36 days in, we do not have one single piece of physical debris from flight 370. there's also the underwater search, which continues to happen around the clock. that's the listening devices. both the u.s. navy's tow pinger l locator. but it's been more than three days since we've last detected a ping that's suspected to be from an airplane black box. so the question now is going to be when does the search transition from listening to actually physically searching, using the underwater submersible. that's a question we could get

answered this week. but they want to keep listening as long as possible to make absolutely sure that these devices are not emitting anymore pings. >> is this the only place they're searching at this point, will? i mean, there were so many different search areas. three even just as of last weekend. have they ruled out those areas completely at this point? >> reporter: well, we know that the visual search area and then the underwater search area are separated by several hundred mai miles. really, the underwater search area is where they're focused as far as the potential location of these black boxes. they feel even though we don't have any physical evidence that these pings they've detected are solid enough that it's worth devoting a considerable amount of time and energy to that particular area. as far as the visual search area, you know, they've been trying to calculate the currents to track, you know, if the plane went down in a certain spot, where in these 36 days would the debris have floated to? that's what's happening. they feel like they're on to

something but still a lot of work ahead, guys. >> all right. will ripley, thank you so much for the update. we appreciate it. and let's discuss the latest on the investigation with cnn aviation analyst and former inspector general with the u.s. transportation department. >> we have simon boxwell also with us, an oceanographer joining uses from london. mary, i want to start with you. there is this level of optimism because of the comments from prime minister tony abbott saying there's a high degree of confidence, kind of doubling down on these signals. but you've been here in that chair, i've been here as we've heard these optimistic statements from abbott in the past. he said that there's new incredible information that's come to light. that was march 19th. turned out to be nothing. march 22nd, we now have a number of credible leads. turned out to be a dead jelly fish. are we investing too much in the optimism of the prime minister? >> well, in the optimism of the

prime minister, yes. but in the reports of angus houston and the fact they actually have pings, some of them as long as two hours plus, that's pretty good. there have been other accidents. based on other accidents in the past, sometimes they don't have that much to go on and they're still able to get those black boxes. i think there's cause for optimism, but no matter how many pings you get, you still have to have a -- it's long, hard work to get those submersibles down there and actually find the black boxes and figure out where they are and how to get them up. so there's lots to go yet. but the pings are good. >> simon, let me ask you, because i think a lot of people are watching this saying, if you have this narrowed down to, you know, a 15,000, 16,000 square mile radius, which is where we're sitting, why do you not send at this point that blue fin drone to see what it can do? >> if they can identify these

pings and confirm they're real, they're going to keep looking until they're confident things are stop being sent. we're well past the 30-day design limit of the pingers. we might expect to see an extra five, six days, but they are pretty much dead now. so it doesn't mean that if they rely on the ping data, we're not looking at 15,000 miles. we're probably looking at an area about the size of the city of washington. so it's come down a lot more. that becomes feasible. if you're sending one of these aevs down, they're moving very slowly, about 4 miles an hour. they're surveying a very small area. these only may be 50 meters, 100 meters. that will take a long time. so this is why they put so much effort on the pinger first. otherwise, it's just a random deployment. >> so mary, the follow-up to that statement i'm going to bring to you. if over the next 24 hour, 48

hours there is no new ping, and let's say 36 days, the batteries on the pingers have expired. how long do you expect the wait before they will send down the blue fin with whatever area or whatever information they have because they don't expect the batteries to send out another signal? >> oh, i think they're already getting ready to do that. the united states sent a supply ship in, a logistics ship. they're getting stuff on site and ready to go. but remember, it takes a long time to get them ready to go and deploy them. according to the blue fin specs, it can cover 40 square miles a day on mapping, but they might have it go slower than that to get a clear picture on mapping. i think they're preparing to do that based on the logistics ship. again, i caution, there was a crash in the java sea a number

of years ago. it crashed in january. they got the black boxes in august. the world record was in the indian ocean, 16,000 feet. they got those in two days. you never know how long the next step is going to take. >> simon, does it bother you they haven't seen one piece of debris up to this point? >> no, not particularly. i mean, they're looking for surface debris. let's face t over the past month, they've been chasing rainbows. they've been looking in the wrong place. it's only in the last week that the search area is focused on this far north site. far further north than anything before. if we look at the currents in this area, the western australian current takes material further north. they've been looking in the wrong place. satellite data so far has proven to be a red herring. they really do need sightings from ships and aircraft. but this far in, because we're so far past the crash date, to be honest with you, finding

something would confirm it's down there. backtracking from wreckage six weeks on isn't going to give us much information. so the real hope lies in these ping data and getting an auv down. it can cover 40 square miles in a day. that's working shallow. and we're right on the limit of the depth. she's rated to 4,500 meters. we're working at 4.5 kilometers, about 15,000 feet. so everything is right on the limit. it takes time to get the system down there, two or three hours just to get it down to the right depth. then it only gives them about two or three hours on survey before it comes back up. bear in mind, they don't see the data until it comes back to the surface. >> a lot of progress has been made. still a lot of work to do.

mary, simon, thank you both. >> now, at this point in the search of this plane, the tech team on board the ocean shield has one of the most crucial jobs detecting the sounds meant to lead investigators to the flight's black boxes. we're going to show what it takes to pick up a ping. also, another tragic story we're following. several teenagers killed in this fiery bus crash in california. we'll take a closer look at just what went wrong here. vo: once upon a time there was a boy who traveled to a faraway place where castles were houses and valiant knights stood watch for the kingdom was vast and monsters lurked in the deep and the good queen showed the boy it could all be real avo: all of great britain, all in one place book on expedia before april 30th

to as small an area as possible. once that's been done, and i don't want to speculate on when that might be, once that's been done, it's our intention to then deploy the submersible, which will conduct a sonar search of the seabed. based on the search attempt to get a visual on wreckage. >> that's australian prime minister tony abbott. when he says we, that group includes americans. hard-working people who are technically listening for the pings that everyone hopes will continue. >> this is such a monotonous task. it sounds basic and rudimentary when you think about it. but as cnn's brian todd explains, so much can get in the way of just picking up a ping. brian? >> christi and victor, no one knows their names. they spend hours and days in an

isolated, confined space in the middle of the indian ocean, often staring at nothing, listening to silence. but right now, the sonar technicians aboard the ocean shield may have the most important jobs in this entire search effort. we're hanging on what they're hearing. the hopes of finding the black boxes from malaysia airlines flight 370 rests on a few anonymous technicians. >> day and night, there is no break. they're on all the time. what they do is so important to us. >> we went behind the scenes at phoenix international, the company that made the towed pingping er locator. phoenix has nine people on the ocean shield. among them, sonar techs tasked with looking at monitoring, listening, and listening some more. >> you'll sit for days at a time listening for nothing. then you might hear a chirp, but you don't hear another one. until you can duplicate it and run it back at different angles,

only until then are you positive you have it. >> even then, experts say, sound in the ocean can play so many tricks on your ears. >> several people can look at a signal and see different things. because all they're really recording is sound energy. >> false positives from fishing and research equipment left in the area. from debris and thermal conditions. from the vessel itself can also play tricks on the techs. phoenix's operators are good at weeding out false positives. they do it by carefully monitoring the specific frequencies and repetition rate. and at centers off-board, they're highly trained to block out any other potential sounds. paul nelson, who worked the search for air france flight 447 describes the work as meticulous, tedious, time devouring. >> there's two shifts. they work 12-hour shifts. the first crew will work from midnight to noon. the next team will work noon to midnight. you're monitoring the weather. you're watching what's coming as

far as weather. you're monitoring and sitting in front of the screen hoping and praying that you're going to hear something. >> does it drive them a little stir crazy? >> everyone looks forward to the meal time. that breaks up the monotony. >> some of these techs have been doing this for more than 30 years, decades of often thankless dedication just to find that one breakthrough pattern of blips. >> everybody is so focused on this task at hand that once you know you have it, it's a tremendous feeling. that's the high. >> once signals are detected and confirmed, it's reported up the chain of command. top officials make those announcements that we all hear. and the techs simply go back to work with us still not knowing their names. christi and victor? >> all right, brian todd reporting for us. thank you. >> and we're going to talk about something else too. do you realize it's been four years since the death of that trainer at sea world that we all talked about so much? well, since then the shows haven't been the same. and a new court ruling means --

on the search for malaysia airlines flight 370. >> actually, a lot of news coming from the prime minister this morning, who seems to be very confident, saying that four signals detected by a u.s. pinger locator are coming, he says, from one of the plane's black boxes. he's that confident. >> right now at least ten planes, 14 ships are scouring the smallest search zone to date. crews are focused on an area in the indian ocean about the size of massachusetts and connecticut combined. you may recall that at one point the search zone was about the size of the continental u.s. >> but time is ticking away here, obviously, for search crews. the batteries on the plane's black boxes are quickly fading, if they're not dead already. officials warn recovering the black boxes is a massive task. even though those signals were detected within 17 miles of one another, they're coming from about three miles below the surface. >> so let's talk now with someone who knows these pingers likely better than anyone else. >> yeah, chris is the director

of a company which makes that underwater locator pinger that everybody is searching for. he also got to hear and confirm the first set of pings detected by australian search teams. so chris, i know earlier this week you told cnn you were extremely confident the sounds were from the flight's black box. now search teams have reported hearing four pings. is there any doubt in your mind that sound is coming, in fact, from flight 370? >> no, there's no doubt. the acoustic signature of the beacons and the cadence they're coming from is definitely from one of our beacons. so we're very confident that it's from there. it's got a very specific sound. you've got a pulse and a ping once every second. that's not ready found in nature. that's why they're designed to be unique and stand out.

>> so it's day 36 of this search. these batteries on the pingers are required to last 30 days. do you think the batteries have maxed out now? could there possibly be another 24 to 48 hours of battery life left? >> in our testing, we've been able to get anywhere from 35 to 40 days. we were told that the pingers were due to have their batteries replaced last year, which would indicate they're five years old and nearing the end of their life. so we're confident that there may be a couple more days left, but as the battery starts to degrade, the signal is going to get weaker, so it's going to be even more difficult to hear it until it eventually can't produce enough power to send a signal out. so there could be a few more days left. >> there's been a lot of talk, chris, that pingers should have a longer life. how hard is it to create technology to make that happen?

>> well, we've actually created one that has a 90-day life. out of the air france disaster, there was a new tso requirement that new pingers starting next year will have to have the 90-day life. we've created that, and we have it out there. but once it becomes required, the airlines are going to have to put it on there. so there is out there a 90-day beacon. >> so chris, help us understand something. a week ago when the chinese reported hearing a ping, they said it was at 37.5 kilahertz, which is the frequency at which the pings emit the signal. but the australian defense force, the adf, says that the pings that have been detected near the ocean shield were not exactly at 37.5 but within the range. explain that discrepancy, how it can still be so certain these are pings from black boxes but not at 37.5. >> well, you've got a bunch of

reasons. mostly the pressure, temperature, and the salinity of the ocean. the audio sounds are moved around under water and it plays some tricks. it's more important less the frequency, it's more the cadence. it's more the unique manmade sound of it. and it wouldn't be unusual to detect it at a lower frequency, which is the 33. >> hey, chris, let's listen to australian prime minister tony abbott here who continues to afu affirm those pings are starting to fade. >> we're now getting to the stage where the signal from what we are very confident is the black box is starting to fade. and we are hoping to get as much information as we can before the signal finally expires.

>> so if we're at day 36, gosh, i mean, chris, you make these things. how long do you think we have? >> i think we've got maybe a day, possibly two more. knowing how old the batteries were. we've seen them last up to 40 days. they're certified for 30 days. anything after that is, you know, is bonus time, really. >> so with full battery, the search teams ideally come within a mile or two nautical miles to locate this signal. with the batteries die, how much closer do they need to be? does the signal get weaker or does the frequency become -- or the frequency of the signal become less frequent, i guess. >> well, the batteries -- the pingers have a two nautical mile

range when they're actively pinging. as the battery starts to degrade, the frequency will actually get lower and lower and the range will go down. the frequency goes lower because there's a ceramic ring in there that creates the acoustic sound. as it has less and less power, it -- the output goes down. so you'll hear both of those items. and the range could go down until it's inaudible. you know, a mile or less than a half a mile. >> all right. chris, thank you so much for being with us. >> no problem. thank you. >> we appreciate it this morning. so australia's prime minister, as you heard, has really been asserting his true confidence this plane has been located because of these pings. but the malaysian government, they are pretty hesitant. [ male announcer ] this is jim.

a man who doesn't stand still. but jim has afib, atrial fibrillation, an irregular heartbeat not caused by a heart valve problem. that puts jim at a greater risk of stroke. for years, jim's medicine tied him to a monthly trip to the clinic to get his blood tested. but now, with once-a-day xarelto jim's on the move. jim's doctor recommended xarelto. like warfarin, xarelto is proven effective to reduce afib-related stroke risk. but xarelto is the first and only once-a-day prescription blood thinner for patients with afib not caused by a heart valve problem that doesn't require routine blood monitoring. so jim's not tied to that monitoring routine. [ gps ] proceed to the designated route. not today. [ male announcer ] for patients currently well managed on warfarin there is limited information on how xarelto and warfarin compare in reducing the risk of stroke. xarelto is just one pill a day taken with the evening meal. plus, with no known dietary restrictions, jim can eat the healthy foods he likes.

do not stop taking xarelto, rivaroxaban, without talking to the doctor who prescribes it as this may increase the risk of having a stroke. get help right away if you develop any symptoms like bleeding, unusual bruising, or tingling. you may have a higher risk of bleeding if you take xarelto with aspirin products, nsaids, or blood thinners. talk to your doctor before taking xarelto if you have abnormal bleeding. xarelto can cause bleeding, which can be serious and rarely may lead to death. you are likely to bruise more easily on xarelto and it may take longer for bleeding to stop. tell your doctors you are taking xarelto before any planned medical or dental procedures. before starting xarelto, tell your doctor about any conditions such as kidney, liver, or bleeding problems. xarelto is not for patients with artificial heart valves. jim changed his routine. ask your doctor about xarelto. once-a-day xarelto means no regular blood monitoring -- no known dietary restrictions. for more information and savings options, call 1-888-xarelto or visit goxarelto.com.

welcome back. if the search for 370 is zeroing in on the right place, it's a challenge to say the least in that stretch of the indian ocean. and we want to give you some perspective about just how deep we're talking about here. at the very top of this animation, that's sea level. when people go scuba diving for recreation, that go about 130 feet. the entire state building, by comparison, is just over 1200 feet. and the bottom of the grand canyon, just over 5200 feet.

the deepest diving sea mammal gets to more than 9800 feet. even further down, the wreckage of the titanic was found at a depth of 12,500 feet. and the towed pinger locator we've been talking about, which listens for signals from black boxes, that's about 10,000 feet below the surface. the pings that have been picked up from the plane are more than 13,000 feet below the surface. so although australian officials are optimistic they're now looking in the right place, there are challenges when we're talking about these kinds of depths. about three miles down, in darkness, with silt that can be inkr incredibly thick. it's a difficult environment, for sure. it's been said we know more about the surface of the moon than the bottom of the ocean. christi? >> so victor, let's talk about this. as we hear conflicting points of view now on the search for flight 370, australia's prime minister confident that searchers have detected signals from the missing jet.

malays malaysia's transport minister is not so sure. so i want to ask, what is prompting this hesitation from malaysian authorities? >> christi, the malaysian authorities are hesitating because they say until they actually find the black box, they remain cautiously optimistic. have a listen. >> signals need to be verified. i do agree with angus houston that any lead -- and this might be one of the measure cautiously optimistic leads that we have because the signals are similar to a black box. >> the acting transport minister going on to say all of this needs to be verified, and if, in fact, those signals are coming from the black box, then the new

phase, the next phase of this search will begin. that is actually the underwater search. >> you know, sumnina, i think some of the things people can't get out of their heads is what it has been like for these family members. what are they saying about this new information? >> well, the family's reaction here has been overwhelmingly consistent and that is until they actually see the evidence for themselves, until they actually see the debris, they will not believe, they cannot believe their loved ones are no longer alive. we've been talking to a family here, a father and mother who lost their only son. the mother continues to call her son almost every day. she genuinely believes that he is still alive. we just got a message from a mother of the -- one of the iranian passengers. she says that she is still having sleepless nights.

she still can't understand how that plane could have flown for so many hours and no one could have noticed. she says she hopes the americans are still on top of this investigation because she's lost hope in the malaysian authorities. she says she's having a very difficult time believing that he is no longer alive until she actually sees the evidence. >> and who could blame them? anybody who has kids or somebody they love and they don't have any evidence, of course that's where they're going to go. thank you so much. we appreciate it. victor? >> all right, christi. thanks. we've talked a lot about the search for those pings from the black boxes. to find them, we talked about the depth of the water, but the searchers have a lot more deep water to deep with. tom foreman has more. tom, good morning. >> hi, christi. hi, victor. we've been talking a lot about the devices put into the water there to try to locate where these pings are coming from. the towed pinger locator, that's produced four solid hits so far.

there have also been attempts to put in buoys to see if they can listen to anything. but any listening device in the water here is going to face one real challenge out there at least. the challenge is what's called the sound fixing and ranging layer. this is about a half mile down. it's a naturally occurring phenomenon. it's a layer where sound moves less quickly than it does in the ocean below or above it. a lot of different reasons. salinity, water pressure, temperature. but the results are something really to contend with. if sound is coming up here and it hits this line, because this is slower, it can essentially bend that sound and make it go at a very different angle than it was a moment ago. then it may come out where you don't expect it at all. also, in some cases, it may come up, hit the layer, and ping-pong

between the top and bottom. by some theories, particularly with lower sounds, it may go many, many, many miles before it comes out. this may explain why a pinger that shouldn't be heard more than three miles away is being located at a range of some 17 miles. as it's coming up, it's possible that these anomalies, these strange things that happen to sound in deep water are affecting that signal. and they've got to overcome that and crush it down to the actual location before they go under water and start mapping very much. victor, christi? >> wow. it's marine science lesson for all of us. tom foreman, thank you very much. still to come, this is huge. now some big-name websites are coming in to fight this huge problem, rushing to patch a newly discovered security gap. we'll tell you if you're affected and how you can keep your information safe. also, we'll talk more about the technology being deployed. we're learning together here in this hunt for flight 370. you love this game.

images. moscow is calling the photographs outdated. court is in recess until monday in the murder trial of oscar pistorius. the prosecutor accused the olympic sprinter of changing his story. he said pistorius intentionally shot reeva steenkamp after a heated argument. the united states is following through on its word, refusing to issue a visa to this man, a man iran picked to be its new ambassador to the united nations. he has ties to the takeover of the american embassy in iran. he says he acted only as a translator. the duke and duchess of cambridge continue their three-week tour of new zealand. today they visited the town of cambridge, where they laid a wreath at a war memorial, honoring fallen soldiers. they also met with well wishers during a short walk on the

here's the eye-opening thing about this hack. your information hasn't necessarily been safe. heartbleed lets potential hackers utilize a tool to test if another computer is online. with this hack, the heartbeat check could force a computer to diverge secret information, including the keys to the encryption code. once hackers have the keys to this, it's potentially game over. your user names, passwords, all that data you thought was safe is up for grabs. the heartbleed bug leaves no traces, so you have no idea if or when you've been hacked. of course, these sites are scrambling to get rid of the bug, but it may be days or weeks before the entire web is fixed. what can you do about it? right now you might have to sit tight. a lot of these websites are still trying to update their code. once they have, definitely go in and change your passwords. as always, be very cautious about the information you put out there.

(music) defiance is in our bones. defiance never grows old. citracal maximum. calcium citrate plus d. highly soluble, easily absorbed. time is of the essence in the search for these black boxes, especially if they're relying on the pings from the black boxes. the flight data recorders are soon to die, if they aren't dead

already. >> a tow pinger locator and sonobuoys are being dropped in the search effort. but cnn's chad myers is going to help us here. let's look at how these things work. chad? >> christi, victor, in the big picture, this is pretty low tech. technology used years ago, tens of years ago to listen for submarines because we didn't have the technology that we do now to listen for submarines. you throw this thing out the back of an airplane, let it splash down. it's about the size of the big roll of wrapping paper you use for christmas. not the small ones, but the big fat ones you get a lot of paper on. it falls to the water. it's connected to the surface by a 1,000-foot wire. it's connected to the float on top that eventually pops open when it hits the water. then it sends the signal back up to the airplane. so very low tech. all it's doing is listening. it's not pinging. it's not making any noise. it's not looking for the bottom. it's just sitting there as a my

-- microphone, listening for the pinger. it can listen for whales, volcanos, anything. it's literally a microphone. it's just a microphone sitting there at the bottom of the ocean. it will take that sound and send it back up to the airplane, the radio signals either vhf or uhf, get back to the airplane and says, wait, we hear something. we hear pinging from that one buoy. they're not just going to send out one. they're going to send out many in a pattern, see which one can pick up the signal the strongest, that way we know which one is the closest. >> all right. chad myers, thank you. we are just edging toward the 7:00 hour officially on a saturday morning. you don't even have to get out of bed. it's saturday. enjoy it. i'm christi paul. >> at least not for a few hours. i'm victor blackwell. this is "new day" saturday. a lot going on this morning. huge standoff in nevada.

a long-time rancher and the government are fighting over federal land. and this is becoming violent now. also, the big announcement that colbert is going to be taking over after letterman retires. that's the buzz in the entertainment world today. we'll take you live to the ed sullivan theater. >> we're going to start with the latest on the search for flight 370. a late news kmps last night with australian prime minister tony abbott. he reiterated his confidence that the pingers are coming from one of the plane's black boxes. listen. >> there have been numerous, numerous transmissions recorded, which gives us the high degree of confidence that this is the black box from the missing flight. what we're now doing given that the signal from the black box is rapidly fading, what we are now doing is trying to get as many

detections as we can so that narrow the search area down to as small an area as possible. >> so those signals were detected within 17 miles of one another. at least 10 planes, 14 ships right now are in the middle of searching. >> and the crews are focused on an area about the size of massachusetts and connecticut combined. you may recall that at one point the search zone was about the size of the continental u.s. >> but remember, time is running out. the batteries on the black boxes are quickly fading if they're not dead already. even though crews may be close, those signals are coming from about three miles below the surface, which can really compromise what they hear. officials are warning that retrieving those black boxes is a massive, massive task. and here's why. flight 370 is about 200 feet wide and 242 feet long. hopefully this will help you understand this. that means from where those signals are coming from, you'd

pass the statue of liberty, the eiffel tower, and the tallest building in the world on your way down to get it. >> let's bring in cnn's will ripley in perth, australia. we have talked about the search for the black boxes. let's talk about this visual search. i'd expect it's wrapping up now, will. >> reporter: yeah, it's over for the day. the planes will be arrives over the next couple of hours or so, landing. they were out at the search area trying to maximize the daylight hours to do that visual search. weather today wasn't so great. there were showers. there was a swell. visibility was just a few miles. so we will obviously learn later whether any of the planes today spotted anything. formally what happens is they'll call a press conference with just a couple hours' notice. but day in and day out, the pattern unfortunately for the visual search has been no debris spotted. that's really tough for the 370 families, understandably so. many of these people feel that in spite of these pings and the confidence on the part of

searchers that they think flight 370's black boxes are located, the families want proof. they want something tangible, and we're just not close to getting that yet. >> will, are you getting any indication there as to when they're going to consider sending this blue fin drone down under water? >> reporter: you know, the talk behind the scenes is that there's going to be an announcement within the coming days or at least they're going to be talking about making a decision about when to deploy the submersible. you know, they want to listen as much as possible, as you heard the prime minister say, to try to narrow down the size of the search area. once they deploy that submersible t really slows down the search process. there's a lot of challenges when you send this submersible down. the depth is going to push this technology to the limits. there's a lot of silt down there. we don't know a lot about the terrain under water. there could be mountains. we talked earlier too about the size of the plane. that's assuming the plane is

intact. experience showing when a plane hits the water, it tends to break apart. so it's going to be a difficult process once they move into that next phase. >> all right. sounds good. will ripley, thanks so much for the update. and let's talk more about this investigation with cnn aviation analyst and former inspector general with the u.s. transportation department mary schiavo. >> we also have the vice president and group general manager at the company which develops underwater marine systems. and tom fuentes. let's start with mary. mary, a mistake for the prime minister tony abbott to be so confident publicly and talk about this high degree of confidence that they've detected signals from flight 370's black boxes considering all the confidence in the past and thus far nothing? >> oh, i don't really think so. i mean, he is the prime

minister. when he started these more positive discussions, he was in china. he was speaking to a chinese audience, knowing that the families were there or at least were listening. i think he was just probably, you know, putting a good face on what angus houston, the director of the joint task force, had already said. that they thought they were the pings and they were zeroing in on it. i can't take the prime minister too much to task. i suppose anybody would want to have a little bit of optimism, particularly if you knew that families of the victims were listening. >> you know, it was interesting this week -- tom, i want to pose this to you. malaysian authorities, they came out and said, look, we want to head this investigation once we get the black box, but they admit that they don't have the capability to do so, to really -- or the expertise to really look at this thing. who gets that black box once it's found, tom? >> whoever they want to get it will get it. they still are in charge of it. it's their aircraft.

it's their investigation. they're leading it. but they've already said and admitted. so that should take the worry away from people who think that they're going to just start crashing open those boxes and destroy all of the information. they've said they don't have the expertise. they said they'll rely on other experts to do it. you know, most people now believe that it'll probably -- the australians do have the expertise and the lab. the malaysians will decide who does it. if the australians do use their facility, it will be probably with ntsb and the british and the french experts. they'll probably have a combined expertise to look at it. >> tom, the blue fin 21 according to the manufacturer can cover about 40 square miles per day. the four ping signals are all within 17 miles of one another. do you think it's time to send down the blue fin? and if not, when should it go down? >> well, it's probably still a

little early. i think we heard yesterday that -- and we've been talking about it for the last couple of weeks. the pingers have a lifetime of 30 days. that's the specified lifetime. so you are required as a manufacturer to guarantee you'll get 30 days of operation. in reality, most people design a system that has what we call engineering margin. so there's more energy in those batteries. it's not outrageous for them to last 35, 36 days or even longer. you really need to narrow that search region. i think in a piece just a little while ago, you know, you were talking about the fact that sound propagates through the water column in a complex manner. just because you have 17 miles between pings doesn't mean that the pingers are in between those locations. it could be outside and propagating around, off the terrain and resulting in a much larger search area. >> tom fuentes, malaysia's transport minister said that everyone on board the missing

flight remains a suspect. but nearly two weeks ago, they cleared all 227 passengers. so do you believe that what he's saying now is only the crew is on the table or the passengers are still suspect as well? >> no, i think, yeah, the passengers are now added back. i think when they made that announcement a couple weeks ago, at the time i said that's a huge mistake. i know from, you know, the fbi with massive resources on a case like this, it would still take maybe years to clear everybody. at least certainly months. not two or three weeks. so at the time of that first announcement, i really couldn't believe they made that announcement. i think now they're making a course correction, if you will, that what they said before was wrong. >> mary, for whom is he speaking when he says everyone is still a suspect? just the malaysians or the entire investigative group, including the americans and british who are supporting the malaysians? >> or is he speaking just

basically doing a cya for the government? what i think happened is they got out in front of each other. they probably were accurate when they said -- not that they cleared people, that they weren't looking to the passengers as suspects. you know, probably let that slip. now they're trying to go back over and smooth it over and say, oh, no, no, everyone's a suspect. but the fact of the matter is that they really don't have anything on the pilots from their computers or the flight simulator. so i think realistically when they say everyone is a suspect, if everyone's a suspect, no one's a suspect. so i think it's kind of just a smoothing over for public consumption. i can't really read a whole lot into it. i can't believe all the passengers are suspects. i just don't believe it. >> all right. thank you all so much for being with us. still to come on "new day," of course, the teams are trying to narrow the search zone even more. the u.s. is thinking about how its role may be expanded if

debris is found. we'll look into how that could happen. and dreams dashed for a group of prospective college students. more on what you're looking at here, this fiery wreck that took their lives. stay close. up. a short word that's a tall order. up your game.

there's no routine blood testing. [ male announcer ] don't stop taking eliquis unless your doctor tells you to, as stopping increases your risk of having a stroke. eliquis can cause serious, and in rare cases, fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. while taking eliquis you may bruise more easily and it may take longer than usual for any bleeding to stop. seek immediate medical care for sudden signs of bleeding like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. those three important reasons are why i'm shooting for something better. eliquis. [ male announcer ] ask your doctor today if eliquis is right for you.

yep. cheers. at discover, we treat you like you'd treat you. free fico® credit score. get the it card at discover.com. so glad to have you with us this morning. you know, if parts of missing malaysia flight 370 are, in fact, found, u.s. investigators may step up their involvement. >> yeah, because this investigation so far has come up with no claims of terrorism as cnn's pentagon correspondent barbara starr reports. barbara? >> christi, victor, with all of the focus on the hunt for flight 370, u.s. government analysts and investigators are been on the sidelines a bit.

but now all of that might be about to change. as searchers potentially close in on finding malaysia airlines flight 370, u.s. government intelligence, law enforcement, and aviation experts are quietly talking about what comes next. and at what point they'll take a bigger role in the investigation. if new pings are found from the plane's black boxes. it could still take weeks to locate the voice recorder, which investigators hope will tell them what was happening in the cockpit. but it's the data recorder that may tell them the most about how the plane went doub. >> it's going to tell you what switches were moved, when they were moved, what your air speed was, what your altitudes were. it's going to give you an entire picture of what that airplane was doing. and when it was doing it. >> if debris is salvaged, more clues for the u.s. to follow.

if part of the frame is bent outward, it could indicate an explosion. if investigators find a punched-in nose cone, an indication the plane hit the water nose first. but still, the question, what brought the plane down? and if it was a deliberate act, what was the motive? there has been no claim of terrorism found by the cia, fbi computer experts found no evidence of wrongdoing on the pilot and first officer's computers. malaysian sources say the plane may have deliberately dropped to a low altitude attempting to avoid radar. that low altitude could be one of the biggest indications flight 370 was not having mechanical trouble and trying to avoid other aircraft for safety reasons. >> did you hear anybody say that there was any emergency call? why would you turn off a transponder? >> u.s. officials still theorize

that someone steered flight 370 away from land and into the indian ocean, leaving the vital questions, who and why? victor, christi. >> barbara starr, thank you so much. i don't know, have you heard about this heated standoff between a nevada rancher and the federal government over cattle and grazing land? it is getting dicey. >> yeah, and if you have questions about malaysia airlines flight 370, tweet us. use #370qs. we'll get answers to those questions. our panel is going to weigh in on how well the malaysian government is handling the investigation. defiance is in our bones. defiance never grows old. citracal maximum. calcium citrate plus d. i'm bethand i'm michelle. and we own the paper cottage.

some prized desert in nevada. about an hour and a half outside of las vegas. with dogs and tasers, these federal officers were trying to clear a roadway blocked by protesters, an incident now under investigation. >> this is america. and they are the aggressors. we're not the aggressors. >> it all began when the usblm, the bureau of land management, began seizing hundreds of cattle owned by a local rancher, 68-year-old clyvan bundy. >> the federal government is here with an army stealing my cattle. it's not seizing. they're stealing my cattle. >> bundy and his son claim it's an illegal action because the cattle and land belong to them. >> i grew up on this land, and all the rest of you did too. most of you did. and never once have we ever been kept away from going up on this land. >> but the blm and the national parks service says the bundys don't own it, the government does.

and therefore, they need to pay grazing fees for the livestock. all told, uncle sam says the elder bundy owes more than $1 million in unpaid debts spanning two decades. >> you need to leave now! >> this week, the blm said enough is enough and prepared for a battle. they had this run-in with bundy supporters. in a statement, federal authorities say a police dog was kicked and officers protecting a civilian driver were threatened and assaulted. and as for the seizure, the blm and nps have made repeated attempts to resolve this matter administratively and judicially. the dispute, however, has brought self-proclaimed members of militia groups from across the country to join the rancher in fighting what they say is u.s. tyranny. >> did you bring weapons with you? >> i just prefer not to answer. >> and there's no answer as to how long this standoff will last. dan simon, cnn, bunkerville,

nevada. >> that's a fight that's been going on for years. we'll see if there's a resolution any time soon. victor, christi, back to you. >> thanks, nick. 36 days now, and i think what shocks most people, no sign of debris from flight 370. >> yeah, there's this new sense of urgency. some people would say desperation as search crews try to find the plane's black boxes. >> next, why searchers could be closer than ever to finding a possible debris field. ♪ ♪ ♪ ben!

it is bottom of the hour. translation 7:28. you have plenty of time. i'm christi paul. >> i'm victor blackwell. pleasure to be with you this morning and every weekend. here's the latest on the search for malaysia airlines flight 370. a lot has happened overnight. >> definitely. the australian prime minister specifically. i think a lot of people are listening to him right now as he says he is confident four signals detected by a high-tech u.s. pinger locator are, indeed, coming from one of the plane's black boxes. >> and those signals were all

detected within 17 miles of one another. that means that the 10 planes and 14 ships conducting today's search are focused on one of the smallest search zones to date. >> let's put this in perspective. take a look at this map. you see massachusetts and connecticut there highlighted in red. that is the size of today's narrowed-down search zone. you might remember at one point the search area was about the size of the continental u.s. in its entirety. >> progress, but still two u.s. states is the size of this search area. time is ticking away for the crews. the batteries on the plane's black boxes are quickly fading, if they're not dead already. and although those signals were detected relatively close to one another, they're also coming from about three miles below the surface. >> let's talk about it with a safety analyst and the author of "why planes crash." >> and david stupples is a professor at the university of london. okay, gentlemen. good to have both of you.

we haven't heard about a new ping in a couple of days now. are you of the mind -- and let's start with you, professor -- that the batteries are already dead? >> well, i couldn't say whether the batteries are dead at the moment, but they certainly will be getting a lot weaker, and the signal strength will be falling away quite rapidly, which also means that the frequency will be falling away as well. >> david, i wanted to throw this to you. we have a question from michael on twitter. actually, from david on twitter. had never even thought about this before. but it's interesting. he said, is it possible to remove flight data and cockpit recorder from a 777? in other words, could they have been dumped as a diversion? >> you know, that's something i hadn't thought of either, but it would be extremely difficult,

first of all, to get to it from the cabin area. you'd have to take them -- they're in the back of aircraft. they'd have to be taken out, brought forward. the best way take it out of the aircraft would to take it to the equipment bay and drop it overboard through the outflow valve, which is in the bottom of the bay. that would be about the only way you could do it. again, it would be extremely difficult if not impossible to get it from the tail of the aircraft into the interior of the aircraft. >> professor stupples, i wonder about your level of optimism. we were hearing a lot of it from air chief marshall houston, also from the prime minister tony abbott. the p3 orion has been modified to pick up these sounds, and the signals they're picking up are not at 37.5 kilohertz, which is the frequency at which the pinger locator emits the pinger.

how confident are you? >> well, for the pinger itself, that's the towed ping locator, it will be a fairly broad reception bandwidth. therefore, it will certainly be able to receive 37.5, but it will receive signals at some distance either side of that. i think it will probably go down to about 10 kilohertz. if being transmitted, it will have received it. >> so david, if australian search teams do find the black box, let's say, what are the chances that they're going to find the plane as well? we ask that because you wonder how far debris spreads across the ocean floor. >> well, it depends of course on how the aircraft broke up in the first place. if it was a mid-air explosion or something, it could be spread for miles. if it's something that was caused by the impact on the water, it would be probably

within maybe a mile or so. but the black boxes, remember, are attached to the structure. so they wouldn't be expected to be far at all, if not right at the area of the most debris. >> so question, i'm going to come right back to you, david, with a question from someone on twitter using #370qs. this one is from john craig jr. why can't they design a black box that floats and has a gps? i wonder if that's possible even, but i guess the question gets to, is there an easier way to get this information? does it always have to be this difficult? >> yeah, there is, actually. there's a patent on a product that's an ejecting box. the military has been using this for a while, as a matter of fact. and it was recognized in the safe act following 9/11 to be deployed. but no action has been taken on that. they haven't followed that forward. the box comes out. it's ejected either by the impact or if it doesn't work, then it's ejected by pressure

from the water. it works like an epirb, which is an emergency radio beacon used on ships. so it doesn't need to be gps on it. what happens there is it sends out a frequency at 406 megahertz. at that, it's triangulated upon by 16 satellites that continuously are available to provide that location. so, yeah, there's much better technology available right now. >> david stupples, why do we not at this point, since we've honed in on the small eest search are they've had yet, deploy that blue fin underwater drone? >> well, the blue fin can probably search out about 40 square miles a day at maximum. but realistically, it's going to be 10 to 20 square miles a day. if you think at the moment, we've got 140-mile area to search. that will take a considerable amount of time. so what they're hoping to do is

reduce that down to probably around about 50 square miles and then if they can do that, then they will deploy blue fin and hopefully find it probably within a month. >> all right. hopefully within a month. thank you both for joining us this morning. good to have you both. >> thank you. we have now reached week five. you wonder how long these families can endure the ups and downs and twists and turns of this investigation. we are going to hear from some of the loved ones who are still waiting for any word on the fate of this flight.

ameriprise asked people a simple question: in retirement, will you outlive your money? uhhh. no, that can't happen. that's the thing, you don't know how long it has to last. everyone has retirement questions. so ameriprise created the exclusive.. confident retirement approach. now you and your ameripise advisor can get the real answers you need. well, knowing gives you confidence. start building your confident retirement today.

well, it's been more than five solid weeks now, and i'm sure many of the families would call this torment. i mean, just the leads and then nothing about flight 370. and these families are not just waiting. they're not just sitting there grieving or pressing investigators for answers now. they are doing those things, but they're also organizing. they formed a committee of sorts to speak and make decisions for the group. each family gets one vote. >> and in the absence of any physical evidence of the airliner, no number of leads or theories is going to erase their hope. would you? one passenger's mother spoke to our nick robertson in kuala lumpur. listen to this. >> inside, my heart is telling still they are alive. all the passengers are alive.

>> another family member spoke with our anderson cooper. >> like most of our other families, i continue to push by asking more questions. sooner or later, we're going to get to the truth. i mean, either we're going to find the plane and there will be a conclusion found as to why it was taken or why it was crashed. and so whether the continued data that we're getting is cob substantiately changed or not, we still have to keep asking for it. it's a real quandary. on the one hand, i want to be a logical and thoughtful person and say, okay, i get it. the plane has crashed. we need to find the black box, and then we can discover what happened. you know, the scientific line of inquiry says there was probably some catastrophic failure on the flight and the pilots were able to stay in control just long enough to get the auto pilot n

conked out and the plane kept going. i can accept that's likely. but emotionally, it's impossible to accept that because it means there's no more hope. if we run out of hope, we stop asking questions, and then the investigation dies. so we just have to keep asking until we find something. hope is the only thing that we have. and the minute we give that up, we have to fall into a grieving cycle, and we can't do that until we have evidence. so, you know, i think a lot of outsiders think the families are just being irrational, but we're not. we're protecting our emotional health. and we wants answers and we want to keep pressure on the government agencies involved to find those answers. >> such a great explanation, wasn't it? >> it was. and i think there are a lot of people who do understand exactly the perspective of the families. unless you show me something, not just tell me, show me something, of course these families are holding on to hope. most of the passengers on this

night that was headed to beijing are chinese. other are from australia, some from new zealand, india, also a few from the u.s. as well. >> yeah, let's actually go to cnn's sumnina yuda. she's in kuala lumpur. she has more from the transportation minister. so what did he say this morning? >> what he said is those sounds the australians have been hearing, that is a promising lead, especially because they sound like the sound that would come out of a black box. still, he says all of that needs to be verified. the malaysian authorities are still cautiously optimistic. have a listen. >> signals need to be verified. i agree with angus houston that any lead, and this might be one of the more cautiously optimistic leads that we have, because the signals are similar

to a black box. >> you can understand the hesitation there because there's been so many false leads in the past few weeks. the malaysian authorities want to be absolutely sure before they jump to any sort of conclusion. christi? >> we heard from one passenger's mother, another passenger's partner. what else are you hearing from the relatives and the loved ones of the passengers on the plane? >> well, most of the families we've heard from, they're not happy with the way the investigation is going. we just heard from the mother of one of the iranian passengers on board. she said she simply doesn't understand how that mane could have flown for so many hours and how nobody could have noticed. she said she's still having sleepless nights. she thinks that the malaysians aren't following up with this investigation enough. she hopes, she says, that the americans are still investigating this because she has lost faith in the malaysian

authorities. and she says without the evidence -- and this is, of course, what most family members here are saying. without that evidence, without seeing some sort of debris or wreckage, they just cannot believe that they've timely lost their loved ones. so they're still clinging on to hope, christi. >> sumnina, thank you so much. all right. coming up, this search for the black boxes and for the wreckage will take us to a place that few have ever seen. miles, three miles, under the sea. >> so you wonder, how deep is that? and has anything ever been found that far below the surface? co: sometimes you don't know you need a hotel room until you're sure you do. bartender: thanks, captain obvious. co: which is why i put the hotels.com mobile app on my mobile phone. anyone need a coupon? i don't. [ male announcer ] how did edward jones become one of the biggest financial services companies in the country? hey.

yours? not anymore. come on in. [ male announcer ] by meeting you more than halfway. it's how edward jones makes sense of investing. a man who doesn't stand still. but jim has afib, atrial fibrillation, an irregular heartbeat not caused by a heart valve problem. that puts jim at a greater risk of stroke. for years, jim's medicine tied him to a monthly trip to the clinic to get his blood tested. but now, with once-a-day xarelto jim's on the move. jim's doctor recommended xarelto. like warfarin, xarelto is proven effective to reduce afib-related stroke risk. but xarelto is the first and only once-a-day prescription blood thinner for patients with afib not caused by a heart valve problem that doesn't require routine blood monitoring. so jim's not tied to that monitoring routine. [ gps ] proceed to the designated route. not today. [ male announcer ] for patients currently well managed on warfarin there is limited information on how xarelto and warfarin compare in reducing the risk of stroke.

xarelto is just one pill a day taken with the evening meal. plus, with no known dietary restrictions, jim can eat the healthy foods he likes. do not stop taking xarelto, rivaroxaban, without talking to the doctor who prescribes it as this may increase the risk of having a stroke. get help right away if you develop any symptoms like bleeding, unusual bruising, or tingling. you may have a higher risk of bleeding if you take xarelto with aspirin products, nsaids, or blood thinners. talk to your doctor before taking xarelto if you have abnormal bleeding. xarelto can cause bleeding, which can be serious and rarely may lead to death. you are likely to bruise more easily on xarelto and it may take longer for bleeding to stop. tell your doctors you are taking xarelto before any planned medical or dental procedures. before starting xarelto, tell your doctor about any conditions such as kidney, liver, or bleeding problems. xarelto is not for patients with artificial heart valves. jim changed his routine. ask your doctor about xarelto. once-a-day xarelto means no regular blood monitoring -- no known dietary restrictions.

black boxes which can be two to three miles below the water. let's put this in perspective of the mock up of the boeing 777. here on the surface, we have the "ocean shield." we put the landmarks on the surface. here is the statue of liberty at 305 feet. if you tip it upside down, it takes you deep below the surface. then the eiffel tower. the tallest building in the world is the burj khalifa. we continue to go thousands and thousands of feet below. the tpl, the towed ping locatcl, is 346 feet. this yellow dot here can pick up a signal two miles away. now we crossed the one-mile mark and continue to dive and

continue to dive until we get to 8,100 feet. the hmas "sydney" that sank back in the '40s. continue to dive. we are past 2,000 feet. we are about to 12,000 feet where the wreckage from the "titanic" was discovered. 12,500 feet about 70 years after it sank. the hms sydney and titanic opens we can get this wreckage without a signal. that is what searchers have to do without the batteries of the black box and once they die. that took some time, of course, air france at 13,000 feet. then we get to the pinger likely at 14,500 feet. you see this line here, this

ridge, this is an outline, if you were to tip washington state's iconic mt. rainier upside down, you get to the peak of it at about where the pinger is. 15,000 feet below the water. that gives you an idea of how far this locator has to pick up a signal and where the black boxes are likely. christi. >> you don't want to say where is it. it is not that easy. after more than three decades on tv as we switch gears here, were you surprised to hear late show host david letterman is retiring. we are interested to see what kind of comic relief his successor is going to bring. a live report coming to you from perth, australia momentarily, but first here is your travel insider. welcome to portland, maine. i'll show you some of the best

♪ new york ♪ well, after 33 years on the air, late night host david letterman says he'll retire from the late show some time next

year. not the entire 33 years on one program. >> i love the whole some time next year. that's a tease. i wonder if he will go away one night and another host will show up the next like stephen colbert. a lot of people are wondering where do we go from here? >> some people are excited and some are not. we have alexandra field with more. >> reporter: a lot of surprises, christi and victor. a week after david letterman announced he stepped down that cbs announced stephen colbert would replace him. we don't know what the show will look like from a creative standpoint and when the transition womill happen. we know the one thing the show will not include. >> i have to tell you, i do not envy whoever they try to put in that chair. >> reporter: stephen colbert ready to take the microphone from david letterman.

the 2015 transition ending a late show era. >> paul and i will wrap things up and take a hike. >> reporter: but colbert's beginning will mark another ending. he will retire stephen colbert, the character. the character he plays on "the colbert report." >> the truth is anyone can read the news to you. i promise to feel the news at you. there is no bigger fan of bill o'reilly than bill himself. but i am a close second. >> reporter: the routine has won him plenty of fans and, yes, some critics, including real life conservative rush limbaugh. >> cbs declared war on the heart of america. >> colbert has been mocking conservatives for a decade.

i'm not surprised rush limbaugh is not happy with the choice. i think a lot of other people will. >> reporter: that is what cbs is counting on, but who is the real stephen colbert? >> we're about to see a great reinvention take place. someone we know has played a character for a decade. >> reporter: we caught rare moments of stephen colbert in 2010 when he was called to testify. >> migrant workers suffer and have no rights. >> reporter: his heartfelt words stemming from made-for-tv moments in the segment on his show, colbert spent the day in the life of a migrant worker.

this is "new day saturday." we want to get to the latest on the bus crash in california. and the latest on the woman hurling her shoe at hillary clinton. we will have more coming up. we begin with the desperate search of missing flight 370. four days after the latest ping heard in the ocean. now they are battling the sound of silence this morning. are the batteries on the plane's black boxes dead? have they run out? >> prime minister tony abbott says he is confident that the pings are from one of the plane's black boxes. listen. >> the numerous trends recorded which gives us the high degree of confidence that this is the black box from the missing flight. what we are now doing given that the signal from the black boxes

rapidly fading, what we are now doing is trying to get as many detections as we can so that we can narrow the search area down to as small an area as possible. >> so those pings were detected within 17 miles from one another. what that means is the ten planes and 14 ships wrapping up the search today are focused on the smallest search zone to date. >> let's put that to perspective. look at this map. massachusetts and connecticut highlighted in red. that is the narrowed search zone. you may recall the search area was about the size of the continental u.s. this is a smaller zone, but a lot to search. >> the concern here is the crews are close to finding these, but the signals are coming from three miles below the surface. all this as the black box batteries may already be dead. joining us to discuss the latest

on the investigation here is cnn analyst michael kay and miles o'brien. >> miles, i have a question for you. we are accepting questions from #370q. the question is do you feel on the flight path it was under the pilot's control. that is from michael rustin. >> victor, it was under the control of a human being. we have to be careful about who we say was flying the aircraft, of course. there is no question given the flight path there was human input. we have to leave it at that for now. was it the flight crew or was it someone from the back of the plane who somehow got into the cockpit and commandeered the flight. there is nothing, of course, indicative of an auto pilot gone wacky. put it that way. >> i wanted to ask you, michael

w kay, we are getting so close and now we have nothing. is it time to send the bluefin drone under water? >> we know the batteries last between 30 and 40 days. we are sort of on the transition of have the batteries completely died and start launching the auvs. it is a difficult judgment to make that angus houston's got. i think he will probably keep the search going for the pings for at least three-to-four days. we are taught by experts that the batteries will last 30 to 40 days. he wants to make sure he follows that before he puts the process of putting the auvs down there and searching the area. that is going to take a long time. when angus houston makes that decision, we have need to be prepared for the long haul. >> one question that received is so there is a search for the

black box. and we know that in other crashes, sometimes the black boxes don't have everything the investigators hope. is there any chance that once this black box is retrieved, miles, that the cards inside, the information could be so damaged you don't get the answers? >> sure. there is a good chance of that. these black boxes are designed to handle a lot of g-forces and a lot of heat if there is a fire. that wouldn't be relevant in this case. sometimes they don't work. most of the time they do, however. most of the time the clever technicians who know how to read these cards, whether at the ntsb or expertise in australia, should be able to recover something. they have a high probability of success of getting something out of it. my concern is this that the cockpit voice recorder captures only the last two hours in time on a loop. so this is a flight that

extended over seven hours. we have to wonder what that last two hours offered in the way of conversation or statements or any sort of human voices. there may not be much on the cockpit voice recorder. you don't know. the other aspect is the flight data recorder which measures all the inputs to the controls of the aircraft. 80 plus inputs from the settings and power settings. you name it. it could tell us if there was a mechanical failure or say sabotage or a small bomb or something like that. rapid decompression. you name it. if it shows the plane was working well all the way into the water, that would tell us it is a deliberate act, but it would not tell us who is responsible for the deliberate act. since we don't have black boxes for human beings, there may be questions after this time it might take to get the black boxes to the surface.

>> michael kay, does it alarming you that they have not been able to find one piece of debris yet? because this investigation at this point is completely turned backwards. usually you have debris and then you have the black boxes. >> i think it is a really good point. we have to remember that there are three ways in which we can discern the first part of the investigation. miles made a good point earlier on. we are talking about the why at the moment. before we get to the why, there is the where and the what. once we get the black boxes, how do we get that and then how did it come to the final resting place. there are three ways to find the phases. it is important to remember the number one priority is to get closure for the families. that is the where. that is through the airborne search looking for any signs of

debris linked to mh 370. the second is the debris on the surface of the ocean. that is a long time to trawl. we had the discuss on the launching of the auvs. the third way is bypassing the haystack and identifying the needle which is the black boxes. we have to concentrate on all three to discern the where. i can't think of a case in history where we bypassed the haystack and gone to the needle, the black boxes. it is important to discern between the search areas. the location where the four pings heard 17 miles apart. there is 18,000 square miles of the airborne search. that is the p-8 and p-3s. they are all active in trying to find out the airborne bit. >> so, michael, one more

question back to you. the air chief marshal houston said they will wait for visual confirmation before they send down bluefin. i imagine he would have to walk that back if the confirmation doesn't come. if you don't find the debris, at some point you have to send the bluefin down. that would come in a few days? >> you are absolutely right. i think australia has done a wonderful job in reenergizing the search. we know there were problems with malaysia 370 first went missing. i think air marshal houston is in a place does he keep on searching with the ping locators or the auvs. he mentioned the fact he needs some sort of physical wreckage or debris to corroborate the search location, but i think also, if he finds the black boxes, that is another trigger

to launch the auvs. we are in a place to build our expectations for the long haul. i expect over the next few days if they don't hear anymore from the pings, we have to go into the second big phase of the operation, that is launching the auvs into the location where the pings were heard. that will take a long time. >> all right. if you gentlemen will say with us here. we want to get to perth, australia because we have -- who is there? matthew chance is there. matthew, are you hearing about what they found in today's search? >> reporter: no, we haven't had actually much detail in terms of what's been coming out of the search zone for the past 48 hours. there has been no press conference given by angus houston. information has been only

drip-fed to us. it indicates the kind of lack of progress or lack of concrete developments that they achieved over the past 48 hours. we know that there have been expressions of further confidence by the australia prime minister who is on an official visit to china. he is certain or confident at least that the signals monitored are from the black box flight recorders from the missing malaysia airliner. he is warned it could take time for the black boxes to be recovered. we are in a bit of a hiatus. we are confident the search area, beneath the sea, is continuing to shrink. about 16,000 square miles at the moment. it is 18,000 square miles at this time yesterday. there is nothing concrete that they have the black boxes.

>> i want to go to miles. you have been highlighting there is nothing pointing to any criminal activity on behalf of the pilots. we heard from malaysia airlines that they spoke to sky news that everyone is a suspect still in their view. what do you think about that so many weeks on after hearing initially that the passengers had been cleared? miles? >> can michael kay answer that question? >> let's go to michael kay with that question. >> i think that the fbi and there will be a lot of investigational authorities that are looking at that aspect of the investigation and i think it is important at this point to remember there are six countries involved in this as the uk and the ntsb and you have france and

you have china and you have australia who are conducting the search operation and malaysia and the investigator in charge. there is a lot of horsepower looking into this with the operations and worthiness and medical factors. what i'm invested in is trying to understand the where and the what bit and the why bit. that something i'm trying to steer away from. we don't have enough evidence to go down a specific route. we have enough evidence to keep all the cards on the table, but not enough evidence to take any off. we have to keep a broad mind and not go down a rabbit hole too quickly which is the why bit and phase three. >> michael, this question is from twitter from david. he brought up a scenario i have not heard of yet. he wants to know is it possible to remove the flight data and cockpit recorder from a 777.

could it have been dumped as a diversion? >> that is highly unlikely. that is a scenario that i just can't envision to be honest. i think what we need to do is we need to keep vested in what the realities of the search are. there is not a lot of information about this. there is so precedent. it is one of the most mysterious accident investigations in the history of aviation. we need to keep ourselves anchored in the realms of reality. i mentioned this earlier in the ntsb investigation. these organizations with the uk and u.s. have a serious amount of experience and credibility when it comes to looking at accident investigations. we need to have the confidence in the information that they are giving us. for example, the aaib was working with inmarsat. there are a lot of people who have doubts about that.

at the moment, we have to maintain confidence in those authorities and they are working on the accident investigations. >> that work continues. michael kay and miles o'brien and matthew chance, thank you all. we want to tell you about other stories we are following. in california, the college tour for high school students, went horribly wrong. we have new information about that. we will let you know. and hillary clinton. dodging a shoe in las vegas. >> you have seen the video, but now we know who threw it. ♪ honestly, i'm pouring everything i have into this place. that's why i got a new windows 2 in 1. it has exactly what i need for half of what i thought i'd pay. and i don't need to be online for it to work. it runs office, so i can do schedules and budgets and even menu changes. but it's fun, too -- with touch, and tons of great apps for stuff like music, 'cause a good playlist is good for business.

♪ rise and shine. bottom of the hour right now. i hope saturday morning has been good to you. i'm christi paul. >> i'm victor blackwell. australia prime minister tony abbott is confident that the four signals detected by the high tech u.s. ping are locater is from the black boxes. >> we should point out this morning, at least, ten planes and 14 ships are scouring the smaller area that is now roughly

the size of massachusetts and connecticut combined. the smallest area they have been able to hone in on. >> let's dig in on the panel of experts with david soucie. >> we have raymond mccord. gentlemen, thank you for being with us. >> captain mccord. let's start with you. almost four days of silence for the teams looking for the underwater pings. do you think the beacon has stopped or they are not in the right position any longer? to what do you attribute to that? >> the pinger is like a battery like a flashlight. the flashlight gets weaker. same with the pings. they have to be closer to the beacon to hear it. they have all of this data they had from the various pings they had over the day and they

identified this area. the 16,000 area mile area. they probably have gradient in that area. they have a higher probability and as you go further away from the center, the probability is less and less. they are probably trying to refine and get an idea of where they think the pings are and black boxes are so they can start from a specific point on the side-scan sonar search. >> tom, transparency has been an issue. people have been listening and they have the information a long time ago and they are just releasing it. certain countries are making discoveries, obviously, and there is belief they are not sharing that information with the other countries because they don't want to reveal their tactics and resources that they have. do you think that that has hindered this investigation? >> i don't know necessarily,

christi, it would hinder it. i would think that is happening from all sides. our own u.s. navy is not saying a u.s. navy submarine was deployed in the investigation. the british announced they deployed their submarine, "the tireless." we have heard nothing more about that. all of a sudden, they dropped the ping locator in the water and find pings. you know, we don't know. the main issue is if the countries have any information that would place a location to search and the search goes on, there is no hindrance. whether we know why they search there or not. >> david, a question from twitter from jim tallton. he asks, help us understand what happened to a plane out of fuel at 35,000 feet. does it glide? does it coast? what happens? >> it can glide for many miles. what happens when it runs out of

fuel is two different options. one is if auto pilot is engaged and one is not and then the third is in control by the pilot. if the pilots are incapacitated, it will find a center. the aircraft has dyhedral wings. it tilts to one direction, the lift on the top wing decreases. it naturally finds its center if it has been trimmed properly if it is traveling that far. the airplane could have a glide slope in. the auto pilot will try to hold altitude. the aircraft would go into almost a 40-degree pitch before finally stalling. once it releases, the auto pilot would release because of the pressure on the control. it would dive and stall and go down at this point. you have a dramatic fall at this point over 15,000 feet per minute. >> captain mccord, how long do

you think other countries, australia, obviously the u.s., china, you would think would stay in the game here. how long do you think we have the multinational presence here? will there be a time when countries say i'm out? >> i think they will stay in it for a while at least until they recover the black boxes. i think at that time, we have to have a decision made on what happens after that. after the data from the black box. >> what happens after that? who do they decide who gets it? >> it will be malaysia airlines as the lead on this. however, whatever the results come out on whatever they want to recover anything, the recovery is very expensive and time consuming and someone has to pay the bill on that. they have to make an effort and determine how it will be funded and what assets will be brought

to the table at that time. >> tom fuentes, sarah bajc told cnn the fox is in the hen house here. i will quote her here. we have a country, malaysia, who has all the primary liability in the case. i want you to speak to that. has there been over the last 36-day, any systems of checks and balances that ms. bajc is not conducting this information in a way that benefits them considering the level of liability they hold? >> i think, victor, the way the investigation is going to come out, i'm not sure that is the case or not. the way the investigation is going to unfold, when they find the boxes, it will say exactly whether the plane went up in altitude or down or made a left turn or right turn. the exact routing will be

determined at that time. we may never know why it turned or who was in control to make it do those turns. i think that the idea that the malaysians would be covering it up at this point on purpose, i think there are too many people involved and too many experts looking at the data and conflicting data. i don't know it is strictly a cover up. >> all right. david soucie and tom fuentes and colonel mccord, thank you very much. we are also talking about the heartbleed bug and how you can protect yourself. david letterman is retiring and fans are looking forward to what this guy, stephen colbert, has in store. araway p who tr where castles were houses

ameriprise asked people a simple question: can you keep your lifestyle in retirement? i don't want to think about the alternative. i don't even know how to answer that. i mean, no one knows how long their money is going to last. i try not to worry, but you worry. what happens when your paychecks stop? because everyone has retirement questions. ameriprise created the exclusive confident retirement approach. to get the real answers you need. start building your confident retirement today. it's how i look at life.

especially now that i live with a higher risk of stroke due to afib, a type of irregular heartbeat not caused by a heart valve problem. i was taking warfarin but wondered, could i focus on something better? my doctor told me about eliquis for three important reasons. one, in a clinical trial eliquis was proven to reduce the risk of stroke better than warfarin. two, eliquis had less major bleeding than warfarin. and three, unlike warfarin there's no routine blood testing. [ male announcer ] don't stop taking eliquis unless your doctor tells you to, as stopping increases your risk of having a stroke. eliquis can cause serious, and in rare cases, fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. while taking eliquis you may bruise more easily and it may take longer than usual for any bleeding to stop. seek immediate medical care for sudden signs of bleeding like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures.

those three important reasons are why i'm shooting for something better. eliquis. [ male announcer ] ask your doctor today if eliquis is right for you. [ male announcer ] ask your doctor today i missed a payment. aw, shoot. shoot! this is bad. no! we're good! this is your first time missing a payment. and you've got the it card, so we won't hike up your apr for paying late. that's great! it is great! thank you. at discover, we treat you like you'd treat you. get the it card with late payment forgiveness. we're learning more about the final moments of flight 370. officials say now the plane's pilot was the one who signed off before the 777 vanished. >> meanwhile, malaysia airline is making sure no pilot or co- pilot is ever alone in the cockpit. there are people who question if the crew members sabotaged the plane. >> let's bring in robbi.

astounding that no evidence that either of the pilots took down the plane. we want to make that clear. those close to the pilots describe him, the captain, as a man who was so passionate about his job. let's listen here quickly to something that one of his friends told cnn's erin burnett this week. >> the captain that i know would never have put the lives of his passengers in danger or his plane at risk. that is not the man i know. >> that's not the man i know, he says. we were sitting here thinking how plausible is it that someone could have some psychotic break and decide at the last minute to crash a plane without any warning signs? >> you know, it is very unlikely. a lot of people think a psychotic break just happens without any notice. that's really not the case. there is always some kind of sign if you look years back.

there is some kind of oddity that goes on in a person or look at their family history of a sense of illness there. >> let's look at the families here. we heard from her earlier today. sarah bajc. she says she just does not believe that this plane went down into the south indian ocean. let's listen in her own words. >> it's the time that i'm alone that i feel him the strongest and i can only feel him. i can't have him next to me. so, my mind is so confused by what my heart is telling me. >> i think i've come to a realization that for sure that the flight is still in tact and the passengers are still alive. >> i do believe there is some sort of cover-up by some sort of government agency. >> i think i felt his spirit

since i met him. maybe what i was confusing as his physical presence has always been how his soul has connected to mine. >> we saw a range of emotions there, robi. reconcile those for us. her mind and her heart are in conflict here. >> you know, sarah really beautifully describe what is many members feel there is an ambiguous loss. there is no body. it is not clear what actually happened. they vacillate and go back and forth with the fantasies in their minds. one moment they might feel like the plane is at the bottom of the ocean and another moment, they imagine a different scenario, a more positive scenario where the plane landed somewhere and their family members are alive and well. that's the problem without having a body. there is no funeral. there is no definitive information. so very often their grieving process hasn't even started to begin yet.

it is almost frozen in time. so for many of these family members, they really don't know what to believe and sometimes that leaves them believing the more positive outcome, which is the family member is still alive somewhere. >> i think parents with missing children probably go through some similar because it is ambiguous. >> yes. >> on that note, when we think of what the families are going through, if you were counselling them right now or counselling anyone with a situation where they don't know if somebody is dead or alive, how would you counsel them? what would you say? >> you really have to support where they are right now. right now, their family member is missing and to try to deal with that upset and that loss. very often family members want as much information as they can get. that certainly should be supported. a therapist needs to acknowledge they are just doing well and just trying to survive and they

should just honor the fact they are missing their family member now even though there is a big question mark as to what will happen in the future. very often these family members are limping through life and other people don't know how to deal with them, they often avoid them. it is really a process. it happens over time over the years when they realize this person is never going to come back. they deal with just that missing them in the moment. >> wow. >> robi ludwig, so grateful for your expertise this morning. >> sure. >> you can learn more about coping with sudden loss at cnn.com/impact.

comedian and talk show host david letterman is retiring from late night "the late show" some time next year. >> some time. i think one night he will just go away. the next thing you know, there is stephen colbert. he is replacing him.

the man chosen. that has a lot of people going what is this new version of late night going to look like with stephen colbert. >> i wonder if he is going back to colbert. the correct pronunciation of his last name. let's check in now with alexandra field, who tells us what folks are saying in new york. alexandra, hey. >> reporter: hey, christi and victor. stephen colbert came to fame playing a conservative pundit on the colbert report. when he takes over the late show in 2015, he plans to retire that character. that is all we know about the new show. cbs is not saying creatively what the show will look like with colbert as host. it will give fans a chance to meet the real-life colbert. that is something they are looking forward to. >> a little sad. it's weird. leno's gone and letterman is going. i love colbert. i'm totally for that. >> i don't know if i like this. >> why don't you like it? >> because i love colbert in his

persona as a political commentator. i'm not sure he will do that. >> i think colbert is great. i went to northwestern university with him. he was well known for being a great comedian then. it is the best news. >> reporter: we will see what we get. not everyone is sold on the idea. rush limbaugh calling colbert alienating. letterman is lending support calling colbert a real friend. as for the competition, jimmy fallon also weighed in. he said don't expect a late night war between the two of them. maybe just a dance-off. i would watch that. how about you? >> what is your vote? colbert or colbert? >> alexandra? >> reporter: colbert. colbert is the name we all know. it is the name that he made for himself. he has to stick with colbert. >> if he came out with colbert,

people will say what are you talking about? >> stephen colbert. >> doesn't have the ring. >> alexandra field, thank you so much. thank you at home for starting your morning with us. we will be back here at 10:00 eastern. >> we have something special coming up at 10:00. fabian cousteau will be with us. he said there are things about this area in the southern indian ocean where they are searching for the plane that we really need to know about. he will walk us through that at 10:00. you know what is coming up next. >> yes, absolutely. michael smerconish with interviews with the people who go down to these levels. deep sea divers who know a lot about the areas. be sure to join us at 10:00. right now, stay tuned for "smerconish."

good morning. i'm michael smerconish. one week ago at this hour, i stood here someone incredulous and said a chinese patrol ship picked up a pulse signal in the south indian ocean. that was last week anding in no has been found. no oil slick and no sightings of the missing plane. we heard this word overnight. it is not a word associated much with the search, but that is apparently changing. >> there have now been numerous transmissions from the black box or from what we are confident is the black box that have been picked up by the various devices which australia is
