towed pinger locator. to this point, it has not been able to reacquire the signals. this are many steps yet before these detections can be positively verified as being from missing flight mh 370. firstly, we need to fix the position. then the ocean shield can lower the autonomous underwater vehicle bluefin 21 into the water and attempt to locate wreckage on the sea floor. another source of evidence search as wreckage would verify this lead. the area in which the signals have been received has a depth of approximately 4,500 meters. this is also the limited capability of the autonomous underwater vehicle. i need to be honest with you. it could take some days before the information is available to establish whether these detections can be confirmed as being from mh 370. in very deep oceanic water, nothing happens fast. of course, i will update you once we have an unequivocal determination. ocean shield will stay in its current area until such time as it can verify or discount the detections as being from mh 3

and has to be towed at about 3 knots. and so it can -- it can take a very, very long time to try and locate the wreckage. in addition, you have the acoustic anomalies that were described by angus houston's subordinates during the press conference. the pingers can behave in a very funny acoustical way in deep, deep water in which they're located. the sound signals can bend 90 degrees. they can be heard 300 miles from their source. they can be heard 20 miles from their source. so the pingers' battery dying would be a real complication here. >> sure. not to mention that the acoustic equipment can actually rebound, so to speak, echo throwing things off even more. so it is promising they were able to hold on to the sound consistent with the transmission of airplane black boxes for over two hours and then again pick it up for 13. how crucial is it for them to find it? because at this point they said they're trying to regain contact but have not been able to get those signals once again. are you there, sir? >> yes. i'm here. >>

here is why it is so critical to get that towed pinger locater deep down in the ocean.ger sound from the black box can get stuck in something called a deep sound channel. about 2,000 to 4,000 feet below the surface. if the sound does get trapped there and bounces around the only way to pick it up may be through one of these towed pinger locaters. >> seeing the device down there, that will put you in that channel so they can hear the pinger sound, or ricochet sound. the realtime, the scientists and technicians on the boat will be listening. >> pinger locaters have been used for years. in 1996, a tpl successfully located the black box for twa flight 100, in shallow waters off new york. investigators used one in 2009 when air france flight 447 went down in the atlantic but found nothing. if they have any luck locating the pinger from flight 370, next they will deploy this autonomous under water vehicle that maps the ocean floor. >> it will start to run patterns back and forth, shooting sound out the side and taking pictures. and it will show objects, shiny objects, basical

it towed and tethered on a line.lue fin 21, which looks like a torpedo, it will deploy on its own, it can rove around and it can go down to extraordinary depths. what it will do is pick up additional signals and it has camera capability, it can take images of the area where the pings were detected and it can scan the area of the bottom there. scan the entire area and go back and forth again and travel not just in a lawn mower pattern but travel in other patterns as well and send visual signals up to the ships on the surface as to whether there's wreckage or debris down there at all. >> okay, brian todd, many thanks to you to bring us the details on how that all works. very important part of this whole puzzle. and of course, you know, it's possible at this point that the submarines will be put in to motion as well. we know they are sitting on the sidelines. >> what i'm fascinated, rosemary, we have all these different pieces of technology, it's the most advanced technology and it's various nations putting all their we

sending its towed ping locater to the australian vessel.ore we get to the black box which could tell us what happened and caused the flight to end in the indian ocean, already how might what we've seen change in the aviation industry? >> that is a great question. i think you know, we're going to have to discover more on what got the airplane to this point. but just by mere virtue of the fact that we lost the airplane is probably going to put us -- with more data type streaming, more realtime so that we don't end up with the situation again. i mean, there are a lot of parts of the world including south america which i have flown on quite a few occasions that you lose radar contact. you are experienced. you know that this happens. sometimes the vhf frequencies, the normal radio frequencies we talk over are poor quality. so it is hard to change all that. but with the automation that we have, we should be able to solve those type of problems. and that is what will come of that. >> and les, it was fascinating what you were saying. the distance b

an australian naval vessel towing an american-made towed pinger locator has detected signals consistentbe coming from the black boxes of flight 370. one detection was over two hours long, one detection was about 13 minutes. and nic robertson, again who was with us from kuala lumpur, this detection was about 370 miles from where a chinese vessel had detected pings over the weekend. and this malaysian defense minister was asked about that. >> reporter: he was, and he dismissed it in a very cursory way. he said it doesn't matter if that debris that was spotted not far from where the "huisun" on friday and saturday picked up those pings. he said that the detection on friday and saturday were so far from the australian detection of today and yesterday. for him, the most important thing, he said, focusing on just finding those black boxes, identifying them. and an interesting question he was asked as well about when do you draw a line under this? and he really made it clear that his reference was going to be the families, but he was going to want to have that physical, the evidence or the bla

as they were towing that sensor.h that information, they could actually compute, likely very much compute an approximate position. i would guess that's probably what they did. >> is there any way what the chinese detented could be the same as what the u.s. navy detected even though they're close to 400 miles apart? >> you know, given the distance, it seems kind of unlikely to me that's the same signal, quite honestly. also, the equipment they were using looked on the primitive side. looked like a coffee can and string attached to it, so i don't know. >> bottom line is -- you're an expert on sonar. your sense is the u.s. navy really did hear the pinging coming from those two black boxes? one lasting for about two hours. one lasting for 15 minutes. the sounds coming from a relatively close location. it seems like that's the real deal, at least to me. >> i would trust what the u.s. navy and australian navy are providing us. i don't know what the chinese have found, but i'll go with what they're telling us at the moment.

>> we've got the towed pinger on the australian vessel. but hms echo, the british ship, also has some fairly sophisticated underwater search gear. and we've got a couple other devices that can assist with the search. which can be dropped from the air. in terms of towed pingers, i don't think we would be able to get another one in a hurry. these are in very scarce supply, and at this stage, there are no plans to bring another one in. >> so how much time do you think you have before the battery boxes die out? >> on best advice, the locater beacon will last about a month before it ceases its transmissions. so we're now getting pretty close to the time when it might expire. >> are we getting close to the point where a surface search is becoming futile and we need to purely rely on an underwater search? >> no, not at all. let me say that this is a vast area. a vast area, an area that's quite remote. you know, we'll continue to surface search for a good deal more time, because the break -- if we find a piece of wreckage on the surface or some ev

navy hydrophone or underwater microphone called a towed pinger locater.arch teams are counting on it to find the pinger mounted directly on the black boxes from flight 370. but time is running out for the pinger's battery life. >> what they're trying to do is get ears in the water while the pinger is still going. >> reporter: this is the sound it's listening for. the towed pinger locater, or tpl, is 30 inches long and weighs just 70 pounds. it's towed behind the ship that operates it, in this case the ocean shield, and generally moves at about 3 knots. that means with 150 miles or so to cover, just a sliver of the search area, it will take days. >> it does two things. it gets it down into that level. it also gets ate way from a lot of the surface not. wind on the water creates noise, propellers, dolphins, animals, fish, they all make sounds. >> reporter: the device can pick up the pinger sounds in depthing ranging from 50,000 feet from two miles away. here's why it's so critical to get that towed pinger locater down in the deep ocean. the block box can ge

the towed pinger locator has done all that it can do. this is the next logical step and this is what they are doing with it and this does have a lot of good capability but this is something that they've got to use at this point and it looks like they are about to deploy it in the coming hours. >> yeah. and brian, he wanted to manage expectations with this, talking about the depths here and also talking about flight 447 where he said they used every resource that was available to them at the time, even some of the technology that they are using now, like the side sonar, side scanner sonar and other submersibles and it took them 2 1/2 years to find it and they sort of knew the area where they were looking. >> that's right. they had a point to start with with air france 447. they recovered a little bit of wreckage. they had more clues to work with in that search. the towed pinger locator was also used and did not find the black box. it went right over it and didn't find it. officials at phoenix international say that's because the pinger be

this's why they have those two towed pinger locaters. one from the u.s., one from the uk, doing that 150-mile trek. they believe that's trperhaps where they're going to find that evidence that that wife says she needs. yes, they're not sure they're looking in the right spot, john. >> the words we hear now are luck and best guess. it tells you exactly where this search is right now. kyung lah, thanks so much. the panel joins us next to talk about this. also, tom forman shows us how the latest search area was arrived at. and we'll show you the high tech undersea tools that just started working today. and also, revisit some of the longest running disappearances in aviation history. stay with us. ♪ ♪ ben! ♪ [ train whistle blows ] oh, that was close. you ain't lying. let quicken loans help you save your money with a mortgage that's engineered to amaze. a seven day cruise to alaska or the caribbean from just $549. that's seven days to either marvel at mayan ruins... savor the very best local flavors... or sail in glistening glacier bay. with

, the only difference is it will be towed behind the vessel. giving you a realtime display on what the video could be seeing. and the second is the remotely operated vehicle. a vehicle that will have manipulators and we can lower that down and actually go through wreckage and look for the black boxes. and if we find them it will actually bring them to the surface. >> the pings were first heard over the weekend, being analyzed. at what point will the navy be able to say definitively yes, these are from black boxes, or no, they're not. >> i don't think you can say that it is. until we actually get a side scan down there and see debris on the ocean floor i don't believe that just from the towed pinger locator results alone that we can say with 100% confidence that we know that we're in the right location. >> have you ever seen with all of your decades of experience in this anything else that it could be? >> no, and that is what has got us wondering just what the signal is. but at the same time, we've also done searches where we have had no signals

it is pulling the towed pinger locater since then. that's four or five days. it has searched that area continuously through that period of time. this is what we picked up at the moment. you'll note that the most recent detections are all down in the southern part of the area. >> on tuesday, the two signal were acquired. >> okay. >> it was around 1,000 matters above the seabed, 3,500 deployed. >> is that -- experts say that is consistent with what happened -- [ inaudible ] >> it is quite possible that there's currents down there which could have disturbed the debre and also as it was falling from the surface it would have dispersed over a large area, as well. it has been said we know more about the surface of the moon than the seabed of the ocean floor. that's probably right. we don't have accurate sampling of the currents in that particular area. the indication we have that silt is on the seabed is taken from samples taken some years ago and 130 miles away from the current position. they are in a database that we can access but gives an understanding of how li

>> the towed locator pinger work continues.ave been no further contacts with any transmission. and we need to continue that for several days. right up to the point of which there's absolutely no doubt that the pinger batters will have expired. so it will be several days more. now, until we stop the pinger search, we will not deploy the submersible. is that clear? we will not deploy it, unless we find, unless we get another transmission, in which case we'll probably have a better idea of what's down there, and we'll go down there and have a look. [ inaudible question ] yeah. the issue is that if we can get more pinger -- well, more transmissions, we can get a better fix on the ocean floor, which will enable a much more narrowly focused visual search for wreckage. that's the issue. if we go down there now and do the visual search, it will take many, many, many days. because it's very slow, very painstaking work to scour the ocean floor. and of course, depths are very deep and it's very challenging.

has about 6,000 meters of tow behind it. it takes a good eight hours to do one full sweep. that includes three hours for the ocean shield to actually make a turn and turn around the other way. of course, as we know, every minute counts here with the black box batteries in danger of running out literally at any minute. i want to play some sound from captain mark matthews. he's leading the team that is running this pinger locator. >> what i'd like to do before i absolutely say with certainty that it is the aircraft, is one, reacquire the signal, two, deploy the underwater vehicle with the side scan sonar to map the debris field and then, three, switch out that sonar with a camera unit and take photographs of what would be the wreckage. certainly, we're jumping to conclusions here. we need to reacquire the signal to confirm it is the aircraft. >> yeah, the key word here caution, wolf, that's the message we keep getting in perth. >> clearly, the optimistic, cautiously optimistic, they may be on to the real deal. teams are also i

so, yes, indeed, they want to do more towing of this pinger locator.t's six times faster to locate it doing this than it is to launch the bluefin 21. which is also on loan from the u.s. navy which will go down to the bottom and use its side-scan sonar and/or camera to actually identify the wreck amount which we believe is on the bottom of the ocean here. >> geoffrey thomas, airlineratin airlineratings.com. thank you so much. overengineered like so many things, certified for 30 days, those batteries but maybe they can lost 40 days. >> excellent research. >>> more live coverage in the breaking developments right after the break. >>> this is cnn breaking news. >> the breaking news this morning, new signals detected in the search for missing malaysian airlines flight 370. overnight, investigators revealing two new transmissions heard from manmade devices they believe could be the vanished jetliner's black boxes. now the batteries on those black boxes could go dead any day. really any minute now. so this morning, the search is intensifying as crews scour th

i mean, a towed system is able to operate 24 hours a day and provide data in realtime.nd typically, has a coverage area around five to ten times greater than an auv. >> we have been talking a lot about this -- this area of the ocean, the depth of it, how inhospitable the ocean is. and we were thinking about the ocean floor, that it's never been mapped before. is it a reasonable goal, in your estimation, to map the ocean's floors, the way we have mapped and chartered our oceans? >> i think that's real possibility in the future. up until now, there hasn't been a great drive to map the ocean floor because, of course, as humans, we are really only interested in the little bits that which interact with so the ocean's been mapped mainly for navigational purposes, you know, to look for hazards to shipping. but now that we are driven by science, i think there will be a drive to go deeper and as battery technology improves, and auvs get longer range or we invest in deep towed sonar, then we will see more mapping of the ocean there are. >> are these deep towed sonar devices, are

>> a week ago, we were talking about how they had the tow fish, the towed pinger locater, they had it but they felt like there was no point in deploying it until they had debris on the surface to narrow down the search. we got so close to the end of the battery life of the pinger i guess they decide we might as well give it a go and lo and behold they are getting a signal. so it's kind of a one in a million thing unless there's some aspect to the search that we don't understand. that there's some other kind of information that the authorities have that we don't. in fact, i would go so far as to say, if this signal turns out to come from mh-370, i'd be very, very wondering if there was some other information behind it. because otherwise it's too coincidental. >> that from a writer very, very wondering. i like that. >> this is what this case has done to me. it has taken my words away. i have no more language. no can speak. >> could there be information we are not getting? except for last night, that i took off, we sit here and usually when the ships go out and as they hold the press con

there are auvs and towed systems. the navy operates a towed system called orion. >> and that's a sonar? >> it's like what we are seeing on the bluefin but it's towed behind the vessel and gives you real-time information. >> and other agencies have similar technology that could be used. why do we only have one of these devices in the water right now? >> well, that's up to the planners. when we finish the tpl -- and bluefin was brought in to do a tactical inspection. now as we move out of that sprint mode, we're going to get more into a marathon pace and things are going to be long, slower, and there may be much different equipment that is brought in. >> what is the maximum depth for bluefin-21? >> it's rated at 4500 meters but today the engineers -- we've gone through and looked at all of the components in bluefin and we're comfortable that we can exceed that 4500 meter limit at this point. >> do we know have deeper this water is? >> the chart told us it was at 4500. it may only be off by 100 meters. we're looking at,

on monday, i advised the towed pinger located deployed by the "ocean shield" had detected signals consistent with those emitted by aircraft black boxes on two separate occasions. i can tell you that "ocean shield" has been able to reacquire the signals on two more occasions. late yesterday afternoon and late last night perth time. the detection yesterday afternoon was held for approximately five minutes and 32 seconds. the detection late last night was held for approximately seven minutes. "ocean shield" has now detected four transmissions in the same broad area. yesterday's signals will assist in better defining a reduced and much more manageable search area on the ocean floor. i believe we are searching in the right area, but we need to visually identify aircraft wreckage before we can confirm with certainty that this is the resting place of mh-370. for the sake of the 239 families, this is absolutely imperative. today the "ocean shield" is continuing the slow, painstaking and methodical work to refine the location around the four acoustic detections. we are not yet at the point of deployi

navy being towed by the "ocean shield" and another being towed by a british ship. they are starting on one end of a 150-mile track and then they will converge upon each other and meet. it is frustratingly slow. they move three miles per hour. the u.s. navy says if there is a ping, they can hear it up to 20,000 feet away. it's extremely effective if they are in the right debris area. so, are they there? the u.s. navy captain in charge of in the dark. >> kyung, the families are increasingly angry and frustrated that malaysia, the government there isn't sharing information they want. >> reporter: what they really want is to hear the audio of whether it's the pilot or co-pilot saying those words, they want to hear the audio. they want to hear what that man said and they weren't allowed to listen to it. so we spoke to the partner of passenger philip wood. she sent us an e-mail statement. she writes, "it is impossible that this relatively sophisticated military power didn't see it. they are clearly hiding something. we just don't know what." she's talking about how the p

>> the towed locator pinger work continues. there have been no further contacts with any transmission. and we need to continue that for several days. right up to the point of which there's absolutely no doubt that the pinger batters will have expired. so it will be several days more. now, until we stop the pinger search, we will not deploy the submersible. is that clear? we will not deploy it, unless we find, unless we get another transmission, in which case we'll probably have a better idea of what's down there, and we'll go down there and have a look. [ inaudible question ] yeah. the issue is that if we can get more pinger -- well, more transmissions, we can get a better fix on the ocean floor, which will enable a much more narrowly focused visual search for wreckage. that's the issue. if we go down there now and do the visual search, it will take many, many, many days. because it's very slow, very painstaking work to scour the ocean floor. and of course, depths are very deep and it's very challenging. [ inaudible question ]

because if it is very bumpy on the bottom you cannot choose a towing sonar. you will have a lot of gap area where the auv is better. but if it is pretty flat or if the towing sonar is very good, they should have a map first. we started with the map, and when we had the map we said okay, we can use this. we had the orion on board, another rov, we had the remus, all the equipment, just when we got to the map we said okay. with all the equipment we know which one we have to use. >> should they be releasing at least some of the pictures what they're seeing down there? >> it would be nice for the families to see. but sonar pictures of the bottom is nothing. >> like a football field. you know? >> and i know you have gone over this. if they're scanning with sonar unless there is an anomaly in the way, they will have data. granted, it may be a little bit deeper but they have programmed it to go a little bit deeper. and the other towing assets if they do bring them in there, they will be effective. but they still will take just as much time as the auvs, they are not g

towed pinger locator heard those pings coming from what they suspect those two black boxes. that's where the entire search is under way right now. are you hearing the same thing there? >> reporter: well, we haven't had a statement from the jack, the joint agency coordination unit that's headed up by the australian retired air chief marshal to that effect, but, yes, i heard that wing commander from new zealand saying that. it makes sense, to be frank, in the sense that all along, the emphasis, every since the australian vessel recorded those pings that it picked up for a period of two hours, 20 minutes, the other for 13 minutes, ever since that acoustic event took place, the focus, in effect, has been on that area. it's the most sophisticated ship they have in the multinational fleet of ships looking for the plane. it's got the high-tech equipment on loan from the u.s. navy, and they've always felt this is the most likely spot where the plane went down, but they had to follow up on the lead from the chinese. i haven't got confirmation that lead is now being closed off, but i

. >> the towed pinger locator from "ocean shield" has detected a beacon of the black box. >> reporter: this is nearly 1,000 miles off the coast of australia where two sets of electronic pings were detected 15,000 feet, more than 4,000 meters down. the position needs to be adequately confirmed before this submarine is deployed to get a visual. >> this is being done without finding any wreckage thus far. and i think it's quite extraordinary. and what i'd like to see now is for to us find some wreckage because that will -- that will basically help solve the mystery. >> reporter: recent days have seen the search for the missing plane intensify. over the weekend, a chinese ship said it briefly detected electronic pulses in a different search area. chinese television showed the crew using a basic sonar device on a small rubber boat to pick up sounds. australian officials say the latest findings measured by the high-tech "ocean shield" are unrelated and the best hope so far for tracking down malaysia's lost plane. it could take several days before we get any real clarity on what has been fou

it's towed on cables like this. about three-quarters of a mile in each direction and go much deeper than the bluefin can go. many analysts believe if the bluefin can't find wreckage of the missing plane, this could be the next vehicle in the water. the bluefin-21 has scoured the search area, pushed the limits of its depth capability, and so far found nothing, but the ocean floor is deeper in some places than the bluefin can go and this may be the next best option. >> this is the orion system, the towed side scan sonar system. >> reporter: we got a look at phoenix international. the search team. the u.s. navy owns the orion. phoenix runs and maintains it. the project manager showed us the orion and the curve, a remotely operated vehicle that can recover wreckage. the orion can go deeper, can stay down much longer, days or weeks at a time, unlike the bluefin's 24 hours. it's towed with a cable, so it's not as bothered by rough seas caused by bad weather. orion doesn't have a camera like bluefin does, but does have sid

either on an auv, a battery powered torpedo-like device or a towed slid, a slid that's towed behind the, you know, because it can turn on a dime, and it's good for high resolution work because it can slow down and really focus. towed rays are better if you're looking for a large search area. able to cover between three and six times as much area per day. they're much cheaper to operate. and the key advantage is that they can work in every kind of weather, and provide data in real-time. auv, of course has to be recovered and downloaded and you see the data it recorded yesterday. >> anthony, how long could this take, this search? >> we believe now the search area will be narrowed dramatically, simply because the ocean shield, following this grid pattern search, is securing not only the strength of the pings, but also the relative magnetic bearing that they believe the pings are emanating from. the additional magnetic barings that they secure will help narrow the search area exponentially. i think there's an excellent chance, we're talking weeks or months, not years. >> david, we're talkin

we call that a towed array.aven't gone to that phase yet, because we haven't had that initial starting point. >> what happens when the batteries for those flight data recorders, the cockpit voice recorder, are dead, and the pingers -- the pinging is no longer going? where do the investigators, the search operation go from there? >> well, you see each day that the search area is shifting around. and that's because data that's being gathered from the aerial process, from the satellite process, and from reinterpreting the handshake data is being reanalyzed and reinforming the search area. so it's not game over if the pingers are not located. >> now some believe the plane may have actually gone in full, into the water, sort of like sully sullenberger's plane, miracle on the hundred dollars son, but then sunk. if there is a plane intact at the bottom of the indian ocean, how hard would it be to find that? >> if you know where it is, if -- if you know -- >> if you don't know where it is, a general area, obviously, but

. >> ocean shield is still in the area with the signals, using the towed pinger locater to try and find third signal. that process should take 24 hours according to houston if they are successful in finding a third acoustic event, and then they will deploy the blue fin 21. and underwater vehicle in the area to try to actually find physical wreckage. there's no physical debris being found. the authorities are saying that there's so many leads that were dead ends. but analysts are saying this has to be it. how did angus houston answer those questions that journalist saying that if it isn't the black boxes from mh-370, what could it possibly be? >> he did point to the fact that sound travels strangely in these deep ocean waters. so they want to be certain, he is insisting that they find the actual wreckage, and that will be verification that this is in fact, the missing plane. rosemary? >> and that is is certainly the next part of this investigation. it's just after 3:00 in the afternoon in perth, australia. thanks to you, errol? >> how are families of passengers reacting to the latest dev

she obviously has the towed pinger.t she also has a remotely operated vehicle which is highly capable. and we will see where it goes. and i'm sure as the commodore said, we're going to be looking at several hours, maybe, a couple of days before that one might be resolved. but as soon as -- let's say if that one completes without verification, it would then be tasked to go down to the chinese ship's position. and if in the meantime other leads come up, we will prosecute all of them. we will, you know, we will pursue these leads to their conclusion. >> [ inaudible question ]. >> well it's 24 hours. they're a long way apart, actually. 300 nautical miles. >> you cannot be sure about the signal frequency detection of "ocean shield". >> this is late-breaking news. i thought it was important that we -- we're totally transparent with you. i just want you to know that the search is a dynamic thing. things are happening all the time. and this broke this morning. this broke, what, an hour ago? and i thought it was very important t

they had to get a little wet this morning, this tow truck crew.ookup the car and pull it from the bay. it was an unusual tow job this morning after this crash. the driver he's okay. he was checked out or is being checked out at san francisco general hospital with minor injuries. he's an elderly gentleman from mountain view. they're doing a full investigation. they believe that this driver had a medical emergency possibly went into a diabetic shock and that's what caused him to lose control this morning and drive right into the waters of the bay. live this morning in san francisco alex savage ktvu, channel 2 news. >>> time is 8:05, a desperate coast guard search going on to try to find a missing 14-year- old boy who was carried away about i rip currents at ocean beach in san francisco. they're looking for 14-year-old march cosince about 4:00 yesterday afternoon. he was out there playing in the water when a rip current pulled him out to sea. the coast guard is still patrolling the waters from this area to the golden gate bridge. if it's not too fogg

now, the towed pinger locator, that is about 12,000 feet below the surface.elow 13,000 feet. even though the australian officials are looking in the right place there are challenges when they talk about the depths, three miles down in darkness with silt that can be very thick. a difficult environment to be sure. sad that we actually know more about the surface of the moon than the bottom of the ocean. so just how has the sea bed been mapped? gary tuckman has that. >> on the bottom of the sea, it is dark and mysterious. the video you're looking at was taken with an underwater camera during an oil exploration under the sea. but during the discovery, more than 9,000 feet down, a vessel that sunk during world war ii, spotted on the sea floor, the ship now visible for the first time in almost 70 years. the camera picture remarkably clear. but it was not the camera that originally spotted the wreck. it was sonar. >> so you can only see eight, ten, 12 feet at a time. with the sonar type system you could actually map much larger areas. >> david miller is the presiden

the next step in the search would be auvs or towed sonar.rs say they don't want the excess noise in the water from the auv. do you agree with that? >> it makes sense. they are going all in. they feel like this is their best chance to find these pings. they have located them here and there in an area of 12 miles across. it's not small enough yet. the batteries might still have a little juice left in there. so they really want to narrow it as much as they can before they commit the auv. apparently, the auv is a much slower way of scanning the bottom. it takes about six days to do what the towed pinger locater can do in one day. so if there is any hope -- if they go a couple of days without hearing anything at all, i think it will be time to cut bait and go for the auv. >> for the blue fin 21. how long could all of this take? >> it could take weeks, months and i'm sorry to say years. >> yeah. i think you are right. mary, obviously they are going to want to get every piece of the debris up, i would imagine. they are not going to leave anything.

the issue there is that the tipl, the towed pinger locator, is typically towed quite a ways off the seafloor go very far into the sea. it's one of the classic problems that we have. if you want to get a picture you've got to be close to the bottom. if you want to use sonar by listening or making a ping by the side scan sonar you've got to be well off the seafloor. you've got to do one or the other. we have done both and it's not a bad idea. >> let's go les. this one is coming -- people are wanting to know what happened in the cockpit. if pilots are both suddenly incapacitated in a catastrophic failure can other crew still get into the cockpit? >> i don't know how malaysia's cockpit door was configured but i can only assume the way they come out of the factory that there's a coated floor and the fight attendants would be able to get in through that coded door. >> it's coded. it's not like a key that you get into? >> correct. >> are they thinking about making changes when it comes to that at all because, especially in light of this, what if this was a pilot who, you know -- yeah, there's smog

you can see the tow truck driver just got here. he is about to put this car on all four tires.this car weighs about 1,500 pounds. the group who is doing this could face felony charges if caught. >> when i look at i, oh, my god, are you serious? >> reporter: it is not every day you look out your window and find a car tipped over in front of your house. it happened to garrett. >> i don't know who is doing it though. >> reporter: san francisco police would like to find out who is flipping smart cars in the city. the first call came in around 1:00 this morning. then police got another call at sweeney. brandon michaels saw it happen. >> i was just enjoying a cigarette upstairs. and all of a sudden i just see eight hooded figures walk out from the corner over here and walk up to the car. i thought they looked like they were up to no good. sure enough, they walk up to this smart car here. all huddled around it and just lifted up and set it on its hind legs. >> reporter: in all, four smart cars were flipped over overnight. police don't know if it is a horrible prank by a group of young

they are towed behind the ship.erence of temperatures and that could affect the propagation of the sound from the pinger. once you can detect it with the towed pinger locators, they run a course perpendicular to the one they detect on and the two lines of bearing and those will pinpoint accurately where they are. they have to know where the locator is so they know the cable and the depth. they have a pretty good accurate idea of where in the world that towed pinger locator is using gps. the next things is with side-scan sonar. the deeper into the ocean, the more pressure it gets and the beefier you make your systems. these pingers are rated to 20,000 feet which is about 98% of the ocean. if it went into some trench, which is deeper than 20,000 feet, those pingers will actually implode. when they go back to the next step of identifying the point from the pinger locator, to do a scan, side-scan sonar to verify how large and make sure it is aircraft wreckage and find out how large the debris field is and from that, the

only then do they really deploy the towed pinger locater so they can narrow down the search area. this discovery if it is indeed the black box that they've detected over the weekend, would be extraordinary because they did put the pinger locater in the water as kind of a last ditch effort, a shot in the dark as trying to find this thing, even though they didn't have a confirmed piece of wreckage and if it is, indeed, the signal, it would be a fantastic pull for this device. it does have some limitations. it can go up to 20,000 feet below the surface of the sea. it can detect the pinger locater from up to two miles away. but there are things that can obstruct it. under water obstacles like mountains and hills under water can disrupt it, bad weather can cause problems. as will mentioned, also, it has to make long passes. it takes hours to make long, slow passes over an area. that is a restriction as well. there you see the animation of the bluefin 21. that is not tethered as the pinger locater is. the bluefin 21 has more flexibility, it can go to great depths and it does map the deb

all of the cars involved in these latest attacks have been towed away.ou can see on the ground, the glass in this street here where one of the cars had the windows shattered. this all started around 1:00 when a smart car on the 200 block of anderson was found flipped on the roof. about ten minutes later, another car was found flipped on anderson and ogden. the last occurred around 1:30 a couple of minutes away in the portola neighborhood. a witness said he was shocked when he saw a group of about a half a dozen people in hooded sweatshirts walk up to his roommates smart car and flip it vertically. >> it seems like it's some sort of organized act against smart cars or a bunch of guys trying to cause havoc. >> reporter: all of the cars sustained shattered windows and body damage. we did talk to a sergeant. we were told that the incident is under investigation. we're live in san francisco. tara moriarty, ktvu channel 2 news. >>> 8:33. san francisco police investigating the death of a man hit by a car as he crossed the street. it happened about 11:00 last ni

. >> the towed pinger locator work continues. there have been no further contacts with any transmission. and we need to continue that several days. right up to the point at which there's absolutely no doubt that the pinger batteries will have expired. >> reporter: there's more high-tech equipment the search teams are waiting to deploy. like this robotic submarine which can scour the ocean floor. but first, they need to locate the signal again. australian officials say the search area has been significantly narrowed but still they are stepping up efforts in the sea and in the air to find more clues. >> we have a positive lead. today we have foreign ships and foreign aircraft over those sites. flat out trying to enhance that lead and to deliver something mo more tangible. >> reporter: but after a month, searching this fast ocean three miles deep, the hunt for flight 370 is proving a herculean task. wolf, it's been over 30 days since the search in that part of the indian ocean began. within the next few hours -- by the way, it's con

the towed pinger locator is only good while the black boxes are pinging.eally it's of not much value. so we want to maximize that while we have potential for the black boxes to still have battery life. maybe it's another day or two, but we still want to use that. once you get the bluefin in the water, the side scan sonar, there is really no limit for that. you can use that for an indefinite period. i would say there is really no rush to get that in. i know everyone wants to start getting you know, sonar pictures of the bottom, but if we take out the tpl now, we're really going to give up the last couple of days of any potential black box ping. so most likely we'll try to maximize that and get the side scan sonar in later. >> good evening, it is richard quest. let me reverse that point to you. you will keep using the tpl for as long as you can. but then how many days of no signal? no pings do you think would be appropriate before you can say all right, it's over, it's done, let's get it down there? >> yeah, that is really the question. and me here on sevent

you can put it on an auv or you can tow it through the ocean on a towed sledder and the advantage isey can be deployed very quickly but they have limited range. the bluefin might search something like 30 miles a day whereas a towed aray may search 100 miles a day. it's a question of scale. if the search area is going to be larger, you need more tools. if it's going to be confined to just the pinger locations, it could be small. >> bob, in your view, something can be learned from every investigation. this one is unprecedented. there isn't anything like it. everyone has agreed that they haven't seen this kind of mystery, ever. based on your opinion, the way the countries are coming together in the underwater and aerial searchers, what technology or lessons need to come from this and the capabilities, the tools that are needed to get to the bottom of an investigation like this quicker? >> well, i think that equipping the aircraft with a way to automatically transmit data to satellites is the answer and there are lots of different ways of doing that. it's going to involve some expense on

we can tow it about as quickly as a person walks. well, once you get the bluefin in there, it's actually taking a picture of the bottom of the ocean floor using sonar and cameras. so imagine walking but then every feet stopping to take a picture of the ground. so that is a much slower, more deliberate, methodical process. once that starts, we're in it for a good chunk of time. so we really don't want to start that until we have to. >> right. >> and anything we can do to even narrow this sector down even a little bit will be hugely beneficial for using the bluefin. >> now, commander, australia's prime minister tony abbott came out and said directly, look, he is confident that what you have heard so far is a black box from this plane. do you share that view? >> yeah, i do. for a couple of reasons. one is it was a -- we are detecting very continuous pings coming through in a manner consistent with exactly what you would expect from a black box. we've ruled out there was anything unnatural or anything from commercial shipping or anything
