without no consequences. that's scary. that's should be scary to everybody in the whole world. new hope and new mystery. day 31 in the search for malaysian airlines flight 370. as time runs out on the batteries in the black box, a chinese ship again hears signals deep in the ocean. and did the plane intentionally try to avoid radar? >> it appears essentially they're saying that whoever was flying the plane was trying to essentially disappear off the radar map. >> and cautious new optimism from families about the passengers. >> maybe this is a time, maybe for the next couple of days, next couple of months, next couple of years, we will find the enemy.

>> hello, everyone, and welcome to a cnn special report, "mystery of flight 370." i'm don lemon. right now searchers are racing to confirm two pulse signals detected by a chinese ship. they were heard outside the search zone, but followed the same arc that has been guiding searchers. adding to the intrigue, they match the same frequency as a black box pinger. another acoustic event was also detected by the australian ship ocean shield about 300 miles away. searchers are now working on borrowed time, with the black box pingers quickly rung out of juice. that's if they're not dead already. and as the search continues, so does the speculation about what happened inside the cockpit. a senior source inside the malaysian military say the plane may have steered a mysterious course. for the very latest on the search, we're going to go to perth now, the hub of the search

operation and cnn's international correspondent matthew chance. matthew, the ship hms echo now on the scene. but it won't be joined by the hms tireless submarine. tell us what is happening right now. >> yeah, well, that's because there are a number of different search areas, four search areas in fact, according to the british ministry of defense that are the focus of the ongoing multinational search operation at the moment. in two of those locations, they've got actual acoustic events that they're investigating. one of those is where the hms echo is and where the chinese vessels that detected apparent pings or some kind of pulses coming out on the same frequency, the beacon on top of the black box flight recorder would use. and that's one area of focus of this multinational search. another area is about 300 nautical miles away where the australian vessel the ocean shield is using its high-tech equipment to investigate another

acoustic event. so we shouldn't discount that either. but we may get some clarification in the coming hours, because within the past few minutes, it's been announced by the joint agency coordination center, the australian-led search teams, that there will be another press conference to be given in the australian city of perth within the next two hours. in fact, two hours from now. so hopefully, at that press conference, there will be some clarity on the latest situation, the latest status of this hunt for the missing malaysian airliner. don? >> all right. i'm glad you told us about that. do we know how many assets are being focused on the location of these two pulse signals and that one acoustic event, matthew? >> they're not giving us a breakdown like that. we know that there are about a dozen aircraft in the skies over the very large still search areas. that are scouring the ocean for

any more debris. and we know that there are at least 13 ships. plus the nuclear submarine as well that are in the search zone engaged in surface searches and subsurface searches as well. a bit of a tongue twister, that. but yes, so a very intensive search. and it seems to be intensifying as this kind of time pressure increases, because we have spoken such a lot about the battery life on those pingers, on the black box flight recorder and the cockpit voice recorder. time is rung out. but there is still a window of opportunity for them to get some kind of handle on where this airliner might be, don. >> all right. thank you very much, matthew chance. appreciate that let's go now to our panel this hour. cnn aviation correspondent richard quest, cnn analyst michael kay. collin keller, an integral player in the search for air france 447. and geoffrey thomas, managing

director of airline ratings.com. what do you know about this? >> well, before we get -- if we may, here we have the -- >> i know, but first answer the question, and then we'll get to that. because they're waiting to confirm that. what do you know about this? >> what i know about it is that we've known for a long time that the plane went north then turned to a u-turn, then went down into the strait of malacca, out to the west, and then across down into the indian ocean. you're watching it here. now we believe it's been confirmed or at least sources say that turn at the top was designed to in some shape avoid crossing malaysian airspace, at least crossing the land mass. it probably would have been caught on radar, but they do believe that that's why it was done. >> go ahead. >> yeah, i mean, just following from what richard is saying, primary radar goes out to about 125 miles around that. and the point here is that there is no definitive line which you

cross, which goes from being traced on a radar scope to suddenly disappearing off a radar scope. so it's incredibly difficult for anyone on that airplane trying to avoid radar to know whether they've avoided radar or not. and if you were going to do that, you would go the full extent and go 500, 700 miles off the coast to make absolutely sure and descend to make absolutely sure. we look at the track at the moment, and it looks fairly close to indonesia. so to me, if you're trying to avoid radar, you would have gone the other way and gone well out to about 500 to 700 miles. i'm a little bit dubious as to whether it would have been trying to avoid on purpose. if there were me, there is no rwr, radar warning receiver on this airplane. no one on the airplane knows whether they've been traced by a radar or not. so dubious. >> before we get to that, i want to make sure we can report it. it is confirmed. richard has new information. >> i was going to talk we're in this for the long haul. i have the press release from the jacc. >> go ahead.

>> we're in this for the long haul tonight by the look of it. it's 10:00 in perth. it's 10:00 on the eastern seaboard. media alert. the chief coordinator of the joint coordination center, air chief marshall angus houston will hold a press conference today monday 7th. >> in two hours. that's what matthew chance just reported that. i thought you were going with other information we're working to confirm. >> nope. >> regarding something else. but matthew chance reported in two hours. >> two hours. >> last night we had a press conference, as you know, richard. >> it's interesting. what he said last night is i'll come back to you in a few days' time. >> right. >> or when there is something else to tell you. so within 24 hours to come back means we're going to hear something tonight, i would imagine. >> let's move on. stand by gentlemen here. i want to go to colleen now. let's talk about the underwater search for the plane, colleen where the two pings were detected, could those pings be anything other than the plane? >> actually, i'm sorry to say they could be just about anything. i mean, i know that the box is

designed to ping at a certain frequency. that's pretty unnatural in nature, but that doesn't mean they could be picking upside tones from something else or anything in the environment. and without having any other parameters in addition to the frequency, there is other characteristics to the signal that would identify uniquely as coming from the box, it's really difficult to say exactly what they heard. unfortunately, from what i gather, they did not record it. >> paul? >> exactly. this is what we've been talking about earlier. the water, the medium through which the wave is transmitted can distort the signal such that even if the frequency is correct at the receiver, there may be some doubt as to what it is that they're receiving. >> and mary schiavo, you've been keeping abreast of the latest information here. you heard what matthew chance reported, that angus houston is going to give a press conference in about two hours.

richard quest also reporting the same information. could you think we're any closer here? >> well, possibly. i mean, the echo has been on-site now for the better part of a day. presumably, they went right to work. i'm hoping that at the press conference he gives us news of what the echo has been doing up there where the chinese ship found or heard with the hydrophone the pings. i'm hoping that the yate, and surely mr. houston knows that the whole world is kind of hanging on a thread to hear what happened there. so that would be my hope. maybe he is just going give us a count on which ships are where. but i think not. i think he is going to tell us what is going on up there. >> all right. stand by, everyone. next we're going to go to malaysia. we'll hear what investigators there are saying about news that the plane nay have intentionally tried to avoid radar detect. (dad) well, we've been thinking about it and we're just not sure.

(agent) i understand. (dad) we've never sold a house before. (agent) i'll walk you guys through every step. (dad) so if we sell, do you think we can swing it? (agent) i have the numbers right here and based on the comps that i've found, the timing is perfect. ...there's a lot of buyers for a house like yours. (dad) that's good to know.

an all-out search is back under way right now for the black boxes from the missing malaysian airliner. it's imperative those recorders are found to help determine what happened to flight 370, especially now that malaysian authorities believe the plane may have intentionally taken a route to avoid radar detection. cnn's jim clancy live in kuala lumpur now. you have been there since day one of this investigation. what do you make of authorities coming out now with their belief that the plane deliberately skirted indonesian airspace? >> well, they have said in the past they saw deliberate movements by the pilot in all of this. it adds detail to the record that this plane was trying to avoid perhaps not radar. it knew it would have to go, as

your guest said, 500 miles to do that. but it's avoiding the airspace. it's avoiding a reaction. it's avoiding an alert that would scramble jets or draw attention to itself. but there is a second thing that is important here. it more or less confirms what the inmarsat calculations say about the course that this plane took. why is that important? well, you know, those inmarsat calculations are based on something that was never meant to be a locator. still, it's given us an accurate record. and i think when you see that it's mapping the same course that we have here on the much more reliable military radar, you can say there is much more confidence in where they've mapped out the search zone in the south indian ocean today. that's what is really significant in my view. don? >> and, jim, as we've been saying, you've been there for weeks now in kuala lumpur. how are people there reacting a month later? still very few answer. >> very few answer.

but, you know, cnn assembled a team here. none of your competitors have anything close to the team that cnn has had on the ground on this story. and i'm not just talking about the numbers of people. yes, there have been more of them. but they've got a much greater depth of experience that has shown throughout the course of this story. if you remember all the way back to week one when two illegal -- two stolen passports were used, everybody else scrambled to say this must be terrorism. the cnn team knew well that 100-1, stolen passports are used to smuggle people, not used in hijacks, not used in terrorist acts. it's that kind of experience that has brought perspective. keeping reporting focused on what the facts are on the story. you know, you explore a lot of theories. and that's the discussion of the story. but as we're reporting it, our job is to give people the facts that we know and how they could affect the story. that's what we have pursued. calling for patience the entire time. not trying to leap to

conclusions to embrace theories. you know, that's been really the story here. because we've got a situation where an abundance of theories are colliding with a total absence of evidence on the ground. don? >> jim clancy circumstances thank you very much for that. up next, trouble in searching the ocean floor. it's three miles deep there we'll explore what investigators are up against, next.

welcome back, everyone. breaking news here on cnn. the man in charge of this investigation we're hearing about to hold a press conference. last we heard of him, he said he

would be back in consume of days. and now? >> yes. anxious houston, last night he gave a very full press conference in which he did discuss the chinese. he discussed ocean shield. and he basically said he would return when there was more to report. the fact he is coming back with in 24 hours, it could be nothing. it could be another update. but i'm guessing he is going to want to update us not only on the chinese pings, but also on ocean shield and the assets now being moved around. it will be a leap, don, to say at this point they're going to announce something significant. >> but we shall see. >> we shall. i ain't moving anywhere. >> stand by, everyone. the indian ocean is nearly three miles deep in the search area. the distance between where the possible audio contacts were heard 350 miles. not to mention waves, winds, and other objects in the hour. my panel is back. and i want them to listen to this. this is from david gallow with

the woods hole oceanographic institute. he said this. the oceans can do a lot of things with sound. for instance, if you know how to use thermal layers in the ocean, you can hide a nuclear submarine from some of the most powerful sonar. so for my panel, should we believe that the chinese reports of these possible audio contacts? that's perfect for you, mr. audio expert paul ginsburg. >> well, it's true that we have many different levels of distortion that can result from different depth, pressures, currents, obstructs, topography. and so i don't know that it would hide completely the pinging, but it certainly would make it easier, more difficult to pinpoint, that's for sure. >> but colleen keller, you said

it could be anything. in the last segment you said i hate to say it, don, but it could be anything. but at least it's something right now. and we've had nothing for so long. >> no, i agree. i'm thrilled that we're getting some detections. and i'm hoping one of them pans out. i mean, it could be that the crew of the ship that makes this detection needs to go straight to vegas and put their money down, because they're lucky men. but hey, if they get it, they get it. we -- the problem is, though, that we have two detections separated by 300 miles. one of them has to be wrong. both of them may be wrong. but they can't both be right. so it may be that this announcement coming out is just simply to explain the detections that have been made and explain that they're being investigated. >> go ahead, mike. >> i was just going to say, don, we know it's a pretty unsophisticated piece of equipment that detected this acoustic event. it was held on top of the ocean that was 4,500 meters deep. >> what do you mean, the microphone we see going in

there? >> yes. >> tim taylor made a good report. that's the video we see from the chinese of somebody putting a hydrophone in the water. but we don't know if it's the apparatus made to detect the ping. >> it's a point well made. if that was the case, should it be fairly easy to corroborate by putting passer sonar buoys into that area and then they would get a good sense whether there were ping there's or not if indeed they were hearing them from this unsophisticated piece of equipment on the surface. >> even from that very rudimentary piece of equipment, can you pick up ping from those depths? >> it's my understanding that the manufacturer says that we can. of course, another consideration is that we haven't heard about one piece of debris in any of these areas, although they could have floated or you know, be caught in the currents. but not one.

so it's very difficult. >> colleen, what are the odds? to get the black boxes before you even see one piece of debris, that is truly, truly out of the ordinary. that almost never happens. but what is ordinary about this particular case? >> well, i'm not going calculate any odds. it is very extraordinary. but i give them credit. they're trying, you know. you can't find anything if you don't have your stuff in the water. so i'm praying that maybe we get a hit here. >> yeah. up next, one source says the plane may have tried to avoid e detection on radar. can a plane hide in the sky? we're going to talk about it straight ahead. only gaviscon® forms a protective barrier that helps block stomach acid from splashing up- relieving the pain quickly. try fast, long lasting gaviscon®.

new information just into cnn. the joint task force in perth set to hold a news conference at midnight eastern. we're going bring that to you live right here on cnn. meanwhile, a fresh mystery surfaced today. a senior malaysian government source said that the aircraft may have deliberately securitied indonesian airspace in an effort to avoid indonesian radar. good weather is expected in the search area. and a few of the nine military planes are helping in the search in the air. three civil aircraft and 14 ships will assist in today's search. the race is on to find the pings coming from the black boxes before the batteries fail, if they haven't failed already. three reports of possible audio

contact have been reported now. still, no confirmation that they are connected to flight 370. so let's head back now to our flight simulator. cnn's martin savidge and mitchell cassado. >> the how is easier to explain than the why. mitchell has been working through the various way points. keep in mind we only know roughly the route he would have flown. we don't know the way points in order to make it happen. i'll let you explain because that's more your thing. >> yeah, how would it have avoided radar? it's a matter of looking at the charts, the maps, and seeing where the boundaries are for the airspace, the radar, and flying around it. >> so for your particular scenario, though, you actually plotted a course that takes it originally from what it was to beijing and came in a different way. what was it? >> this is basically our route

here. this magenta line, this pink line if we were going to beijing. what they did is a whole matter of turning the other way. so this is the line here. this is their course point opposite the direction they should have. and you can see -- you can see it here on the screen. >> you can see how the pink line deviates and deviates dramatically. >> exactly. this would be indonesia down here on the left. our bottom line circumvents it. gives it a wide berth around and down toward the south. >> we should point out that mitchell did this by reprogramming the flight management system. it isn't the only way that this could have been done. you could also have done by altering the heading, right? >> that's exactly right. so this knob here alternates -- takes the airplane on to a different head thang it's on currently. so all you have to do is turn this knob to whatever heading i want, press that button, and the airplane deviates. >> you can already see the plane is turning. that's the how you could do it.

but, again, you raised the real question, which is why did this aircraft, if it's true, circumvent or go around indonesian airspace? it certainly would imply somebody is in control. and if they're in control, then why would they do it? and it may hint at some sort of criminal act. >> all right. we're sitting here, as you guys are talking, and i have to tell you, i'm joined by my panel of experts. les abin, who is a 777 pilot is always wanting to weigh in on this. he was saying no way points, no way points. why did you say that? >> i think it's great what mitchell did. but what i was trying to get don's attention is do you guys think it's possible that by using heading select, it may have just very well gone by coincidence over the way points that are on the en route chart and not necessarily been programmed? >> absolutely, les. i think it's very possible. it's not -- there are so many way points around this place. it's not like it's hard to find a way point. so it's very likely they could

have accidentally hit them. >> i think always you can work in the fact that this could have been some sort of either human error, or just as mitchell points out, coincidence. it doesn't necessarily mean it was clandestine. >> hang on, guys, because a lot of people have questions for you. the panel here, richard quest, paul ginsburg, an audio expert, mary schiavo, of course a cnn aviation analyst, colleen keller, integral player in the search for flight 447. i've introduced everyone. >> the idea of way points, no one has ever said it did. this is the fascinating part. it's taken on a life of its own. once we knew that the route had changed and they had come back over malaysia into the straits, everybody then look at the map. and i think it was some journalist or newspaper article who basically said oh, look, it appears to be following way points. and then names the way points. and it's never been denied except the malaysians have said

there is no extra way points programmed into the flight management system. it only showed route up to beijing. >> martin and mitchell, you want to weigh in on that? >> well, i mean, as far as what we've done, yeah, we programmed in way points, and we followed way points. and richard is absolutely right. it is possible that way points had nothing to do with the rerouting of the aircraft. we use those because they're common means of navigation for aviation. >> yeah, it just makes sense in a big airline like this, you don't navigate with heading select. everything is you get a flight plan and you have way points. it just makes sense. it's counterintuitive to think heading select in an aircraft like this. >> i will say the malaysians have always at least early on in the investigation implied that this was a crime in their mind. and looking at something like this, you could interpret it to say oh, i see where they might

be coming from. but as we already pointed out, it doesn't mean there really was crime. >> and that's exactly what they do. they go through different scenarios. mary schiavo, you want to discuss more of this -- this flight path of avoiding indonesian airspace? what can this tell us if they were in fact doing that? >> well, again, it's the same information that we had on day one, but now someone's put a different explanation on it. and the explanation helps fill in some of the holes, but like we have often said, no matter how we explain things, there are always holes. but what this new explanation for the old data does is that it explains why there was no indonesian data -- radar returns. you know, initially we said, well, thailand, they didn't go through thai airspace. okay, they dipped down around thailand. and then there was no report of any radar from indonesia. and at first we said well indonesia didn't cooperate and give it. and now we learn that indonesia

said they don't have any radar points. so this hypothesis explains why there may be nothing, no radar from thailand and no radar from indonesia. but, you know, then somebody has to have put a motive on it. so we don't know the motive. the motive might have been skirting radar, or the motive might have been they were just flying in a certain direction. and we don't have the radar to clearly plot it around indonesia. however, if that's what the chinese were thinking, and that's how they replotted the plan as to where to search, it would be very interesting to see if these pings turn out and if they use this skirting the radar idea to find their place to search. that would give it more credence to me. >> colleen keller, does this -- the intention here would seem that someone -- by saying that they skirted indonesian radar, what have you, some sort of

criminal intent. that's the implication. >> well, what we're doing is we're looking at empirical data. we're looking at where the aircraft flew, and we're trying to guess what the intention is from that. and that's always dangerous territory. i mean, you really just go back to the data. we know where it flew, but we don't have any other evidence that suggests they're trying to skirt radar. so i'm not willing to draw any conclusions from that. >> and as an audio expert, none of this says anything until you want to get the empirical evidence, which is if the plane is on the bottom of the ocean with the plane on the bottom on the ocean. >> show me the ping. show me the ping. that's when everything changes. >> yeah. >> and by the way, as an aside, i'm sure the viewer has noticed that each time we go to the simulator with martin and mitchell, there is quite a bit amount of noise. and that's because, i guess, that the -- they're making the

simulator realistic with the cockpit noise, whereas in an actual flight, both pilot and copilot would be wearing noise cancelling microphones and full headphones. >> right. >> so they would be able to hear each other as well as the tower very clearly. and it would block out most of that noise. >> but the noise that you're hearing would still be part of the recordings that you would retrieve from the airplane and could give you information as to what happened to this airplane. >> exactly. that would come through what we call the cockpit area microphone, the cam. that's another channel that is recorded on the cvr or cockpit voice recorder in addition to the pilot and copilot channels. >> right. so we were trying to figure out, les, you were saying by just listening to the tower recordings, right, it would be hard to distinguish the pilot from the copilot. even your own wife can't tell your voice when she is listening. >> correct. >> sometimes when you're

listening to cockpit voice recordings, it would be the same thing. but they're on different channels. >> correct. there is a lot more information recorded on the cockpit voice recorder than can be gleaned from listening to the single challenge received radio signal to the tower. >> yeah. do we have, producers, if we can, the sound of the pings and the chirp and the tone that paul ginsburg supplied for us earlier? i think our viewers would like to hear that. because we're trying to figure out, we have been trying to figure out throughout this whole thing if in fact what the chinese ships and the australian ships have picked up if it is in fact cockpit voice recordings or the black boxes that are presumably on the bottom of the ocean. and you're saying these aren't the exact sounds, but these are sounds that they would be looking for, similar sounds. first let's listen to the pulse tone. [ beeping ] >> that's the pure tone.

>> and you said that one is, paul? >> that's the pure pulse example. a single frequency for a burst of time, 2/10 of a second repeated every second. this is just a demonstration. >> and then you said there is another one that is a chip it can be programmed as well? >> this is a chirp where we have increased the frequency during the transmission. and you can see that it has a different wave shape. [ chirping ] >> and sound. >> so they're listening for anything that is similar to those two sounds. and if they had the same characteristics of either of those two sounds, depending on how the voice recorders and the cockpit recorder, depending on how they were programmed. >> exactly. >> then you would know if it's a signature of that and not just some -- something that happens to be on a similar frequency. >> that's correct, exactly, exactly.

>> no questions? >> no. >> everyone agree? >> my question to paul would be what is the receiver -- they're getting this on receiver. so you wouldn't actually hear this -- would this be something to the human ear? >> that's interesting. you said you can hear it, but it also has a visible -- >> well, you can hear my example. my example was one thousand cycles, well within hearing range. but in actuality, we're looking for something that is about double the human's highest limit of hearing when you're a baby. and it decreases after that. so you would not hear it. but you would see the wave form on a specialized receiver. and if you incorporate filters to mask or minimize any frequencies that are outside a certain band centered on what you're looking for, it will

enhance your reception. >> that's why he says, les, here is a thing that says shape of the pulses. because if you can't hear it, then there is a certain shape whatever the instrument that is picking it up. >> i wanted to get a visual picture what these folks are doing with all this instrumentation. they're not actually hearing something. they're more than likely looking at a visual. >> they're watching it. that's right. >> and you put together, there is another -- i don't know if you have another graphic that you put together. and it's got the one with the green lines. what was that one? what is that all about? >> the two wave forms. >> yeah. well, that's a wave form that we saw. >> this is actually -- >> i don't know if we'll be able to pick that up because it's so faint. >> it's going to be difficult. >> there is a graphic. >> the top one is a sort of wavier. >> this is a single frequency. >> right. >> and then this one you can see that the period or the distance

between each successive cycle gets shorter and shorter and shorter as the frequency increases. >> right. >> and that's the difference between a pure tone and a chirp. >> but the thing here is the longer this goes on, the weaker all of this gets. and the chances of hearing it grow slimmer and slimmer with every single second. >> sadly, yes. >> we'll be right back right after this. don't go anywhere.

31 days and still not a piece of milling malaysia airlines flight 370 has been found. no a wing, not a piece of luggage. and certainly not either of the plane's critical black boxes. many of the passengers' families are returning home to beijing, frustrated at the pace of this investigation. cnn's david mckinsey joins me now from beijing. david, what are the families saying? >> well, don, 31 days, you're right. i've been here from the very first hours from that initial shock of those families. now the shock has sort of turned into frustration, as you say, and also, just exhaustion. on this latest set of news that could provide a promising lead, the opinions are varied. but most people we've spoken to want more information.

>> maybe this is the time. maybe for the next couple days, the next couple of months, the next couple of years we will find the ending. but there will be a time that it will end. so to me, i don't want that it -- but if i have to phase it. >> it could be true, because the area is where the plane should be. it's so strange that there was no emergency beacon signal. i think the plane glided on to the water and sank so the beacons weren't activated. >> well, you can see that people are stealing themselves for what is a very long process. and the family member, many hundreds of them in fact stuck here in beijing and around the region are hanging on to every bit of information. but really, they want some concrete answers so they can get on with their lives.

at this point they're in this limbo, don, that they just cannot get out of. don? >> everything now is a maybe, a possibly. we've heard this. we've got to check it out. we can't confirm. but are they -- are they at least encouraged by the arrival of the british ship that can map the ocean floor? >> well, certainly they want to have no effort spared on figuring out this mystery. because it has very real consequences for them and their families. there is a variety of reasons they want. one is emotional, of course, because anybody, it's human nature to hold out hope. i think at this point, 31 days after day, they obviously fear the worse. but they want to start the grieving process and get on with their lives there is also very real consequences. because if they can find the data recorders, the black boxes, then they can start establishing why this happened there could be multimillion-dollar lawsuits involved here.

and they're already lawyers here in beijing talking to family members on a daily basis. if they cannot find any evidence on that plane, then those lawsuits are out of the question and certainly the families have fewer options. but, again, right now they want to take that first step. we haven't even reached that first step that they want to actually get some closure. there are so many steps after that. but just taking that first step has to happen. don? >> david mckenzie, david, thank you very much. i appreciate you. next, our experts answer your questions about the disappearance and the search for flight 370.

as richard quest said, we're in it for the long haul because at midnight eastern time here in the united states, the man heading this investigation will hold a news briefing. not sure exactly what he is going to say, but every time he speaks, it is something of importance. we will carry that live. we're following new developments in the search for malaysia flight 370. right now a british ship headed to the area where the chinese say they heard pulse signals on two consecutive days. let's bring in our panel. richard quest. bill wants to know. this is a viewer question. bill wants to know, are you sure the chinese pings were detected with that hand-held unit? surely they have better tech than that. >> bill, an excellent question.

and the short answer is. no we are not sure in any shape or form. those pictures came from chinese television, cctv. the experts say it would be difficult. i think they're being polite. privately they'll tell you it's just about impossible to use a hand-held device to get it. and if you look at the still photographs, look that. they're using ipod and headphones which i'm sure has given people like yourself a conniption at the mere thought that you would use those to actually listen. >> i think we should let the expert weigh. in paul is an audio expert. >> well, paul, weigh in by all means. >> well, i agree. obviously, if we're trying to listen to something, we want to be as close as possible to it. and from the surface, knowing that the depth is three miles or more. >> about three miles. >> then it's silly to think that

that's the best that we can do. >> would you use those sort of headphones, little in-ear headphones? >> no, no, no. of course not. >> you heard them earlier saying they're looking at signals rather than hearing them. they're looking at waves. >> they may be able to convert a received signal to an audible signal. so what they're listening to is derived from a signal. but under any circumstances, you would want something with quality. and that would mask the ambient sounds of a moving ship. >> just to make the point though, to bill, what i'm not saying is that the chinese don't have extremely sophisticated technology. they do. >> we just don't know. >> i have no doubt they've got it up the wazoo. we just don't know what it is. >> they're not showing it. >> those are the pictures that we're seeing. but is that what they're using to pick up the pings?

we don't know. probably not. les, let's have you answer this one. this is from jojo wants to know. can ocean shield also deploy men in small boats with portable pinger detectors like the chinese did? well, we're not sure the chinese did anyway. but go ahead. >> listen, that's not my sorry of expertise. i'm not going to touch that one. ask me some pilot stuff and i'll try to answer that. >> mary schiavo, mary, you answer this from joe? can ocean shield also deploy men in small boats with portable pinger detectors like the chinese did? hang on. we can't hear mary. did we get mary yet? nope. no audio from mary. sorry, mary. so anyway, you choose not to answer that question. >> yes, sir. >> you stick with whatever. so as i said, we don't really even know if that's how they're picking it up by deploying the men in those boats.

lastly, why was the chinese vessel searching in an unplanned search area? that's the question that everyone has. >> last night, angus houston addressed that. he addressed it, and he basically said it was part of the search area in terms of the general search area. he skirted it. and then he went on because a journalist specifically asked the question, not to put too fine a point of this, are you and the chinese at disagreement? and he said again and again, no, happy with the cooperation, happy with the information. had dinner with the ambassador. everybody is getting on very nicely. and we're bringing in an extra chinese speaker. >> mary schiavo is no longer at a loss for words. i understand that we have her now. mary, you want to answer that question for us? >> sure. the ship has the towed pinger locator. so it has the proverbial big

gun. it also has small boats, launchables, zodiacs or probably some rigid hulls. but because it has the towed pinger locator on the hull, it doesn't have to put the small boat, in but it also does have small boats. >> i thought this was another question too. in the press conference last night, i'm sure you heard some of the press conference. why was the chinese vessel searching in an unplanned search area. it was kind of in the search area, but it wasn't. angus houston addressed it and kind of didn't last night. do we know what is going on here? >> no. we can only have hunches. for the information to come out about they think it was skirting the radar, the plane was securitying the indonesian radar, one can only assume that perhaps the chinese were coming to their own conclusions about where it might have been, and who knows what else they have in terms of coverage of the area. i just thought it seemed highly

unusual that you would kind of guess, put your finger in the air and say i will search here and you get pings. so i'm a little suspicious that it was just a lucky break. i think there is science behind it. >> ah. >> there you go. from the professional, the woman who knows who has investigated many of these. i think you said something very interesting here, paul. mary did. there is the big gun that has the towed one and then are there are smaller units out there. richard raised the question. would you be using the little headphones and sticking the thing right there? >> i would think i would want to use the most powerful, most sensitive, most selective. >> equipment. >> receiver they could get my hands on. >> yeah. >> and then track back and forth. make a chart of the received signal. the problem is we don't have that luxury given the batteries about to be depleted. >> we're getting close to the top of the hour. you're right.

we're going to be here for a long time this evening because a lot could happen between now and midnight. a lot may happen after that once we do hear from the man in charge of this investigation. we don't know what he is going to say. but he has called a news briefing to be held in just about one hour from now. welcome, everyone, to a cnn special report, "mystery of flight 370." i'm don lemon. the joint task force heading up the search for missing flight 370 has just announced a news conference. this unplanned briefing is set to take place at midnight eastern time, in just about an hour. and we're going bring that to you live. so right now, though, we want to talk about for the first time we have what could be the sound from the plane's black box. search crews are scouring the indian ocean, trying to find out if there is anything to the pings that they heard this weekend from chinese ships, from a chinese ship. a specially equipped ship that

has now arrive at the spot where the two pulse signals were picked up. on board the hms echo high detection gear. just north, just north-northeast of there, i should say, the australian ship ocean shield is continuing its investigations, trying to figure out the source of a curious, quote, acoustic event. and today another question is emerging. did the plane try to avoid indonesian airspace? a senior malaysian government source has come out with an explosive allegation that flight 370 apparently steered a suspicious course to avoid indonesian radar. and for the latest on the search, i want to go to perth, where the news conference is soon to be taking place, and that senior international correspondent matthew chance. so matthew, do you have any clues as to what this impromptu press briefing may be about? >> not really. i mean, i've spoken to the press office there, and they've said

it's just an update on the status of the search. you know, but, it feels like it could be a significant development. it feels like after the experience of the press conference yesterday when such a lot of detail was given, that it's going to be well worth, you know, kind of listening to. it's going to be given by angus houston, who is the retired air chief marshall here in australia that is heading up the multinational effort to look for that missing malaysian airliner. you know, remember, don, there are two main areas of focus at the moment. the one of them, perhaps the primary one, we don't know, where these chinese ship or this chinese ship detected a pulse from under the surface using their equipment and where the british vessel, the hms echo is now headed and has now arrived and has now started also to try and look for some kind of pulse with its high-tech equipment underneath the surface of the indian ocean. but there is another area as well, which i think we shouldn't

lose focus on, which is that ocean shield, that australian vessel, which has been described as the most technologically advanced vessel that there is in that multinational fleet looking for this missing malaysian airliner. it has that bit of u.s. naval equipment that it is towing along the back, the tpl, the towed pinger locator. and that's a very significant, very sensitive bit of equipment. and that is monitoring what it describes as an acoustic event as well. hopefully at this upcoming press briefing in an hour from now, we're going get some clarity on what the progress has been in both of those two areas, don. >> okay. so they honed in on these specific areas, saying that yesterday in the press conference, and matthew, you were here last night, they were saying that they sort of reconfigured some satellite information and then corresponded it with where they saw the sounds. and that sort of changed the search area. and also, angus houston said that's when he moved certain

assets into the area of these possible pings, matthew. >> yeah. i think there were a couple of factors at play, to be honest. that was definitely one of them. perhaps the prime factor, that they had recalculated or reassessed the original satellite data that they received. and it shifted the emphasis or the priority of the search towards the southern area of the search zone. it just emphasized the southern part of that search zone as well. in addition to, that we had these reports coming from the chinese media initially that that chinese ship, the hixin the two events two kilometers apart separated by 12 hours as well that was another possible clue that had to be investigated given the intensity of the moment and the time pressure the search operation is under. so yes, they moved their resources, their assets significantly because of those two factors, don.

>> thank you very much. i want to bring in our experts now. cnn aviation analyst mary schiavo, colleen keller, and cnn aviation correspondent richard quest and les abin. and audio expert paul ginsburg joins me now. mary, what do you make of this unannounced press briefing? >> well, i would like to be optimistic and say that since they deployed the echo up to where the chinese had picked up the pings on two different days that they have an update for us and say they have put their equipment in the water and they're listening. and either they heard something or they haven't. and as the previous guest mentioned, it would be nice to hear what the shield is doing. i mean, surely they know that the world is waiting for the next ping. that's what i hope we hear about. if they've got any new news to tell us about the sounds from

the deep. >> geoffrey thomas also joins us from airlineratings.com. geoffrey, you're in perth. angus houston is there. perhaps you have some information that you might want to share with us before he comes out and gives his press briefing? >> yes, don. look, there is a sense that this announcement may have something to do with what the ocean shield has found or not found. the sense is that possibly it has found something or it has reconfirmed what i've found yesterday. approximately 12 hours ago, sorry, 24 hours ago, it located an anomaly, an acoustic event and it was left in the area. there is a bit of a sense that this announcement is going to relate to the ocean shield, whether it's actually found something or not. and maybe, maybe it has. maybe it has. >> yeah. we'll see.

again, i think what is important and what is interesting here is that he said i will come out and brief you within the next couple days, he said, or when i get something new or worth telling you. richard quest, you picked up on that. we were both listening to him last night as he gave the press briefing around this time. >> it wouldn't surprise me if he just comes out to give an up some if you like. he is very well aware now of the enormous, not only the enormous nature, but how everyone is on tenterhooks waiting, because the deadline is coming very much closer. >> richard, i don't think he would come out just to say i have nothing. >> i don't know. i'm not so sure. i think he might be saying that is the situation on ocean shield. this is the situation here. this is what we've got for you. because he knows -- last night he set the parameters for the next few days. or for the next few hours. now it's time to tell us how those parameters are moving forward.

i just don't -- it's hard to get. >> i'm going with he's got some information. just a gut feeling. >> we all hope and pray. >> i wanted to touch on a real serious consideration that richard said with reference to the chinese holding back on the technology they have with reference to paul's expertise. is it possible -- why would the hms echo be going over there. just a question of mine, if the chinese ship had more technology than they're snowing just a question. it could be that they want to verify the same information. >> exactly. >> but then again, maybe that technology isn't available on that ship. just a pocket. >> colleen keller, you know, angus houston, the australians under tremendous pressure. i don't think anyone under more pressure than the chinese, though, because they have the most to lose, the most to gain. most of the passengers were chinese. but granted that he being the sort of person that he is, since he has been put in charge of this investigation, he doesn't appear to be the kind of person that will come out and say i have nothing new to tell you.

he will just tell you in a press briefing, i don't have anything new. and when i do, i will come out and tell you. >>. no i think he has something to tell us. but he could either tell us that they have detected a signal and that it sounds promising, or that they have detected a signal and they have discounted it. but at least he is giving us an update. everybody knows they have detected a signal and everybody is wondering what they're doing about it. i don't see anything unusual about this press conference at all. but i'm also not expecting any good news in particular. about the chinese ship operating down there, it is interesting to note that when the chinese ship did get the detection, it was relayed to the australians via chinese news agency and the chinese authorities, not directly to the australians, which indicates that the chinese ship was not operating directly under the australian search authority. and what is more, the reason why they maybe sent the echo is a, maybe they have more sophisticated equipment on board, but also because the echo is operating under the

australian search authority. so they have more control in that sense. >> all right, guys. stick around. you know, it has been a month of watching and waiting in agony for passengers' families. up next, we're heading to beijing where some families have returned home.

31 days and still not a piece of missing malaysian flights 370 has been found. not a wing, not a piece of luggage, nothing. it's certainly not either of the plane's critical black boxes. many of the passenger's families are returning home to beijing now, frustrated in the investigation. we want to go to beijing. david, how are families holding up? >> well, they're struggling,

don. the families you described in kuala lumpur, they went there to get more information. so clearly, they haven't got the information that they want, joining the hundreds of others here who are waiting to get some kind of clarity, just like the rest of us. but for them, of course, their bread winner is on board, their children, their grandparents. there is a whole host of cross section of chinese society in particular. more than 150 chinese nationals on board. and we should never lose sight of the fact that this is a human story primarily. and the people we have spoken to have very mixed feelings about this latest news. >> maybe this is the time. maybe for the next couple of days, next couple of months, next couple of years we will find the ending. but there will be a time that it will end. so to me, i don't want that it

is -- but if it's the facts, i have to face it. >> i feel the news from the press conference could be true because the area is where the plane should be. it's so strange that there was no emergency beacon signal. i think the plane glided on to the water and sank so the beak consweren't activated. >> so the family members following the news just like the rest of us, and some of them stealing themselves for a potential very long wait, don. and certainly, as that wait, many of them i have spoken to are just exhausted now because this process has just kept their lives on hold. >> so any encouragement also from the new bits of information about, you know, a possible ping here, a possible ping there, some debris here. does that offer them any sort of encouragement?

>> well, i think they're kind of jaded at this point. they don't want to believe or rarely believe anything they're hearing. time and time again, we've heard the following. that in fact they won't believe anything until they see physical evidence. as you said, when you introed the segment, they there hasn't been that physical piece of evidence at play, any kind of thing you can tangibly hold on to. so the data that has been used to analyze where this plane pointly went down, this audio or the ping recordings that appear to have been at least suspected to have been recorded by the chinese and possibly other nations, all of this is analysis that doesn't really give much comfort to these families. because for them to kind of start the process that. >> need concrete things. also, an important cultural aspect to this. in chinese society, you want to physically receive the body or the remains if it comes to that.

so even if we find some kind of physical evidence for many of these people, just they will never have closure in this case. so very traumatic indeed. >> well, it's pretty awful. thank you, david mckenzie. david mckenzie in beijing. as we mentioned, we're awaiting a news conference from the joint agency that is searching for mission malaysia airlines flight 370. it is being described as an update on the status of the search. as we await that conference, my panel is back, and we have some questions from our viewers. so, les, mary -- i'm sorry, a viewer is asking can't the black boxes be removed and thrown out of the aircraft? it's highly unlikely, but is it possible? >> no. they're permanently installed in the tail of the airplane. and the block boxes themselves are highly inaccessible. >> another question that we were talking about earlier before we

went on the air is can the black boxes be turned off? >> les? >> no. the only -- well, let me recant that. yes, they can throw a circuit breaker. they can be turned off. but it takes -- you have to climb into the electronic and engineering compartment. and it's a real process to get down there to do it. >> i just want to jump in on this question. i want to advance that question. excellent question about can the black boxes be removed. can they be or should they be deployable in the event of an accident, as in some cases they are in the military. in other words, in the plane in extreme, the black box leaves the aircraft. >> first of all, i want to add to what les said that yes, even if you can turn off the black box, the recording up to that point will remain in memory. >> so you'll know at this point someone -- >> what happened. >> so before that, which was the result of something that

happened, perhaps in the cockpit conversation or some other activity that resulted in somebody being able to do that. >> right. and that's our procedure if there is no maintenance around at this particular landing site, and we have an incident. we have part of our checklist has us go down into that compartment and actually pull the circuit breaker. >> is that mary -- it sounds like somebody is trying to get. in i'm not sure if it's mary or colleen. >> it's mary. you know what happened in silkair. now silkair is the strange one where the ntsb said it was pilot suicide and the united states district court, the jury said it was a rudder hardover. in that case our ntsb said that the pilot pulled the circuit breaker for the cockpit voice recorder and he was able to do that in the cockpit. so, you know, maybe a difference on the flight data recorder. but in silkair, and that was in

a public report, our own ntsb said the pilot managed to pull the circuit breaker on the cvr. so the cvr was all clean. and we didn't have anything in the crash sequence. there was nothing because the cvr had stopped. >> but up until that point, you heard what happened, right, until the pilot pulled. >> exactly. >> it was a different aircraft, mary, correct? >> right. 37. it was a 37. >> you can actually shut it off. is mikey k. there? how are you doing, michael. i have a question from a viewer. mikey kay is a cnn aviation analyst with us. here is what dan wants to know. can a magnetometer be used to help find the fuselage of a missing plane? >> magnetometer, if that is a mag boom type of situation which

is a magnetic anomaly detector, then that's exactly what the p-3 orion uses to detect submarines just under the surface of the ocean. i think these types of equipments and technologies are optimized for submarines. they're not optimized to find aircraft or debris that have crashed into the ocean. it all depends really on what the material is that you're looking for. if you're looking for a ferrous piece of metal, you might be able to pick something up. but if it's not large, it's not going to be affecting the earth's magnetic field, and that's what these mag booms do, they detect a difference in the magnetic force field of the earth that allows them to detect submarines. >> the answer is yes, somewhat you can use a magnetometer. but he says that's what a p-3 is using. >> but mikey says it's only for detecting submarines and not to the depth that this airport might be is my understanding, mike, you can correct me. >> that's exactly right, les, yeah.

>> colleen, go ahead. >> yeah, i totally agree. let's remember, this isn't a submarine. it's an aircraft. it's made of aluminum and carbon fiber. so it's a submarine on the other hand is a steel hull meant to withstand pressure. the depth that we're talking about several miles is way beyond what a magnetometer would typically detect a submarine at. >> okay, great. stand by. everyone, again, we're awaiting a press conference. just about 35 minutes. just about 35 minutes here on cnn. it is by the man who is in charge of this multinational search for the plane, the missing flight 370, angus houston, to hold a press conference. i'm not sure exactly what he is going to say, but we're going the carry it for you here live. it could be some encouraging and promising news. hopefully it is. what if the plane's entire instrument panel failed? would the jet be able to land

safely? that's one of the questions from our viewers. i'm going to take you inside our flight simulator to answer that question next. co: i've always found you don't know you need a hotel room until you're sure you do. bartender: thanks, captain obvious. co: which is what makes using the hotels.com mobile app so useful. i can book a nearby hotel room from wherever i am. or, i could not book a hotel room and put my cellphone back into my pocket as if nothing happened. hotels.com. i don't need it right now.

that this cockpit is laid out with wiring so that many of the instruments are different circuit try. >> that's right. so they're very smart over a point. they'll say if one of the captain's place were to go up, we have the first officer's, and they're not going to be connected so you have that redundancy. >> we have three flight management systems here. one, two, and three. so there is that kind of backup redundancy. also, let's say you lose this screen, there is a way to switch? >> there, absolutely. let's say one of these screens stopped working, we can move the instruments from one screen to the other so that you don't have a loss of information. you do it with all the screens here. same from martin's side. you can move all the screens. >> and last i want to point out, what is this little box? >> that little box is the standby instrument. so encompassing, included in that little box is all of these instruments just on a smaller scale. >> i just notice we're making

our big turn around indonesia right now. >> at the same time, let's say we lost everything. you lost it all. you would still actually a compass. >> you would have your magnetic compass, which cannot fail. >> and then you have your own pair of eyes or even at nighttime? >> you have your visual acute. >> so in essence, there is always still a way, even if it meant pulling out the charts and doing it the way they used to and plotting a course that way. and there is still a way the pilot could get it on the ground. >> the 777 pilot on the set is weighing in here, saying not going to happen. nope, nope, nope. there is no way you would lose the instrument. >> right. >> even a huge fire, nothing, never going to happen, les? >> that's -- i'm going to make it -- >> lightning struck the cockpit, never going to happen? >> martin said it the best way. that there is so many circuits and backup systems for this incredible airplane that it's not going to happen. it's just not going to happen.

>> it's not like you see in the movie where the little trail of fire and smoke and then all of the sudden this t whole thing. >> you can get down to a very uncomfortable situation where it's very -- it's difficult. and this airplane can actually get down to the point where there is only a very limited amount of flight controls that are effective. but it is still a flyable airplane. even without the engines running. >> even without the engines running? >> engines. without them running, yes, correct. because there is a -- we have spoken this about this before. but there is a ram air turbine that actually drops down with the failure of both engines that runs some of the electrical and a limited amount of hydraulic system. >> i just want to make it clear on all of this, the 777 has now been around for two decades plus. there has only been two accidents, three i think in total accidents involving the 777. serious two fatalities. with fatalities three in all there is 1100 of them out there.

this plane, it doesn't just have an exemplary record, it has an almost perfect record on safety. there is virtually no other aircraft -- >> but nothing is fail proof, richard. there is always chance. >> nothing is fail proof. but i'm putting it in to perspective. the nature of this aircraft there is no plane the pilots love to fly more from what i hear than the 777. >> marty mitchell, thank you, guys. always fascinating to see you. hopefully you guys are sticking around with us for this press conference. we'll be here until at least 1:30 in the morning. don't see any nodding heads. thank you, guys. appreciate it. coming up here, details on today's search plans for a flight 370. and we're awaiting press conference. 30 minutes to the top of the hour here on cnn. because my dentures fit well. before those little pieces would get in between my dentures and my gum and it was uncomfortable.

hmm. it's so huge, it's being broadcast on mars. heroes...bad guys... asteroids. available only on mars. there's watching. then there's watchathoning. ♪ welcome back, everyone. within the hour, a update from australia with the joint task force. also, new leads surfaced today in the search for flight 370. a senior malaysian government source says the aircraft may have deliberately skirted indonesian airspace in an effort to avoid indonesian radar. meantime, good weather is expected in the search area. nine military planes are help manage the search, along with three civil aircraft and 14 ships. the race is on to find the pings

coming from the black boxes before the batteries fail. three reports of possible audio contact have been reported. still no confirmation that they are connected to flight 370. i want to bring back my panel. mikey kay, richard quest, les abin, paul ginsburg, mary schiavo and colleen keller. so here is our first question we were going to ask. first question is from about the pingers. judy says each ping seems closer to australia, right. do you think something would wash up on shore from mh 370. thoughts? richard, you're at a loss for words. >> i mean we have so many excellent experts from everything from pilots, weather, radar. >> all right. investigator colleen keller, yes, what do you think? >> oh, i guess it. great. i think that that depends on the currents, don. so if the currents are moving in the direction of land, then

eventually you would see things washing up. and i think the currents are generally moving in that area. but it's still going to take some time. so if you have a lot of time, you might start doing some beach combing. >> but we're talking about that. think about it. when you said close to australia, how many -- what is it, like 1200 miles, 1300 miles or so off the coast of australia? >> about 1100, 1200 miles at the moment. >> so that would take a while to wash up. here is something from tamara says okay, so if we found more than one potential ping, how long will it take, roll the prompter up, please. how long will it take to get a side sonar in the water? do we know? >> i defer to paul. >> mary schiavo? please answer that question. >> well, i don't know how long it's going to take to get in the water because presumably, it's on the echo. but i do know how long it's going take to get down because it takes an hour for every --

how many -- it's going to take 11 hours just to get the thing down to where it can scan the ocean floor. so once it gets there and they get it in the water, it's going take a day to get it down at the floor. >> and it's all depends on which of the assets. which of the assets has got it. so we know echo is now on-site. >> right. >> and can deploy that which it's got. but if they have to wait for ocean shield, ocean shield is still doing its own business 300 miles away. so if they declare that this is, you know, a valid thing and they want to get something down into the water, it will all depend on whether or not echo has it on board. >> right. and again, i want to tell our viewers rewith waiting for a news briefing at the top of the hour, just about 20 minutes or so. we're expecting angus houston, the man who is heading the search for the missing flight 370 said a short time ago, about 10:00 eastern time that he is going to hold a press briefing at 12:00 eastern time here in

the united states. to update us on the search. we understood, we heard from him last evening at midnight. it was midnight that he came on, right? we heard from him last evening saying that the echo had heard something, that the ocean shield possibly had heard something. there were three different events, one by a chinese ship and one by the australian ship. and that they were possibly going to move the australian ship in the vicinity where the chinese ship had heard the ping earlier. so the information we have now is that. and you said they also had -- some of the satellite coordinates in order to update the search area, to hone in on the specific search area. so now we're hearing, we're going to hear from him again, not exactly sure what he is going to say. but believe it or not, the plane crashes equal future safety and security in improvements. and when that happens, i guess it does. because everyone looks at what they can improve.

next we're going to show you how not finding 370 could impact future flights. (dad) well, we've been thinking about it and we're just not sure. (agent) i understand. (dad) we've never sold a house before. (agent) i'll walk you guys through every step. (dad) so if we sell, do you think we can swing it? (agent) i have the numbers right here and based on the comps that i've found, the timing is perfect. ...there's a lot of buyers for a house like yours. (dad) that's good to know.

(mom) i'm so excited.

there is no concrete evidence of where it is or what has happened in its final moments. now some people are wondering if the plane will ever be found. how that scenario could impact not just this case, but the future of aviation. >> reporter: as searchers race to find any wreckage of flight 370, the cost of not finding the plane could impact the safety of future flights. accidents equal safety and security improvements. in 1983, a fire broke out in a lavatory on air canada flight 797. the plane landed, but 23 people on board died. after that, smoke detectors and automatic fire extinguishers were mandated in aircraft lavatories. in 1996, hazardous cargo on valujet flight 592 caught fire. >> what kind of problem are you having? >> smoke in the cockpit, smoke in the cabin. >> the plane crashed in the florida everglades. 110 people died. it led to new cargo hold safety

rules. but not finding flight 370 or its data recorders could be a missed opportunity for change. >> whatever brought down that flight, whether it was fire, hijacked, pilot suicide, explosive decompression, a. bo, whatever, it's important to find that out so that we can fix it so it doesn't happen again. >> reporter: and it's security too. the september 11th hijacks led to strengthened cockpit doors. the shoe bomber led to shoe checks. >> unfortunately, we've had a history of sort of graveyard policy making. you wait until enough people die and then you make a change. >> reporter: with so few crashes in recent years, the faa is more proactive in finding problems that could cause crashes before they happen. now with malaysia airlines flight 370, there could be lessons to be learned, but only if they find out what went wrong. one example of why finding hard evidence:00 what went wrong is

so important, in the words of a former ntsb investigator, if there was a problem with the plane, it could be fleet wide. and if that's the case and no one knows about it, he said guess what? they'll know about it the next time it happens. and that's not good at all. of course, the same is true of unidentified security issues. cnn, washington. >> renee, thank you very much. my panel is back now. les, you fly 777 how important do you think it is to find this missing passenger jet to determine exactly what went wrong and how to improve. how important is that? >> it's extremely important. the public has lost confidence. they don't know what to lose confidence in, actually. is it the airplane? we've been talking about how well designed it is. but, you know, the public is saying, hey, we're going to get on an airplane. we could be lost in the middle of nowhere. so it's very important to find this. >> so we talked about the shoe bomber.

we have to remove our shoes at the airports now. we're talking about reinforced cockpit doors after 9/11. what is the next change, richard? >> the next change is not some blanket you can't do this, you can't do that. it's smart security. it's know your passenger. very much what they're doing here in the united states with the tsa, precheck. know who is -- know who the passenger is and who you need to be concerned about. and that's not profiling per se, but it is ensuring that you don't worry about certain people so that you can focus your attention on other people. it's very difficult to do. but it's the allow theory. it means you don't waste time searching 75-year-old grandmothers. >> mary, what about also that the information that is important to figure out what happened and how to improve the next one from happening doesn't end up in a debris field? >> well, that's very important. in fact, you know, the

importance of accidents to regulation in the united states, we used to call -- sort of still do. but we call the faa, the federal aviation administration, the tombstone agency. and we call them that because we said we regulated it by counting tomb stones. and that's not just being flippant because in fact they have to do a cost benefit analysis before they put forth any regulation. and the cost of the regulation must not exceed the value of the lives lost. because if the value of the lives exceed the cost of the regulation, then they'll go ahead with it. but if the regulation is too expensive, then they won't. so if -- the secret of what caused the crash is lost with the plane, they'll never be able to do that valuation. and they'll say well, we have no indication of how much this loss of life would cost versus the regulation. and that's really how we regulate. we actually have to evaluate the loss of life versus the cost of

the regulation. and that's actually a federal reg. >> how long do you think before we start seeing some information that is where you can just pull it out of the computer instead of going to the bottom of the ocean with multimillion-dollar searches to find? >> as soon as possible. absolutely. that has to be the next technical focus that is to get that information off that airliner and up into the sky and where it needs to be in a safe place. and i'd also like to expand on what richard said as far as added security. and i would say that has to include also the crew and anybody that has access to the plane in addition to the passengers. >> yeah. >> of course. >> colleen? >> close the loophole. >> yeah, i mean, it's obviously going to come down to bandwidths and how much it costs to get this information over the satellites. i understand that the airlines

are resistant to paying that due to the cost benefit analysis that mary was talking about. i'm not surprised. >> what is that noise? do we have any idea? what is that that we're hearing? any idea? >> one of the things the pilots have always said, whenever security is raised about pilots and they're being searched and all these things, the pilots have always said, well, hang on, what is the point? we're to be get behind the wheel of this thing. if we want to do anything, we can do it ourselves without any problems. so if the pilots are involved in any shape or form in any incident, because they're the once driving the bus, inevitably, it's more difficult to deal with a security question that relates to those that are members of the flight crew. >> michael kay? >> you don't have to have a

board of inquiry conclusion to start the lessons learned or lessons identified register there will be a register that is already up and running where people will be learning from this whole experience. you don't have to found the jet to understand why and what to get to that place. and there are a myriad. i mean, richard has been talking about security. but there is the technological aspects. we're talking about cameras in cockpits. there is the reality of that versus will he actually achieve something. you've got the procedural aspects. let's not forget about area radar here and the emergency protocols that should have happened once vietnamese airspace didn't see malaysia 370 coming into their airspace. who did they talk to? what are the protocols there? there is the security aspects there is the training of the pilots. so there are a myriad of areas where people will be investigating already to see how things can be tightened. >> yeah. and richard brought up cameras in the cockpit, which is les abin really loves that subject.

>> cameras in the cockpit, my old issue is put them in there. it's not going to help our safety. it's an after the fact. it's an after the fact type situation. >> and i don't think cameras in the cockpit are going to help your investigations. the camera in the cockpit can't see what the feet are doing on the rudders. you have to go to the fdr. if somebody leans forward to touch a switch, we can see this when we see pictures from the 777. >> the question is where do you position the cameras to make it -- >> i think you put them up there and you don't tell them where they are. >> they used to be over the shoulder cameras. >> so you don't trust the men and women? >> you put it up there so if someone tries to disable it, you don't know where to go to disable it. i think you put it in the cockpit and you don't tell them. i know we have cameras, the tv cameras trained on us. but you can look around the room and see six or seven or eight different cameras where people are on camera every single day in their place of business on

the train, on the street, regardless of where you go. and i don't think pilots should be any different. >> have you got a camera in your office other than a skype camera or whatever for making a call? >> i don't know. i don't know if there is camera in the office. i have never asked cnn, my boss or security if there is a camera in my office. because when i'm at work, i don't do things that i don't want seen by everybody else. >> but do all the cameras enhance your security and safety here? >> i would imagine they do, yes. and i don't see why it would be any different for a pilot. if you in your private life, fine. but when you're in the cockpit, you're on camera. >> but we have to be able to disable the system in case it's the cause of an issue, an electrical problem, a source of smoke or fire. we have to be able to disable any system. >> no one is saying you can't. just thought i would mention it. >> live pictures of the conference room where they're

going to hold the live press conference. just at the top of the hour on cnn. the man in charge of this multinational search angus houston holding a press conference 12 eastern time in the united states. it's going to be of course, 12 noon in perth, australia. and we'll get everyone away what we've been talking about after this break. it has been a month since flight 370 disappeared. the world has watched and waited along with the families of those on board that plane. next we're going to take you back to kuala lumpur where the whole investigation began. what you wear to bed is your business. so, if you're sleeping in your contact lenses, ask about the air optix® contacts so breathable they're approved for up to 30 nights of continuous wear. ask your doctor about safety information as serious eye problems may occur. visit airoptix.com for a free one-month trial. suddenly you're a mouthbreather. well, put on a breathe right strip er

an all-out search is back under way right few or to the black boxes from the missing malaysian airliner. it is imperative that the recorders are found to try to determine what happened to flight 370. especially now that malaysian authorities believe the plane may have intentionally taken a route to avoid radar detention. cnn's jim clancy live in kuala lumpur for us. jim you have been there since day one of this investigation. what do you make of the source coming out now with the information that the plane may have deliberately skirted indonesian airspace? >> it only confirms what was already known. it reinforces it. it's a clear fact one of the things that because it's on radar, you know that that is what happened. so it reinforces it that way. but 30 days on, you know, in the

words of one of the family members very close to a member of the crew of flight 370, their attitude today is we have given up hope. they are not satisfied at all with the way malaysian airlines has handled them. they haven't been brought into the briefs like the other families have. people are frustrated after a month. this goes down as one of the biggest mysteries in modern aviation, don. there is no doubt about that. and it's going to be an incident that spurs change in the industry. we're going to see tracking of planes. i know you were just talking about some of this. it's also going to see governments required to use the available databases to screen out passengers for their lost or stolen passports. don? >> you know, you've been there, again, from since the very beginning. how are people there reacting a month later? still very little answers, jim. but also, you know, a few

possibilities here and there. i'm not sure if it's enough to encourage them. >> well, we have no shortage of possibilities. we have no shortage of theories and conspiracies. what we don't have are the hard facts that it's going to take to unravel. what did really happen inside the cockpit? was there one incident? were there multiple incidents? what happened to this plane? why did it veer so far off course? why did it skirt the territories where it might have caused an alarm. why did it go on a pointless route towards antarctica in a very deep part of the southern indian ocean. these are unanswered questions. and the search right now and the upcoming press conference are very important to unraveling that mystery. don? >> yeah, it certainly is. jim clancy circumstances thank you, jim, has been, again, in kuala lumpur since the very beginning, covering this story and watching the families from the beginning. just a roller coaster of emotions for them. one day they think they have

some answers. the next they don't have any answers. one day they're being told that everything is lost and the plane is in the ocean. but still, no evidence, no sign of their loved ones. and they really want to come -- they really want to get some answers here. and we can understand why. >> hello, everyone. i'm don lemon. i want to welcome our viewers in the united states and around the world. in just minutes, the head of the joint task force hefding up the search for malaysia airlines 370 is about to speak. all me we know is it is a, quote, update and read into that what you will. an update. but we will bring you that live, just as soon as he steps out, as soon as angus houston walks out, we will bring that to you live. and here is what we do know, though. for the first time, we have what could be sound from the plane's black box. search crews are scouring the indian ocean, trying to find out if there is anything to those
