the data that gives us an idea where to look. >> disagreement on this panel. a lot of experts in the field. it shows the complicated nature of the search, why it's being pulled in several directions and why it has taken so long and where flight 370 went, what happened to it remains very much a mystery. cnns coverage of the search continues right now. i'm john berman in for fredricka whitfield. we are covering the flight of 370. a lot of developments today. in four hours, searchers will be over the ocean looking for three now, three objects they have not been able to identify. images of a third object were captured by a chinese satellite four days ago and released to the public today. the object, 74 feet by 43 feet.

just to be clear, satellite imagery from china now, has captured picture of what could be debris off the coast of australia. this is in addition to the two pictures taken about a week ago now that australia has been looking into to get a visual confirmation of. china is sending ships to try to locate this piece of possible debris to determine if it is wreckage from the plane. it's about 75 miles from the two other objects, possible floating objects spotted by the commercial satellite one week ago. the search for all three of them could be complicated by bad weather. conditions earlier today were good enough. crews managed to see several small items in the ocean, including a wooden palette. none of the items got investigators excited. they do not think they are substantial leads. family members of those on board flight 370 have been on an

emotional roller coaster ride. every new satellite image we are seeing. many families increasingly frustrated by the way the government is handling the crisis. today, the frustration boiled over during a briefing with malaysian officials. take a look. >> we are here. >> malaysian officials say the one thing the families want to know, they can't tell them. that's, of course, what happened to flight 370. we have a lot to talk ability. we gathered a fantastic panel of experts to stay with us for the hour. rick in washington is an aviation specialist. tom is a cnn law enforcement analyst. from denver, david is the author of "why planes crash." thank you all so much for joining us. david, i want to start with you.

this new image from the chinese satellite. 75 miles from where those other images of possible debris were found one week ago. how much of a reason for hope is this now, david? >> i don't know if it increases my hope at all. what it does is increases my optimism they will be able to find what this is because at least now, if it is the same object, they have the track on the direction it's going, approximate speeds. in that area, it could change quickly. this is two days old. we'll have to see if that pans anything out. some people are discounting this second image because of its size. well, at accident sites, this material could be flipping and be a bunch of small pieces with that structure because of the stringers inside of it. it could be a lot of small pieces strung together with

electrical cables and mechanical cables. i'm not discounting it, but it gives me hope they will find something down there. we have had two hits on what appears to be similar. >> david, just to be clear, at a minimum, it gives greater specificity in a greater search area? >> it would in my mind, yeah. >> rick, you think, though, this piece of debris, you think it may be too big to get excited about? some 73 feet by over 40 feet? >> i didn't really comment on the size. there was another comment earlier about the size. i'm certainly not an expert at looking at satellite photos and the kind of terrain with the wave action, the sea states and the other pieces. but, i guess my point was, i wouldn't solely function on one piece of debris with my entire search team. i would certainly look along both arcs based on the ping. it's not unusual to have

engineers and lawyers disagree about where to look for things. i like to base it on science and the available data. the available data from the satellite is fairly reliable. a ping is awfully reliable for determines an arc where it has flown. i was go on either side of the arc down in the sea and go along the arc looking for radar data and pull tapes over a seven to eight hour period for some of these countries. because of the air defense mission, many of these organizations will not release data to show you one, how good the radar is, or two, how poor it is. whether or not it's properly maintained and actually works. >> daniel, you served in the navy, you were a naval aviator and were involved in searches. you were involved in searches that may not have been as complicate and they were still difficult. >> at the end of the day, even in this search, somebody has to

put an eyeball on the object in the water. it's a difficult thing to do, extremely difficult. you can be at 50 feet and still mistake a white object like that for a white cap in a heart beat and your eyes play games with you. it's a very difficult thing to do. in the navy, we had the luxury of having a landing strip there, the carrier where we could go back and continuously look for the downed aircraft. you don't have that luxury here. you have two hours on station and a very dangerous environment because if anything mechanical goes wrong with the aircraft up there, they have few options, except to try to make it back 1500 feet or 1500 miles. >> it's a long way from perth, australia. 1500 miles. they have two hours over the search area. clearly, that's complicated the situation. tom, i want to talk about another complicated situation. we are two weeks since the plane disappeared. as time goes on, does it make it

less likely to get a break in the case in terms of the investigation if there, in fact, is anything to find there? if it wasn't simply something mechanical. at this point, will it be harder to discover? >> john, i think you are right, as time goes on there could be other pieces of information come up with interviews from former colleagues, friend or family or something else come up with one of the passengers. so far, we don't have that. to do complete backgrounds on hundreds of people, which is what's happening in this case, you know, it takes a long time. they have done the searches of data bases. there's a lot more that has to be done and learned about the people involved in this. you are right, it could be something more that could come up regarding the people. >> we have talked about the list of noes. the no chatter from possible terrorist organization. nothing found in the background checks.

granted, they would like to do more on people on the plane and the pilots. we have a long list of noes. is that discouraging? >> not necessarily. we have had all the cases in the u.s. of the lone wolf, where they don't disclose to family, friends, schoolmates, others that they have a terrible act in min mind. we saw it 11 months ago during the boston marathon bombing. they weren't telling their friends they were going to do a bombing at the marathon. they only discussed it with each other, as far as we can tell. you know, even their classmates after the bombing and after they learned who they were and they had done it, you know, are saying, you know, they were great. they never talked about it. all american kid. the younger one being captain of the wrestling team and going to parties and dating and smoking pot and everything else. they had no clue. there's no chatter then. there's no e-mails to other people or co-conspirators.

in the big plots, the 9/11s, you have a larger conspiracy and you will have the chatter of people bragging ant it or discussing it because they were in the know and want to talk about it. there's many explanations why there's not a lot of outside chatter with the case. >> some of the threats they are investigating now, two weeks since the plane disappeared. stick around. we want to talk about the possible scenarios and the new developments, the new satellite image taken by the chinese satellite. one of the issues discussed, it is in one of the most remote areas of the world. we'll talk about these situations when we come back.

ocean about 75 miles from where the other images of possible objects were seen. this is in a very, very difficult region posing very serious challenges to the searchers trying to find any confirmation of what these objects might be. alexander field has more. >> reporter: it's one of the world's most remote and punishing regions. >> the most inaccessible spot you can imagine on the face of the earth. >> reporter: massive waves and high winds, some of the conditions that hampers searchers in the south indian ocean for a sign of malaysian airlines flight 370 and the 239 passengers. more than 1400 miles off the coast of australia, the aerial search can last just a few hours at a time before pilots head back to refuel. >> that is really in the middle of nowhere. they are working with weather patterns that can hamper any

operation, any sea operation. >> a simulation that shows turbulence if the objects seen in three satellite images are part of the missing plane, the water conditions could push them further east and further aport. oceanographers say the objects could be anywhere in a 15,000 square mile area. that's roughly the size of belgium. below the water's surface, a murkier picture. the sea floor sits more than 9,000 feet down, deeper than most submarines can go. the mid ocean ridge rising from it making the search more difficult. >> the depth is a factor and the terrain. describe what it would like like down there. >> like the rocky mountains. >> it's hard to wrap your mind around what they are doing and how difficult this is. >> reporter: if the objects in the satellite images can be

found, if they are from flight 370, if researchers can use the ocean's currents to zero in on the data recorder, finding it among the peaks and valleys could be harder still. >> if it's in a deeper channel, it will be a bigger challenge. >> it will be dawn in a few hours over the indian ocean and searchers will be headed to the area where the large piece of debris was spotted by the chinese satellite. that area, so remote, so inhospitable to begin with, add it to the fact the conditions, they are deteriorating. jennifer gray has a look at the forecast. >> john, the indian ocean can be very unforgiving. it is an area known for very, very high winds, high seas, very rough conditions. moving forward as we go through the next 24 hours, we are going to see a band of showers move through. this is sunday, 10:30 eastern time meaning 10:30 p.m. you say so what, rain is moving

through at night. well, ahead of the fronts and the features, in the early afternoon on sunday, we are going to start to see the clouds increase. we are going to see the winds increase as well as the seas. so, that's going to make things difficult for searchers as we go through the next 24 hours. looking at the winds for the next 24 hours, we could see winds 40 to 50 miles per hour. then, they will start to slack off a little bit as we go through monday for most of the day. it is good news. when you look at this and look at the region, seeing winds of 30 to 40 miles per hour is not uncommon. that is a good day. this area is known for 40 and 50-mile-per-hour winds. the past couple days, things have been a little bit better than they should be this time of year, believe it or not. when we see winds at 40 to 50 miles per hour in this area, it with really not uncommon. the other thing we have been watching are the currents.

you can see the blue line to the south. a very strong current that is out there moving -- it can move an object one foot per second. that's the rate of the current. when you look at the search area, you say wow, it doesn't have to drift far to the south to get caught up in a current that is moving very, very quickly. yes, it's in an area where the currents aren't so bad right now. you have to keep in mind, when you look closer at the areas, we have eddies and smaller currents within these. yes, things can definitely move. look at the arrows illustrating the current. you have arrows in a circle this way, arrows going this way, arrows going this way and some going down. this is the object we are searching for. when you see the smaller currents in the middle of the ocean, it's going to drift all different kinds of ways, not to mention the wind is going to play a role, the seas are going to as well when you think about

the drifting. it is going to be very, very hard to find. time is definitely of the essence when finding out about something, three, four, five days later. itis that much more difficult to locate it. >> very difficult and very complicated. jennifer gray, thank you so much. appreciate it. ahead, the latest on the search for flight 370. the latest developments on the chinese satellite image. we'll speak to our panel of experts. russian forces pushing ukrainian troops out of bases by force. a combustible situation. we'll have the latest from the ground just after this. these are the messages in a bottle we have found. this is cool. it's from the '93 flood with a flag on it. a bunch of lottery tickets, i

we'll have much more on the search for flight 370 in a few

minutes. first, developments on the crisis in ukraine. the white house warning russia it will be responsible for troops hurt in crimea. this is what the white house is worried about. two more bases fell to pro-russian forces today in cry mena. they believe it could be the beginning. moscow says it's just for training. but no one right now giving russia the benefit of the doubt. we are joined by barbara starr. barbara, does the pentagon think russia is getting ready to move into more ukrainian territory? >> plenty to worry about. at the end of the week, defense secretary, chuck hagel called his russian counter part and bluntly said to him, what are your intentions? what are you up to? what are you doing with 20,000 troops heavily armed on the border with ukraine. he said we are here exercising. i have to tell you, behind the

scenes, the pentagon, the u.s. intelligence community, watching this literally around the clock. watching those troops because they are so close to the border, basically, all they have to do is essentially drive across. the feeling is the goal, if ordered, may be move into eastern ukraine and establish a land bridge between russia, across eastern ukraine and the crimea peninsula. it would give them the ability to reinforce and step up their troop presence in crimea. it's most interesting, john, after the developments today when the russians took over two crimean bases. calling for the russians to get out of crimea, saying you are there, we hold you responsible. >> you said the united states is watching and worrying. is the united states doing anything about this, working with ukraine to discuss the

possibility the russian troops could move over the border? >> it's clear the ukrainian government has a sense of what is going on. is the u.s. going to respond militarily? is nato going to respond militarily? everyone agrees there is no chance of that. so, more pressure on russia, you know, this is a situation that now is beginning to have so many dimensions because of this. the u.s. can no longer really work with russia on the question of syria and chemical weapons and iran's nuclear program leading to economic turmoil in europe and instability in that area. it's getting much broader, much deeper. the question now, will vladimir putin, the president of russia decide to move into ukraine, how deep, how far, what are his

intentions? i have spoke to sources in washington. they are watching carefully and have no answers yet. >> president obama traveling to europe this week to meet with key european leaders to talk about the situation in ukraine. any sense they will be providing further assistance whether financial or military to ukraine? >> there is, that's a good point, john. there is financeable and economic assistance throw organizations to ukraine. the u.s. and others providing non-lethal assistance, providing medical supplies, food rations, uniforms, that sort of thing. this is the situation that, you know, for all of the political rhetoric across this spectrum, i think it's fair to say vladimir putin know that is the united states and nato are not going to move in militarily. there's no indication of that. so, the question is, how far -- i think the question is, how far

does putin want to go, how far does he think he can go given this current feeling that no one is going to stop him anytime soon? how far does he want to carry this? >> there are diplomats in the state department and all over europe who would love the answers to those questions. thank you for being with us today. we are going to return to the search for flight 370. we have something interesting. cnn has audio of what the pingers aboard the missing jet would sound like if detected by super sensitive audio equipment. we are going to let you hear that after this. case, back to vacation mode. ♪boots and pants and boots and pants♪ ♪and boots and pants and boots and pants♪ ♪and boots and pants... voice-enabled bill pay. just a tap away on the geico app. ♪ huh, 15 minutes could save you 15% or more on car insurance. yup, everybody knows that. well, did you know that some owls aren't that wise. don't forget about i'm having brunch with meagan tomorrow. who?

welcome back. a new clue in the search for flight 370. here is what we know. a new object has been spotted in the southern indian ocean. a satellite captured this four days ago.

analysts released it this morning. it's 74 feet by 43 feet. what makes it more interesting, it was spotted 75 miles north of two other objects seen a week ago. search planes over the area did not find anything earlier today other than a wooden palette. they have been looking for the mystery objects for three days with no luck. soon, they are getting reinforcements, more ships and more planes headed to that area. crews continue searching in the so-called northern corridor. seven countries told investigators they did not pick up signals from the plane on their radar after it lost contact with ground control. so, when flight 370 first appeared, no one had any idea 16 days later, we would be wondering where it went with few concrete clues. for the families, that time has been a nightmare, full of false

hope, very real fears they will never see their loved ones again. jim clancy looks at what everyone is going through. >> reporter: so much ocean, so many questions, so little time. the mystery surrounding what happened to flight 370 with 239 souls aboard confounds us all. more than two weeks after it disappeared, police have no evidence, no motive implicated either pilot. country after country cleared its passengers. fantastic hijack theories abound, some worthy of movie scripts all are missing a leading man, an actual hijacker on board flight 370. >> often thieves get away with big heists. 777s would be worth big money in the market. >> reporter: back in the real world, time is running out. >> the first thing is underwater

location. a meeting only for certain days. that means it is almost already too late to have realistic hope of launching and the search based on those things. >> reporter: if the families haven't been able to get the answers to their prayers in the last two weeks, at least they are beginning to get the answers to some of the questions they had about their love d ones. but, it hasn't been easy. chinese women man handled demanding the truth after a week of promises, malaysia delivered some of the questions to high-level officials how family members may have died weren't easy on anyone. they needed to hear them. >> please, please. >> reporter: also desperate for answers, the media sometimes sacrificed dignity for a scrap of news. the longer the search goes on

without tangible evidence of what happened to flight 370, the more likely it will be the attention will turn to how the government or malaysia handled or mishandled the first 24 to 48 hours of the crisis. why did it take so long to admit the plane was missing? why weren't jets scrambled. why was their military radar doubted? as a result, almost a week was lost tracing false leads in the south china sea. debris, oil slicks, before the search moved on to millions of square miles in the indian ocean. hindsight is perfect. the search for the boeing 777 has been rife with human frailties. two weeks into the mystery of flight 370, it is still human of us all to hope. jim clancy, cnn, kuala lumpur. >> thanks. cnn obtained audio of what the pingers aboard flight 370 would

sound like if detected by a device used for locating sensitive sounds. they located it from the company they confirm made the pingers used on the plane. it's normally inaudible to humans. the company converted the sound for us so you know what it sounds like under water. take a listening. [ clicking ] >> doesn't sound like much. has to be so difficult to detect. then the pinger's battery life is designed only to last 14 more days. that's when it runs out completely and will get significantly harder for searchers to find anything, any traces of this plane that might be under water. let's talk to the panel about this. with me here in new york, aviation attorney daniel rose, in washington, an aviation surveillance engineer, tom is a cnn law enforcement analyst and

in denver, a safety analyst and author of "why planes crash." thank you all for joining me to talk about this. david, i want to start with you. we just heard those pings, what they might sound like underwater. there's also the word, the news of the deadline here now. just about 14 days until that pinging will stop. the batteries run out. how much pressure does that put now on investigators? >> it puts a lot of pressure on investigators, obviously, but also puts, i think, pressure on the faa. here is why. in that piece with tom clancy, he mentioned that ra that from the b.e.a. gave a talk there and what he recommended after flight 447 was the international community and the faa respond to that accident in extending the battery life of these pingers from 30 days to 90 days. there has been a tso, type

standard order, issued so all new pingers have to have 90 days. that starts in 2015. that's only for new pingers. there's no regulation forcing or mandating that those pinger that is are in existence now have to be upgraded. >> rick, we talked about the pingers, the length of time they run and the fact they need to be extended another 30 days. you feel in some cases, the technology we are using in general isn't what it needs to be. >> i pointed out the utilizization of surveillance that's pitched in the united states and the faa. there's a committee looking at it. they tend to spend a long time in committees and immediatings. i'd like to point out the transponder being shut off may or may not be factual. i have seen no previous track

data of a radar to read transponders in that part of the ocean. that's not unusual. in addition, cards being turned off may be normal. it's a fee for service. that company is located in maryland, recently purchased. you spend, for every message, you uplink. having it turned off is not unusual. it would be nice to know if it was continuely used by malaysian airlines in this particular route. i see no data to support that. >> tom, i want to talk about the latest development. the image taken by a chinese satellite that could be debris off the coast of perth, australia. now, we have a new image from a chinese satellite. talk to me about the difficulty of analyzing satellite intelligence. >> well, i think, first of all, john, by the time they go through thousands of downloaded photographs and then determine

they have that piece in one of the photographs, that's already four days. by the time they get it to the search authorities and come up with a new search plan based on it. it was lost, the item has moved with the winds and the currents driving it to another location in the ocean. that's difficult. of course, the resolution isn't enough to tell, is that one giant piece or several smaller pieces as suggested strapped together or the wiring of the airplane wrapped around it and makes it look like one big piece. all of that creates a challenge. they have had great search weather for the first couple days. the last couple days deteriorated to cyclone conditions. the next couple days are probably not going to be able to be searched. >> so many challenges. daniel, i want to talk to you about this. with all the technology, all the satellites in use, all the planes flying, the acting prime minister of australia says what is really needed, human

eyeballs. talk to me about the toll on these pilots, on the searchers taking that long 1500 mile flight over that search area. >> yeah, i mean they are the key to this puzzle, if it's going to get solved through the wreckage. you have the big picture satellite and the ships on the ground that are going to see the objects. you have to get the planes in there to narrow down the giant area and identify where that piece is. it's a huge toll for these guys. they are risking their lives. they are flying 1500 miles out there in the middle of nowhere. if something happens to their aircraft, they have few options. when we did searches in the navy, we had a term for it, it's blue water ops. you weren't going anywhere in terms of a land based runway, you were going back to the ship. but we had the ships. when doing the searches, we kept going back to the ship and relaunching. at least you didn't have the problem of having your own

malfunction while trying to help others find the wreckage in the middle of the ocean 1500 miles with not many options. >> people say, if you sneeze, you could miss the one chance you had to spot the one thing you need to see. >> absolutely. especially with the conditions we are seeing out there. the white caps, the waves, you can literally see the object and lose it the next second. >> thank you so much for letting out what is entailed in the search. it is not easy. next, it is designed to hunt submarines but can it help find flight 370? we go inside america's high-tech surveillance jet. that's coming up next.

if any plane can find flight 370, it is the po siden, the most sophisticated search plane. we got a rare, behind the scenes look. >> the ph surveillance jet is designed to hunt submarines. yet, when it comes to finding wreckage of the missing malaysian flight, the navy is not making promises. >> you don't know where to look right now, do you? >> correct. the debris may be very small. we are searching with small track lengths to make sure we

don't miss anything. >> reporter: we have been granted extraordinary access to a p-8 in flight simulating off the search of the coast of florida. it can see things no other aircraft can see. so much is classified we had to obscure parts of the monitor. there's sensors that extract heat and electrosensors. >> it's the best camera available on the market. >> what can you see with that that you can't see with radar? it gives it p-8 an advantage of picking out objects. the search area is so remote and take sos long to get to, the navy only has three hours a day to use the high-tech tools. that's not the only problem. there are so many unknowns that search teams really don't even know what to look for. it could be something as large

as a piece of a plane. but, it could be something as small as a seat cushion or a life vest. finding wreckage is like finding the needle in the hay stack. if only they could find the hay stack. >> that's a sonar buoy. >> correct. >> reporter: these devices are deployed in the indian ocean to monitor sounds and map the wind and ocean currents in hopes of narrowing down the search area. it has to fly in straight lines at 1,000 feet. at this height, a fishing boat can be obscured. this boat is about the same length as that piece of debris spotted on satellite. that could be missed, right in. >> absolutely. i would estimate it as 80 feet long or so. you can see the wave action today and the white caps, even

with that, that is a challenge. >> reporter: now, try to imagine spotting something smaller among the countless waves and reflectio reflections. keep in mind, this is a calm day off the coast of florida with 20 miles of visibility. the idea of finding a very small object in a big ocean seems almost impossible. remember, in the indian ocean where the search is going on, the seas are much rougher and the winds stronger. oechb though the p-8 is the best they have to offer, success depends on time and an element of luck. cnn, jacksonville, florida. >> we're going to talk about more on the search for flight 370. the challenges, the resources they have. do they have enough? we'll put that question to the panel after this.

allison started playing the violin at 7 years old. >> i played the piano and viola and guitar. they are the main instruments, yeah. >> at 16, a high school junior and student started to feel exhausted. then she has difficulty breathing. >> i couldn't perform every day tasks or remember how to dial the phone. >> she was misdiagnosed with bronchitis and then pneumonia. she was rushed to the hospital coughing up blood. she spent 2 1/2 weeks in an induced coma. >> they weren't sure if i was going to live. >> when she left the hospital, doctors didn't know what was wrong with her. >> i had a relapse. i was coughing up flood and i was sent to the cleveland clinic and i was diagnosed. >> it causes inflammation of the

bachelor's degree vessels. >> it took it's toll on me. >> depression, weight gain, they both followed, then the cheem therapy caused her hair to fall out. throughout several despite struggling with strength and endurance she enrolled at the conservatory, even played carnegie hall. she started violin for vas liets and plans to travel all 50 states tell herg story and performing to raise awareness and money for this disease. >> they have given me the ability to combine these things in my life in a way that i never would have thought possible. >> last october came an invitation to join the symphony. >> it's a goal i have had for a long time and it feels really, really neat knowing that i overcame all this and i'm still able to play.

welcome back to cnn coverage

of the search for flight 370. a few minutes to the top of the hour. we want to check in with our panel of experts to get the answer to the question so many people are asking right now. daniel rosen, one sentence, do you think investigators will find this plane? >> i do. i think on one hand time is on our side and that we have as much time as we need. on the flip side, the longer it it takes, the harder it is to get back to the wreckage. it's the worst thing possible for the families. >> rick, we're going on two weeks now. do you think investigators will find this plane? >> that's a tough one. i personally don't believe you're going to find it where you're looking for it. >> you think they need to change the search area altogether? >> i think simultaneously we should be looking to the north. i think the opinion you need to go after one piece of material were two large pieces floating.

you're still having things washing up on the west coast of the united states from the typhoon. >> i want to get tom's take. do you think investigators will find this plane? >> i agree with rick on that one. it's going to be really tough if they are not looking everywhere it could have gone. >> and david, you get the last word. right now they are looking off the coast of australia. they haven't suspended the notion of searching other pla s places. will they find flight 370? >> as committed as they are, i u don't see them giving up. >> they will keep on searching, at least using some resources to find any trace of this plane. it's been two weeks now since flight 370 disappeared. the news today, chinese satellites spotting what could be a piece of debris off the coast of australia. cnn's coverage of flight 370 will continue in just a minute. jim sciutto picks up with the latest on the investigation, stay with us. i was going to the library to do my homework.

you are in the cnn newsroom. i'm jim sciutto. we are following the latest developments in the search for malaysia airlines flight 370 and also on this story. confrontation in crimea, russian tanks crashed the gates and take over a ukrainian military base. we'll be live from kiev. first, in two hours as the sunrises on the indian ocean, fresh leads may reinvigorate attempts for flight 370. search crew cans will head out with several new clues in mind. i want to show you this image, a potential piece of the jumbo jet. a chinese satellite spotted this object floating in the search

area on tuesday. the object appears to be very large, 74 feet by 43 feet. the new object was spotted roughly 75 miles from possible debris that appeared earlier on an australian satellite image. and a visual spotter on an australian plane reported seeing several small objects including a wooden palette floating in the same area, just a possible clue. families of the missing 239 people on board are fraz led, exhausted, frustrated and demanding more from malaysian authorities. >> we are here. >> malaysian officials are promising to do more for desperate families. here's their response. >> i pledge to all the families wherever they are we will do everything to keep you informed. i will not give up hope and i

will continue as from day one, and i am given more hope to get closure to this by the support that we are receiving from so many countries. >> we have teams of reporters covering every angle of the global hunt for flight 370. we want to get you the very latest now and we're going to go live to the ground. international correspondent sara sidener, we're hours away from the crucial time of day, daylight breaking over the south indian ocean. the start of sunday's search. what kind of resources will be in the air today, particularly as we have this new chinese satellite photo? >> reporter: look, we know that there's also a cyclone in the area, so that may make things much more difficult.

almost all of the assets are in the southern indian ocean. the ships, most of the aircraft, 29 aircraft in that area are going to that area. so we know about these two satellite images. one from australia and one now from china. both are very important right now to the search. they sound like very similar size pieces. one of them 22.5 meters by 13 meters. the other one that australia reported, 23 meters. there's no telling if it's the same bit of debris. nobody knows that yet. the important thing that the debris is found. because once it's found, they will know, yes or no, whether this has anything to do with missing flight 370 that disappeared now 15 days with 239 passengers and crew aboard.

>> reading the daily report from the australian searchers, they say the planes in the air yesterday were in the same area as this new chinese satellite photo and didn't see anything. it's a big ocean out there, the weather conditions always changing and the currents move things. is that considered a discouraging sign? >> i think that what they have said that this could take a very long time. malaysian officials using the words "this is going to be a long haul." so it gives you a little bit of an idea that it is very, very difficult. they have to go square meter by square meter to try and find this. they blocked those out in blocks as far as they can go with as many resources. butt issue is when they have to fly to these areas, they only have about two hours because of flight time to actually search the area. and then they have to fly back and fly back again. so that is making things more

difficult. also the weather has changed. it was quite good, nice and still, nice and sort of like a glassy surface. much easier to see. then the cyclone shows up, so that is making things much, much harder for people who are in this search and rescue. but we do know that it's going to be difficult. no one has said that this was going to be easy. this is a vast, very, very deep ocean and in order to find these pieces, it's almost like finding a needle in a hay stack, jim. >> constantly moving hay stack, thank you very much, sarah. we're joined by david mckenzie. i wonder what the reaction is from families. a little more than a week ago we had the disappointment with the first photo that put the wreckage to the east. very close to where the plane lost contact. that turned out to be a false

alarm. is there hope or skepticism among the families? >> i think there's a great deal of skepticism. the families are raw with emotion. every day they get these leads and the leads are dashed wp with the image being released with an official state agency, we have seen that before, but china is putting more official word behind this. the foreign minister saying they alerted pretty quickly the australian authorities to look for this object. and as sarah said, they didn't find it out in that region today, but certainly the search will continue. the families, they are hunkering down through this period and very angry with malaysian airlines authorities, with malaysian government. they say they want the information and they want it quickly. it does seem that the authorities are trying to manage that process a little better asking the families to submit questions in writing. but in this stage, they don't want to do that. you have seen the angry scenes

through the days in the conference room here in beijing as family members really point the finger at these searches and the authorities because they just want some kind of clarity, some kind of closure in what must be an incredibly difficult time. >> no question, every day the uncertainty adds to the torture session for them. thanks very much to david in beijing. joining me now to discuss the latest developments, we have cnn aviation analyst unless a pilot himself, he's here with me in new york. safety analyst and author of "why planes crash" and peter bergen. we look at these images now. one of the big questions -- because this question came up with the first chinese satellite images more than a week ago closer to the place where the plane disappeared. and a lot of pilots were telling me these pieces are too big to be from a plane that hit the

water. what do you think when you see these images? >> i can't make that assessment until i have my eyes on it, but it's conceivable. it's very conceivable that it's a wing. my assumption is with the departure that took place with this wing or with the flight that the wing tanks, the center wing tanks were empty which would provide air space. they allow them to float. who knows at this point whether they are still submerge d. >> another pilot and analyst raised the possibility that this was rather than being one contiguous piece, it was a collection of pieces wrapped up in wire. you picture something hitting the water at that speed, you could have a collection of debris like that. >> yeah, sure, if it was still partially attached, but i think currents depending on the size of the pieces would throw it in different directions.

>> every day makes it more difficult. >> peter, want to bring you in. a lot of the latest clues are coming based on satellite data. the satellite pictures are grainy. we have to imagine they have been pixlated a bit to hide chinese capabilities. when you look at these pictures, what do you think of the quality and how much they indicate? >> it's a little bit outside my area of expertise, but we're still looking here for a motive. that's a very hard thing to ascertain, but it's interesting to me that we have had not only one very noncredible claim of responsibility from a terrorist group and now we have had nothing. so terrorism seems to be less and less likely, which leavehouse then with pilot suicide, which we have seen in the past. some kind of piracy motive perhaps, which also seems quite unlikely given where these

images are happening. and finally, some kind of motive which seems most likely. people do strange things. therefore, we have talked in the past about the turkish airlines flight. we're going to hijack the plane where he wanted to speak to the po pope. so it's that kind of motive seems to be the most likely now, jim. >> peter, that's what i have been hearing from intelligence analysts early on that they did not have terrorism on this. and they haven't seen one since then in the 14 days. they have been saying the longer it gets away from it if they haven't seen the sign, the less likely it becomes. as you looked at the possible explanations, terrorism looks less likely. i wonder, and i'll bring in the rest of the panel as well, as we look at the possible causes, the idea of a political statement, for instance, analysts have said

if someone wanted to make a political statement they would make it clear they brought the plane down, which was not the case in this case. when you look at mechanical failure, the longer we look at this, where are you leaning in terms of what's most likely? >> it seems to be that there's more evidence towards the mechanical. initially i had ruled that out simp simply because for this to have happened would be highly irregular with that aircraft. the 777 has three buss, every electrical system, any item within that cockpit can be transferred from one of those buss to the other. the other three generators, you have an external ram generator, you have so many redundancies that the opportunity or the chance that the transponder went out and then the akers went out and allowed it to be charged with power and continue to ping

against the radar, it would be a very, very strange scenario in my mind. nothing in my investigation history that i have seen like it. so it would have to be a really strange set of events to explain this from a mechanical perspective. >> i was speaking to a long-time pilot yesterday, and the subject of fire came up. the longest a plane has stayed in the air with a fire was 23 minutes before getting to the ground. so the idea of a fire and then the plane continuing on for hours and hours to him seemed farfetched. does that make sense to you. >> it. he was referring to swiss air, this we have been referring to a lot, i can see where he makes that assumption. s that 777. a different kind of airplane. we don't know if there was a fire what component started to break down. there may have been enough components to keep it level with the auto pilot so it's hard to

make speculation. >> comparing apples to oranges. peter, if i could come back to you before we finish up, and we'll have an opportunity to discuss this over the next several hours as we dig deeper on this, but when you look at a terror case still, or some sort of terror nex us is, as analysts look at this, they never want to close down a lead because you could get new information. they could find the wreckage and see evidence of an explosion. the intelligence community, explain how they would be sitting now. they haven't found clues yet. they want to keep the path open. they don't want to eliminate anything. how would a terror analyst approach this two weeks after the fact? >> i think the big advance, jim, is the chinese saying that they found no evidence of any of their chinese nationals having any kind of terrorist leanings or background. that eliminates a majority of

the passengers and the chinese take a very aggressive stance on the issue of terrorism originating from their separatist movement, which is the one group that might have a motive here. so once you have eliminated that, you're left with al qaeda-influenced groups, but it would be strange to attack an airline of a muslim nation, and then you're left with unknown potential terrorist groups or individuals. and they are unknown. and so you have eliminated the two most likely candidates based on motive and you're left really with not much. >> that's the confusion there and it really shows the importance of finding that plane. that will be the next big clue to get a sense of what brought this plane down. thanks very much to all of you. thank you for joining us. david, we'll see you again to

talk about this more. meanwhile, take a listen to this.

lot of people who are playing it safe and saying you just really don't know. we'll get to why in a second. looking at the images we have been talking about, they have to go out there and have to go inspect it. without any hard evidence to prove otherwise, this is something that they have to either prove or disprove. so the latest satellite image shows something in the water. it's estimated size of 72 feet. if mh-370 went down in the ocean, the size of the debris is really going to depend how the plane hit the water. if it was going at a high rate of speed and makes a nose dive did in 20 o 00 when it crashed into the pacific, in cases like that, you're going to get a lot of shatter. and it will be really like a shatter effect. there will be thousands of small pieces of e debris crashing into the water at that speed is kind of really like crashing into concrete. but if this was a midair explosion, much like twa flight

800, you may have larger pieces of debris and a wider debris field. the third scenario to point out for you is if somehow the pilot tried to make a controlled landing on the water, well the plane would break up in larger pieces. now what sinks and what floats depends on what part of the plane we're talking about and really what kind of material it's made out of. the metal pieces will go and sink. the engines are going to go straight to the bottom. the fuse l lodge is going to go to the bottom. but on day 15, there are some parts of the plane that would still be on the surface of the water and that's why they are taking a look at the latest satellite image. take a look at the expert as to what would potentially be on the surface of the water on this day. >> anything from the interior cabin should be still floating. most of the furnishings were made out of a variety of

plastics and some composite materials. things like the overhead bins, the seat cushions, the cosmetic bulk heads, all those typically should still be floating. in a lot of cases, they are going to be intermingled with wire and other debris, so you may have a lot of smaller pieces mixed in, which might look like a larger piece from the satellite or the air. >> so the bottom line is, jim, the longer the search goes on, the more scattered the debris field is going to be and the harder it is to track down that plane. >> and our aviation analyst just made the point at the end of a long flight when the wing tanks would be empty, that's a very buoyant piece of the plane. you have a lot of air in those tanks. just a possibility. and depends on the speed at which it hit the water. i also want to ask you about the pinger. this is the sound that searchers are listening for right now. we have an example of that sound

and the rhythm it makes. maybe we could play that again so our listeners can hear it. [ pinging ] >> it's a lot simpler than i was expecting. is that very simple kind of rhythm and click what i imagine the searchers are designed to pick up? >> right, absolutely. to be perfectly transparent, i thought it would be a louder sound as well, but that is it. and the manufacturer of one of these pingers, they were able to work with us to get that audio. but you hear how simple it is. and you hear how low it is. now consider the noises within the ocean, the crashing waves, you have animals that are there, wildlife that's in the water that's going to be making noise. you're going to have ships that

are in the area as well. it's competing with all of that. don't forget about the depth of the water. it make s it that much more difficult for this to be detected. add on to that, you can only hear it in a two-mile radius, so it's a tough job ahead. >> i remember seeing that some of the usa stral yan searches can see from the air flocks or herds of dolphins. and they make noise too, so you have these variety of noises. i'm sure the equipment is designed to do just that. thank you very much. coming up, we'll tell you why this robot could hold the key to finding flight 370 if the plane is indeed at the bottom of the ocean. plus russian forces storm a base in crimea. we'll take you there, live. cut!

we'll get right back to the new developments in the search for the flight 370 in a moment. we have to update you on something important going on in another part of the world and that place is ukraine. russian military forces today are taking whatever they want and going wherever they want with a piece of land they now claim belongs to russia.

as you hear there, shots fired in the air as armored vehicles smash through the gates of an air base in the crimea port today. a separate military base was also taken over and the ukrainian flag lowered in the process replaced with the russian flag. we'll go now to ivan watson in kiev right now. as we look at those scenes there, shots fired in the air, reports of a ukrainian soldier injured today, this is exactly the kind of dangerous and volatile combination of events that many were worried about as russian forces flex their muscle there. can you tell us how tense the situation is on the ground? and what's the level of concern there both in kiev and in crimea? >> reporter: jim, in the one case of this military air base, which was controlled by the ukrainians, we actually talked

to the commander about an hour before the russians made their assault. he said, listen, we're surrounded by pro russian militia and military units in the back of those civilian groups. and he vowed to fulfill his oath to his country, to his service. he said he was going to try to use fire hoses to keep the crowd back. then what clearly happened according to security camera footage feeding out remarkable live images was an armored carrier bashed down the gates and the russian troops stormed in. fortunately, there have been no reports of loss of life. instead what we saw was the humiliating scene of the troops having to bring their flag down and walk out of their barics with their belongings abandoning it to the russian military. that's a scene that's played out again and again, day after day at different ukrainian military

points across the crimeaen peninsula as the russian military has not only annexed that entire peninsula but is pushing the ukrainian military out from one base to another. it's really dramatic. there has been one loss of ukrainian life so far. a soldier who was shot to death while in his guard post in a guard tower. that was a couple days ago. >> we've been watching pictures as you were speaking of the russian carry iiers busting thrh the gates. it looks like an invasion, a military takeover. i wonder as discussions continue over gradually escalating sanctions against russia, what's the reaction of ukrainian people there? do they feel they are getting the support they expected from the europe and u.s.? what's their level of concern

now? >> it's huge. i mean i've been hearing for the past week talk of war. we have been watching ukrainian men of all ages signing up to either be in the reserves or in active duty in the armed forces in the national guard. the government has called up for 20,000 more troops in the armed forces. another 20,000 in the national guard. and i've been hearing the men who were signing up saying i have to protect my country from this enemy and the enemy they say almost all of them is russia. it's remarkable to hear that considering the close cultural, economic ties between these two countries that ukrainian men are saying, listen, we're going to have to defend our country about this much larger military across the border that has built up its forces right along the frontier creating such worry about the possibility of an invasion. as to support from western governments, certainly,

ukrainian government officials will privately tell you, yeah, they were hoping for more. they were hoping for tougher sanctions and more economic aid for this cash-strapped government. >> it's really sobering read, thank you. a reminder to our viewers, ukraine is right in europe. it's part of europe just to the eastern end and some real volatile situation on the ground there. thank you to ivan watson. satellite images of possible plane debris sparked hope. the hunt for malaysia airlines flight 370, but now there's the daunting task of finding those objects, spotting them from the air, days later. why this part of the ocean has made it so much tougher on investigators, right after this.

victoza is an injectable prescription medicine that may improve blood sugar in adults with type 2 diabetes when used with diet and exercise. it is not recommended as the first medication to treat diabetes and should not be used in people with type 1 diabetes or diabetic ketoacidosis. victoza has not been studied with mealtime insulin. victoza is not insulin. do not take victoza if you have a personal or family history of medullary thyroid cancer, multiple endocrine neoplasia syndrome type 2, or if you are allergic to victoza or any of its ingredients. symptoms of a serious allergic reaction may include swelling of face, lips, tongue or throat, fainting or dizziness, very rapid heartbeat, problems breathing or swallowing, severe rash or itching. tell your doctor if you get a lump or swelling in your neck. serious side effects may happen in people who take victoza including inflammation of the pancreas (pancreatitis) which may be fatal. stop taking victoza and call your doctor right away if you have signs of pancreatitis,

such as severe pain that will not go away in your abdomen or from your abdomen to your back, with or without vomiting. tell your doctor about all the medicines you take and if you have any medical conditions. taking victoza with a sulfonylurea or insulin may cause low blood sugar. the most common side effects are nausea, diarrhea, and headache. some side effects can lead to dehydration, which may cause kidney problems. if your pill isn't giving you the control you need, ask your doctor about non-insulin victoza. it's covered by most health plans. welcome back, i'm jim

sciutto in new york. the research for flight 370 is resume i resuming soon. so far we have seen four images. the first was the day right after the incident. vietnam released the image of something in the gulf of thailand. china followed with images of several objects in the south china sea. they turned out to be a false lead. the search then shifted to about 1,500 miles southwest of australia, the other side of the world, with these images released march 20th of objects from an australian satellite. and now this one seen by a chinese satellite in the same part of the indian ocean. my guest now retired astronaut chris hatfield who was on the space station for five months. he's also the author of "an astronaut's guide to life on

earth earth." looking at the search area, southwest of australia, it's closer to the antarctic than anything. this is kind of a dead zone of the ocean. so far away from anything. how difficult to search there? i know the weather was good yesterday, but they are talking about a cyclone coming through. what are some of the challenges down there? >> as you said, this is really the middle of nowhere. you're 1,500 miles from australia. you're 3,500 miles from antarctica. there working in an area where there's very little they can run to in the event they needed to. it's not a heavily trafficked area. it's not an area you really consider passing through or needing to go there except for this terrible tragedy, if that is the case. at the moment, they had very good weather, so they have a

time window. they are working against time. as people point out that the clock is ticking, we're 15 days into it. we have 15 days left to pick up the ping from the black boxes. and you have weather, which they are also going into a seasonal change. >> and also over time, floating objects could sink. >> there's a large possibility it could be ocean junk, for lack of a better word. unfortunately we won't know that until we have eyes at sea that are going to pick this up and identify it and let us know this is what we're seeing. >> i want to bring chris in. you have two steps to this. start with something seen miles above the planet and they send planes to get a closer look to see if they are parts of the plane. take some time to find those things. you've talked a few days ago at a conference about a fleet of microsatellites that could be released from space that might help in a search like this. tell our viewers more about

that. >> there are various ways to look at the earth from orbit, from space. the space station itself has some cameras, but it's just one eye in the sky. it only has one or two glimpses. but last month the space station deployed the first part of a whole fleet of small satellites. they are just not much bigger than a shoe box. there are 28 of them in orbit. they are just getting checked out because they are brand new. what they are starting to give us now is permanent eyes in the sky that are available just through a company in california through planet labs. once we get all 100 of them deployed, it's going to be a really good resource to see the world and look for small changes, look for debris in the ocean. maybe even look for an aircraft from satellite to satellite. so long as it's daytime and clouds rbt in the way, it will

be one of the best ways to see when we're looking for something like this. >> one issue with the search has been coverage because this is not a part of the world where a lot of satellites are focused. there isn't much down there. there's a lot of ocean. it's my understanding and i spoke to people that one issue with the clarity of the satellites is that these pictures are likely taken from an angle. they are taken from an angal and you don't get as clear a view. is that your understanding as well? >> if you go a little bit from the side taking pictures with the camera, if you can take them straight down, you only have a little bit of atmosphere in the way. as soon as you start tipping the camera up, you're looking through so much more air and distortion that it becomes harder and harder. not just with the distance, but to see the resolution of what you're looking at. so it's a really difficult place to see. i have flown across the indian ocean hundreds and hundreds of times in the space station. it's generally cloudy, very stormy, and it's completely

empty. it's a difficult place to see anything unfortunately. >> that map we just put up shows you, you have to turn the earth almost on its side to get a look at what we're talking about here. thank you to chris hatfield. we'll see both of you again in a few minutes to talk more about this search. while search teams from around the globe are scouring the oceans for any sign of flight 370, investigators back home are examining ways to keep this from happening again and one way would involve doing away with the famous so-called black boxes. more after this break.

much of the information about what happened to flight 370 is lost along with the plane and even if the plane is found, it could take years for the information to be recovered. could that be prevented in the future with new technology? we want to talk about the cloud. a plane disappears, you have to find the box whether it's on the bottom of the ocean or a jungle somewhere. meanwhile, my phone and my black berry are sending data all the time. why can't planes do the same thing? >> it is a very legitimate question. when you turn on the computer, your address book is automatically synced with everything else. part of the reason is cost. technically though, this is very

doable. it's something we should definitely be doing research on. especially when you think about air france, it took two years to find that black box. these contain critical information to prevent future accidents. it seems something like this would make a lot of sense. >> one reason they explore e these accidents is to prevent the same mistake from happening in the future. if you wait four years, or whoever many years, that's a lot of flights that have happened without that information. >> i know the concerns here are when you have thousands of airplanes in the sky, you have to get that data information, but from a technical standpoint rgs we're not talking about streaming video that's hundreds of gigabytes at a time. >> speed, direction, whether the engines are on fire. is that really an overload? >> that's barely a megabyte of data.

when you upload pictures to instagram, that's more data information going through the system than what they would be sending. i know there are some privacy concerns of we don't want our conversations in the cockpit heard at all time, but they are not listening unless there's a reason for them to listen. >> what was that channel when you were on the plane to listen to flight communications? >> listen to channel 9, you can listen to the docockpit and all the conversations with air traffic control. this is something that needs to happen. the technology exists and we should be doing it now. >> any sense of cost? i heard cost mentioned as a barrier to this. is this a major fix or as simple as putting a router on the plane? >> it would definitely require a satellite connection, especially for the internal flights. this is the same equipment they are starting to put on for in-flight wifi and streaming television channels to our e seat backs. >> that's important stuff.

it's an interesting point. we had a lot of conversation about whether you can make cell phone calls on planes, which requires a certain amount of investment. so here's something with safety in mind. >> and it would also have that side effect of now this you have put the satellite equipment to communicate data, now passengers can communicate data. >> i know from speaking to members of congress, this is already a change that they are look at as a possibility in response to this crash. i'm sure this is a conversation we're going to continue. thanks very much. we're going to drag you back again. thank you for joining me. coming up, we're going to focus on the 239 souls aboard that flight. their families in emotional anguish not knowing what happened to their loved ones. >> we aren't satisfied with the malaysian government's inaction. we have no information at all. they only say keep searching.

i just don't know where the plane has gone to. on my journey across america, i've learned that when you ask someone in texas if they want "big" savings on car insurance, it's a bit like asking if they want a big hat... ...'scuse me... ...or a big steak... ...or big hair... i think we have our answer. geico. fifteen minutes could save you fifteen percent or more on car insurance. still running in the morning? yeah. getting your vegetables every day? when i can.

family or friends in two weeks since the flight was lost. here now a snapshot of some of the lives so tragically interrupted. wife and mother of india is the secretary of the international collective in support of fish workers. she was headed to a conference in mongolia. her husband let cnn read the note he wrote to friends and family to thank them for this crucial support in this time. i remain focused on what we have at hand by way of information and stay with the knowledge that she is strong and courageous. her goodness must count for something somewhere. i carry faith that the forces of life are eternal, immutable and ever present to keep the drama ever moving. in the ultimate analysis i'm neither favored nor deserted. no one is. that's the end of that note. others were traveling on business. hollywood stuntman was reportedly headed home to beijing to see his two young

children and pick up material for a new project. paul weeks, a mechanical engineer from perth, australia, was on his way to a mining job in mongolia a father of two young sons. his wife told us he left his wedding ring and his watch behind in case of the worst. >> i had a bit of a car accident earlier on, actually just a year before. and sort of discussed what they wanted to do and for some reason before he left to go to mongolia, he decided to leave them both behind. he said that the oldest child should get his wedding ring and the youngest should get his watch if something happened to him. >> there were others on flight 370 traveling just for pleasure. this couple had been on vacation in vietnam heading home to beijing to their two young sons.

these were taking a honeymoon they promised for a long time. the loathens, two couples, four friends out seeing the sights together. and three americans were on board including phillip wood, an executive from texas and father of two. the other two with u.s. passports are young children. er brother and sister both under the age of 5. but it's not clear who they were traveling with. without waivers from the girls' families, there's nothing they can tell us about the children except they are among the 239 missing. let me get this straight...

satellite images and this could be another break. a visual spotter on an australian plane reported several small objects floating in that same area. families of the missing 230 239 people on board are frustrated and exhausted and demanding more from authorities. response to that, officials are promising to do more for the desperate families. here's what they had to do. >> we will continue to engage with the families. we are working hard with chinese authorities and the chinese working group to create a more conducive environment for the briefings. i have instructed my team to do a review of both findings so we can improve them. we appeal to all parties to be understanding during the extraordinary
