>> a ticking time bomb of public employee pensions. >> i think anybody can be beat. this is a cnn special report. i'm don lemon. we begin with breaking news. just released tonight, analysis from the fourth mission of the bluefin-21 is in but yielded nothing. so how could that be good news? >> the visuals that we managed to get from the bluefin 21 were very clear. not in finding what we were looking for, but what the seabed looks like, and that gives us a bit of relief as to the next few

days, we're going to intensify the deepwater search. >> so all of these leads and nothing more than dead ends and now via his twitter account the acting transport minister says they're looking at the possibility of deploying for auvs. what could this be costing? s cost of the search for flight 370 to be in the ballpark of $234 million and that's with zero results so far. is it time for a new search strategy? you have been tweeting us your questions by the thousands and we have got top aviation and security experts standing by to answer them like this one. if they are searching in the wrong spot, then why did they hear pinging? everyone said it could only be the black boxes. nic robertson in kuala lumpur andrichard quest.

good to have you back. i want to start with you, michael holmes first. despite a lack of concrete evidence, searchers seem to be getting more and more positive they are looking in the right area. why is that? >> yeah, because that's where those pings were, and they've really focused down the search area, don, and we are hearing from people involved in this search at high levels that they are confident. they feel they're on top of it. they are in the right area and they are hoping for good news. as you said, four dives now completed. we have had the data back from all four of those dives by bluefin-21. not showing anything concrete in terms of what they're ultimately looking for, that is the black boxes or any sign of wreckage, but they are happy with the resolution and the way that bluefin-21 is working. they are underway now on the fifth dive. so far, they have covered in the

region of 110 or 45 square kilometers, 145 miles in the trip so far. significantly they have gone below the 4500-meter mark. the bluefin doing its job. let's keep this in context. this is still very early in the search by the bluefin-21. they want to give it a little bit of time and cover that area and they're working their way through it now. like i said, we are just hearing word those in charge of the search are confident. they feel they are in the right place, don. >> all right. michael holmes in perth. michael, thank you very much. nic, despite the positive assessment the reality is the search is yet to turn up anything. i want you to listen to what the malaysian transport minister said today about the search if they continue to come up with nothing. >> there will come a time that we need to regroup and reconsider, but in any event, the search will always continue. it's just a matter of approach. >> nic, does this mean the malaysians are losing confidence? >> it appears not.

i mean what he's gone on to say he recognizes the search can take a long time and said all along malaysia is committed to this and they will find a way to do whatever it takes to keep searching and he's also said in terms of money that's the least of his concerns. whatever adjustments he's making, it doesn't appear to be -- it's not going to be sort of to scale this back in any way. indeed, the government here has formed three committees to work with the situation. one of the heads of that committee, the transport minister or acting transport minister tweeted this morning is even suggesting that they bring more of these submersible bluefin-21-type underwater vehicles to aid and perhaps speed up the effort here at the moment. but the acting transport minister has said, look, when it comes to money, we've got countries lining up that may not have the assets that can help us but are willing to put money to help make this continue an ongoing mission. don?

>> i want you to talk about this more, about more auvs because the transport minister has been active on twitter and he's been tweeting about the possibility of deploying more auvs and a visit by malaysian officials to families in beijing. any further details on that? >> yeah, at a press conference earlier on thursday, he said that there would be upcoming in the next few days another high-level delegation going to beijing to talk to the families. of course, on wednesday there was a disastrous press -- or not press conference, a video conference between technical experts in malaysia and families in beijing. the families in beijing discussed it because it didn't work. they feel that this -- after an hour, they walked out of this video conference. the malaysians couldn't get a good connection. and therefore the chinese families weren't getting their

questions answered. it does seem they are sending the high-level delegation. what we have had in the last hour or so coming from the twitter account of the transport minister is underlining the three committees and he put out a note on each of them that the committee that's working with the families will send a high-level delegation to beijing over the weekend, perhaps meeting with families as early as monday. the committee that's responsible for the search and equipment involved in the search, they are going to, as you are suggesting there, put more auvs down in the water. that's that suggestion and the other committee, he said that committee is now looking at getting a panel up and running to investigate everything surrounding -- everything surrounding the search and what happened in the hours before and the days before that. so it does seem that he is trying to energize this earlier commitment. why he feels under pressure to do that, not clear. certainly getting answers to the families in china is a very

pressing issue and the government here is still failing to do it adequately, don. >> nic robertson in kuala lumpur. thank you very much, nic. back to perth with geoffrey thomas, and robert the editor of "flying magazine." richard quest is back with me of course back with me here in new york. geoffrey, to you first, you see some parallels between what is happening right now with mh-370 and the successful search for air france 447. explain that to us. >> yes, indeed, don. i mean with the search for 447, when they finally triangulated where they believed the wreckage was, they put down a bluefin-21 to have a look. it took them actually eight days, even though they knew virtually precisely where the airplane was, it still took them eight days to find it. the wreckage on the bottom was confined to a very small area,

as well, so we're only into day 4, 4 1/2 into this search on the bottom. we have a long ways to go yet before we sort of really completed a thorough search of the area where the pings have come from. don't forget, we have had four very strong pings. we had two fade out pings. according to one of the greatest wreck hunters of the world, david burns, he says we've found it. he's very, very confident that they are looking in the right spot, and there's also a very high level of confidence, off record, from officials who say, yes, we are looking in the right spot. >> richard quest with me here in new york. "the wall street journal" is reporting the plane may have been on autopilot headed to perth. cnn checked with sources in the australian government who said their official did not tell the journal that. how does this reconcile with other reports that may have taken deliberate action at this point? >> it adds some interesting

notes to this whole question, where was the plane headed and why was it going in that direction? "the journal's" report says the plane was on autopilot and going toward perth. the reason why that might have been could be any one. it shouldn't have been, is the short answer, because it could have never gotten to perth. it was always going to run out of fuel before it got to perth with the amount of fuel it had on in beijing. if that's right, it goes straight into the nefarious bin because it means somebody programmed the autopilot -- >> either pilot or co-pilot, whoever. >> right. but with them denying it they have not confirmed that. we have to put it in the suspect let's not go too far with it. >> let me give get to robert now. given the clues at hand, which we acknowledge it's limited right now, what do you believe happened to this aircraft? >> well, i think that some of

the comments that richard just made are interesting. the whole idea that someone is saying they belief the aircraft was on autopilot and headed for perth, it is patently absurd. they don't know what the autopilot was doing. if they find the black box and there's data we may know what the autopilot was doing, what was programmed into the fms and no one has any way of knowing that. i think what was happening, i think all of the evidence is starting to mount. the cell phone call that apparently hit a tower from the co-pilot's cell phone is just another little piece of evidence that by itself doesn't really mean anything. when you add them all together the it seems as though took the airplane and intentionally flew it away from radar, disabled communications and attempted to fly it far away so that no one would ever be able to find it or be able to track where it went. it seems as though it was some kind of very strange suicide mission.

the intent of which was never to be discovered. >> which is interesting, now that we are here and i'm hearing what you are saying and everybody else was saying. it is almost we are back at day one. >> we are, don. not quite at day one but not far off. all we have to work on is inmarsat pings, which we knew about from middle of march. >> the handshake. >> yes. >> and mathematical probability. >> march 25th is when we knew about that and we have the pings that they have just found in the last couple of weeks, and that's it. >> yeah. all right. thank you. stick around, everyone. i want to bring our audience up to date on the tragic sinking of a ferry in south korea right now. a press conference just wrapped up in seoul. officials said the captain of the ferry was not at the helm of that vessel at the time of the accident. it was the third officer who was at the helm. also cnn's affiliate in seoul reports that eight divers have entered the cafeteria of the

submerged ferry in search for survivors. 25 people are now confirmed dead. 271 remain missing. we're going to keep you up to date on this very important story as we get more information here on cnn. when we come right back, how much would you guess the search for flight 370 is costing? i will have that mind-boggling number for you. and later, a report from inside a sub. david mattingly with a unique look at the challenges of an underwater search. hy i got a new windows 2 in 1. it has exactly what i need for half of what i thought i'd pay. and i don't need to be online for it to work. it runs office, so i can do schedules and budgets and even menu changes. but it's fun, too -- with touch, and tons of great apps for stuff like music, 'cause a good playlist is good for business. i need the boss's signature for this. i'm the boss. ♪ honestly ♪ i wanna see you be brave

i'm don lemon. breaking news tonight. analysis is in for the fourth bluefin-21 mission. it has yielded nothing. the fifth bluefin mission underway right now.

i want to bring in my experts. jeff wise, the author of "extreme fear: the science of your mind and danger." bill waldock is a professor of safety science at embry riddle aeronautical university. aviation attorney jim marks, jim tilmon, retired pilot, richard quest is back with me again. thank you, gentlemen. geoffrey, to you again. another promising lead and another dead end. was this oil slick found on top of the social a dead end? the analysis it wasn't connected to flight 370. did that surprise you? >> i guess it disappointed me a little bit. i guess it's not a surprise when we consider all of the rubbish that's in the ocean, the oil that's cast aside off of fishing boats, off larger ships. one of the things we have discovered, unfortunately, in this search is how much rubbish there is in the indian ocean and other oceans, as well, obviously. so there's a lot of hope

attached to this that this would be an absolute definitive link to this airplane, but the confidence still remains very high that we are looking in the right place for mh-370, despite the setback with the oil. >> okay, so, bill, the malaysian transportation minister said the search going forward may need to, quote, regroup and reconsider. what would that new search look like? >> well, it might be something along the lines of what actually happened with air france. there were three previous searches before the fourth search using the underwater, automated underwater vehicles actually found it. and they essentially had to do the same thing. they stepped back and reconsidered, let's think about this in a different way and in their case, they went back to the last known position of the aircraft, put three separate autonomous underwater vehicles down and

literally found debris within 6 1/2 nautical miles of the last known position. sometimes it does take time to search these areas. the period of time where they actually found the debris, it was actually the 18th mission of the auv that found it. we are in the fourth and fifth mission. we are early in the search process. >> richard quest, i asked him and i said, what could a new search, a new mission look like. maybe it should be what should this one look like because you have been looking at what the malaysians should be and are doing. are they doing everything correctly? >> they're doing everything up to a point, absolutely. but the thing -- normally by now, these are the two documents that regulate how you are doing. this is the annex 13 that we hear about. aircraft accident and incident investigation. it's the bible for who does what, where, when and why. this is the manual of aircraft accidents. this tells you what the report should look like, how they

should be written and what should be included. in most situations, within 30 days, you should have had a preliminary -- >> it says that in that. >> there should have been a preliminary report with a basic statement of facts and circumstantial evidence. i think we can allow the malaysians a certain amount of leeway bearing in mind they haven't even found the plane yet and they have been concerned with working out where the aircraft is rather than writing preliminary reports. but at some point they are going to have to write that that preliminary report that sets out the facts, the plane took off, this is what happened, this is what we know. that's what we need and need it probably sooner rather than later. >> because it has been more than 30 days, 40 days. what's your reaction to that? do they just not have enough definitive information to even begin a report? >> i'm sure they don't. i don't think the government is

in a position to release much, if any, information. the information has been so inconsistent and they have embarrassed themselves. i think if they put anything out that is official, it will only cause more embarrassment. i think they will be very careful before they publish anything official in writing. >> jeff, you have been calling for inmarsat to release data to the public. if it comes up with nothing will it be helpful to release the information. >> oh, absolutely. i really think there will be a lot of pressure on them to release it. it is all we have to go on. it is a extraordinary situation that the australian and malaysian authorities have been cheerleading these ping and other evidence, really saying, look, we are very confident it is here. really promising us we are going to find something. yet every day that goes by with the bluefin not finding something, the chances that we are going to find something dramatically decreases. because really i mean

i think it's not fair to compare this to air france 447. we are supposedly looking for pings. and these pings, the acoustic -- the towed locator only has a range of one to two miles tops. this should be a very compact area. it should have already have been searched. we should have already ruled out the pings were from the mh-370. >> i want to get to jim tilmon now. this is a huge question and maybe the most important question especially when it comes to dollars. the top adviser said the search could cost a quarter of a billion dollars. that's in u.s. money. who should foot the bill for this because how long this search goes on depending on how much it costs and who foots the bill is how long the search will go on. that's what will determine that? >> this situation is one that affects all aviation, particularly commercial aviation over this entire planet.

it's important that we understand that this is not just a malaysian situation. we have a lot of lessons we are learning out of this. it is expensive learning but we have to pay the price in order to get what we need to know for future events. this is not just a one-time thing and don't worry about it. it will never happen again. don't count on that. that's not a good idea. >> very well put. geoffrey thomas, let's say they find something, how will this be released? is there a protocol that needs to be followed? >> look, i think probably forget the protocol for a moment, i think good sense is probably a better word. if they find something positive, i believe that really has to be announced by the malaysian prime minister. first of all, they are going to have to tell the relatives in a better way than they did last time, not through text messages had on mobile phones. so it may well be what they do on the fifth mission or the sixth mission find something, it

may be a couple more days before we are told because they have to get it right this time. because this will be absolute proof positive they have found the resting place of mh-370 and there's a lot of ramifications to that. so my sense it will be the malaysian prime minister who makes that announcement. >> geoffrey thomas, thank you very much. as always and everyone else, please stay with me. when we come back, we will go below sea level to get a better look at the search for flight 370. our david mattingly reports from inside of a sub next. on an ancient burial ground.

we have breaking news tonight as the data from the

fourth bluefin-21 mission has come in, but unfortunately it has yielded no evidence of flight 370. the fifth bluefin mission underway now. it's 42 days in to the search for flight 370. the focus has shifted from above the surface to the ocean below. cnn's david mattingly is inside of a submarine off of the coast of horseshoe bay bridge, british colombia. david, talk us through the challenges of an underwater search. >> don, the challenge is, it's an incredibly long list, not the least of which being the tremendous depths you have to go to and the pressure you have to deal with going all the way to the bottom of the indian ocean. we are talking a couple of miles down. there's only a half dozen manned submersibles that can actually go down and do that kind of work. this vehicle we're in right now is not one of them. we're at the bottom of horseshoe bay in british columbia. i'm with phil nuytten.

he's an internationally known as a deepwater dive expert. you actually develop vehicles like this so people can go deep in the water, places they never have before. and something i have been learning from you as we have been down here is how difficult, even the simplest move seems to be. >> yes. it tends to be quite a chore. no question about it. the biggest attribute you need for this kind of work is patience. >> show us. we have a mock up of a black box. of what a black box would look like down here. it is already in the claw n the device on the outside of the vehicle here. it takes more than ten minutes under the best circumstances for that claw to grab the handle. now, watch what happens when we try to put it into the basket that we'd need to take it back up to the surface. go ahead. this isn't something you think would be difficult, but you have to move by inches here. this is just two feet in front of our noses right here. and you can see how tough it is

to get that box into the basket. i can feel the submersible moving while we are doing that. so you have to deal with currents. you have to deal with visibility. it would be pitch dark out there if it weren't for the bright lights on front of our submersible. but the point we are making here, you have to move so slowly because if you drop that box, if you make a quick move or watch what happens when we turn the propellers really fast, the thrusters on the front, it just blows up the sediment on the bottom. it is like blowing into a handful of flour. you would be momentarily blinded and then you have to stop and wait for everything to settle. here it comes in from the side. it's so pain staking down here. and these are some of the best circumstances we could have. we are only at 50 feet. imagine that difficulty multiplied by 200, two miles down. it would be such painstaking work at the bottom of the indian

ocean, that is, if they ever find the black box and if a human being ever has the opportunity to go down and try to retrieve it. don? >> all right. thank you very much, david mattingly for that. i want to bring in jules jaffe. he's a research oceanographer. richard quest is with me as well. jewel jewels, good to talk to you. we just saw david mattingly demonstrate for us what it is like in a sub. granted, this is approximately, the approximation of searching underwater. what did you think of that? in that -- >> i know that it is fascinating television nonetheless but really shows you the challenges. >> yeah, i mean, i don't think the way to do this is actually in a sub. as part of doing research for the show, i went around and asked colleagues. big ocean, small group of people working in this area and actually there was nobody that really believed working in a sub

is the right way to do this. imagine you are in a sub and you have two, three, four hours and you start working and then it doesn't go well. all of a sudden you have to go back to the you are surface. if you are using an rov, a remote operation vehicle. you have a guy 24/7 on the ship. somebody can relieve that person. we know how to do that kind of stuff. the idea of using a sub to be really honest and the consensus of my colleagues, it's not really a good idea. >> the thing is not to show using the sub. that's not the premise here. it is to show the conditions under the water how dark it is, the silt. how they will retrieve the black box potentially even if it was unmanned vessel or however they retrieve the box. not as if they would be using the sub to do it but showing the conditions there. >> you know, there's no doubt that working in the deep ocean

is a very difficult thing. >> thank you for clarifying that. and it gives the public an idea of what we do and how hard it is to do. i would have to agree. there are people specially trained to do those kinds of things and there are a number of successes they have achieved in that scenario. sure, it's tough. we need, you know, expert people that need to know how to work underwater with underwater vehicles and stuff like that. it's really tough but these guys can do it. >> let's talk about the bluefin now. that's what they are using now. that's the submersible they are using now to go under. it's had some problems and some successful missions, as well. i don't know if you can even call the first day a problem

because it did what it was supposed to document it went too deep and did what it was supposed to do and came back up. i don't know if that is a problem. it is called working right there. the prime minister tony abbott said they will exhaust everything there, exhaust everything they need to do as long as they need to take for the bluefin to cover this area. how long do you think that will take? >> you first have to know how big the area is. the side scan can see 1,000 feet to either side and if it is moving four, five miles an hour, you are going to be mapping something on the order of 25 to 35 square miles per day. one of the disappointing parts of the story, i would have to agree is we haven't found it yet. it is sort of surprising. it sort of means the pinger, fuselage or debris is not very close together. hopefully they are not far apart. i wouldn't say we're on the gauge, not in the red zone yet. we're still green, yellow and i think we need to be patient to be honest with you.

hearing the australians talk about that, it actually gives me some, you know, hope, because what i am hearing in techno world is the side scan images are looking good. we're not seeing a lot of clutter. if the stuff was there, we'd probably be able to see it. i think it is hard to know. i'm not a soothsayer but i think there's some confidence we will have to keep looking in a world where you can flip an iphone or anything, and an app and call and be patient and hold on. we have to be patient and hold on. this is not the deep ocean -- i mean that's not the deep ocean. i'm not in a panic state. i think we are heading toward yellow but still in the green on the gauge. >> you are not a soothsaying? why do we have you here. johnny carson used to do that. >> yeah, yeah. amazing kressley, cresskin. >> you got it right. >> is there a chance of a false

positive result in these images. >> you mean the side-scan images and sonar. >> yeah. >> that's what we worry about. this is the non intuitive part of it. we know that there is a layer of silt. but what is under that silt is probably not known. we're looking for, as i said a few days ago on your show, the sort of foreground and the background, and, yeah, if there's a boulder there that is sort of the same size as the black box and it's covered with silt, i don't think we will have an easy time telling the difference. so the answer is yes. >> thank you, oh, soothsayer, jules jaffe. we appreciate you and thank you very much. have a good holiday. tempers continue to rise. families are demanding answers in the face of more dead ends. next, what officials are doing in response. co: sometimes you don't know you need a hotel room

moments ago in beijing, a candlelight vigil for the anguished families of the passengers of flight 370. it has been 42 days, zero results. malaysian officials will travel to beijing to meet with the families of the passengers of flight 370. after facing the families they will head to perth and meet with angus houston.

c cnn's jean casarez has more now. >> you are all bloody liars and you are lying again to us now. >> reporter: the frustration bubbling over. the relatives of those on board malaysian flight mh-370 want information and they want it now. that may be why a malaysian delegation is traveling to beijing to meet with the families on the ongoing search. the families have a list of 26 questions that they want answered including what is in the flight logbook, maintenance records and the recording of air traffic control that very night. >> it's very personal, very personal, from each person's idea of what happened in the very beginning. >> reporter: maarten van sluys

knows what the families are going through. he lost his sister on air france 447 in 2009. van sluys flew to help survivors. he says they have become like family. >> embrace people. you don't even know where they live. what they do for a job or anything. and you start to hug these people, people who are crying, very loud and very bad shape. and suddenly you feel, oh, i know this man. >> reporter: with no evidence on the fate of the plane so far, some loved ones say the investigation is being mishandled. >> whether it was catastrophic failure or whether the plane was taken intentionally, we believe options should be explored and many of those options are actually over land. they are not over the sea. >> reporter: if and when the answers do come, if the families finally do learn what happened to their loved ones, the outrage may linger. >> yes, this is something that i understand is very bad for them and they are in my opinion very

emotionally destroyed. >> reporter: those who have been through it say, take that emotion and advocate for your family member so that flight 370 is never forgotten. >> thank you very much, jean casarez. i want to get my experts' reaction on the clash between flight 370 and malaysian officials. joining the panel is karlene petitt, an international pilot and author of "flight for safety." good to have you aboard. okay. thank you for joining us. but piers i want to go to bill. a committee of the families released a list of 26 questions that they want malaysian authorities to answer. the first 12 are on the elt emergency locator transmitter, including this one. they are a little long. bear with us. they are there on the screen for you. is it possible to break the elt at high impact? where is the 406 megahertz elt located?

the tail of the flight or on the ceiling of business class? and when a plane is trying to land on the sea, can elt be activated? are you surprised the families have so many questions about the elt specifically? >> that's a product of the fact that we have so many unknowns. the elt could be in a couple of different places on the airplane. one thing it is going to do as soon as the plane goes in the water and sinks it will stop transmitting because it can't transmit through the water itself. >> okay. richard, this is for you. the next seven of the family's questions are on the black box. and this is an interesting one. it says, what is the sample that boeing has sent to australia to compare with the detected pinger? was it from a normal black box pinger on the black box on

boeing 777 or even the exact black box mounted on mh-370. do we know that boeing sent a signal to compare with the pinger? >> no, we didn't know who sent what when, where or how. what they are trying to gauge from that is why do the authorities, why are they so confident? if you read back again, when they did find these or heard these pings, they said it was consistent with the black box or flight data recorder. so they want to know upon what basis can they be confident that it is a pinger from a triple seven black box. >> all right. the next one, a new panel, the final of the questions on protocol, we want mh-370's logbook. we need malaysia civil aviation control's voice recorder and we require the atc audio. i think, karlene, like all of us they want to know what happened in that cockpit. >> yeah, they do. and here's the thing with the logbook. it is irrelevant. because we now know the plane was intact.

it flew for seven hours. there wasn't a fire and it didn't fall out of the sky. it actually flew. so any maintenance on that is irrelevant because the airplane was working fine. and we do know there was human intervention. a pilot did -- whether the autopilot was on or not, it wasn't programmed to fly around australia. somebody did it. they were probably using the heading select if, in fact, it was on. so a person did this. the only thing about the atc, if they have it and somebody did get in to the cockpit and could be something horrific on that communication, there could be a reason why they don't want to let it out and let us hear it. robert you are not in agreement. let's hear it. >> you're nodding in agreement. what's up? >> i think karlene is right on the money. as far as the tape is concerned i don't think there is any chance there is a smoking gun on the atc tapes or we would have heard about that. that would be guiding the investigation right now. and as far as the -- she's right on the money as far as what

happened with the plane. somebody flew the plane, whether it was hitting heading select or programming it through the fms. but we know now, as far as the logbooks are concerned that would make it irrelevant. we don't think the plane broke. we think it flew for a long way. not as a result of mechanical malfunction but human intervention. >> i see you -- you seem so uncomfortable in your seat. >> well, just the comment, we know now because we don't know now. we have a variety of statements from the authorities that basically say it was deliberate, but we don't know why or how. so i venture to respectfully disagree. to say we know now, we don't, sir. >> yeah, we do know. >> do you care to respond to that? >> we know so much about it. we know where the plane flew. we know that it went through a

series of way points that would have been -- >> no, we do not. no, we do not. that way point has never been confirmed. we merely know a route that it took that corresponded to a variety of way points. >> something that couldn't be done by accident. >> but there's enough way points in that part of the world you have only to fly in a particular direction. we do not know, sir, that it was manually or autopilot flown. >> okay, calm down. >> there's a lot we don't know. i think when he says that we know, it is just from the information given out there. >> i'm not budging on this. >> cut the man some slack. we want him to come back. >> the delegation traveling to beijing to speak to the families about the ongoing search with no debris. the bluefin not finding anything yet. what additional information can they provide? >> i don't think they will get much information. i'm going to agree with richard

quest, because i think he is right. i don't think we know anything. i think we only have filtered information from the malaysian government and boeing and inmarsat, who has a relationship with boeing. all of which have conflicts of interest. only way we will know any facts and there's no reason why we can't have them is to get the raw data. there's no excuse for not giving that to the families. that is what the families want and that's what they deserve. all of those questions would be answered if the families had the tapes and the downloads on the radar and satellite imagery and independent people could evaluate and i think richard made a good point. we don't know if this was intentional intervention. we don't know what caused it is true it made these turns, what is the reason the aircraft did that. i think it is speculation at this point. >> robert, it is your night tonight. the other night it was jeff wise's night. everyone gets a night where they get beat up here. jeff wise, you can tell him. >> can i jump in? >> yeah. i want to come to the aid of the afflicted here.

i strongly disagree with richard quest. i love disagreeing with richard questioning in general. here i think richard, you are off base. the plane clearly did not turn itself on a westerly heading. it did not skirt the thai border the way it did. this is clearly under human control. i don't think that that is ambiguous. there's no accident that -- look, the triple seven is an incredibly robust plane with a fantastic safety record. have to side on the side of those who say -- >> as the ringmaster, that's it for now. when we come back, a team of experts will answer your questions. more on this coming up. honestly, i'm pouring everything i have into this place.

back now with my experts for a lightning round answering your tweet questions. i will start with jim. it's a question from john. he says, has any pilot from mh or the search countries flown the route the plane took. it couldn't hurt and may help to spot it. >> yes, that's correct, if we knew the exact route the plane flew. but then again, this situation, i agree with rich that we don't know. there are a lot of things we really don't know. we have a good reason to believe, however, that somebody

was flying that airplane. >> all right. this is for karlene. it is from phillip. was there any kind of air marshal on the jet? >> i have no idea if there was an air marshal. i highly doubt it with malaysia. >> okay. bill, a question from ashley. ashley says, "if and when mh-370 is located what are the chances of recovering the victims and how?" >> well, for 15,000 feet of water, that's going to be very difficult. probably the number one priority still has to be the flight recorders. until we find those we have nothing. >> here's a question from james. it says, "why not get a u.s. nuclear sub involved that can stay on station for months not affected by weather. great sonar equipment." >> that's a really good question. i don't know the answer other than that it probably would help and might be a question of resource allegation. >> jeff.

is the sole reason it is believed that mh-370 traveled the southern arc because it didn't appear on the northern countries' radar? >> that, that certainly is a reason that's been cited but the main reason is that inmarsat released an analysis that it found it was more probably that it traveled in the northern route than the southern. >> this one says ask panelists do they believe there are geo political reasons why data exchange bad and what can be done by law. >> i'm sure there are geo political reasons we are not getting information from the vietnamese controllers. in fact, if you recall, we heard stories of how jets were scrambled. if that occurred there would be reports from other radio systems and there would have been chatter around the world, presumably in the u.s. and we're not going to release that kind of military information. so, i don't know any law that can be passed to do anything about it. >> in short on this issue, no one has come to the table with

clean hands. everybody has withheld something but they believe they have given enough to make the case they have to make. >> we'll be right back. , but they're gonna fall in love, get married, have a couple of kids, [ children laughing ] move to the country, and live a long, happy life together where they almost never fight about money. [ dog barks ] because right after they get married, they'll find some financial folks who will talk to them about preparing early for retirement and be able to focus on other things, like each other, which isn't rocket science. it's just common sense. from td ameritrade.
