>> iran and china have a close relationship and boy, are the chinese quiet. >> thanks for your time tonight. that's all for us. don lemon has the latest on the "new york times" reporting. -- captions by vitac -- www.vitac.com >> this is a cnn special report, the mystery of flight 370. i'm don lemon. we're going to begin with breaking news from the "new york times" tonight. they are reporting that the flight turned to the west at the direction of a computer system that was likely programmed by someone in the plane's cockpit. another piece of evidence that points to the involvement of the crew into the disappearance of the plane. as far as we know, no one on earth has heard anything from the 239 people on board since then. but there are so many questions. we have been hearing from you since it happened. and tonight for the next hour we're going to answer your

questions. like what are the odds the pilots are in this together? why do you trust that pakistan has no radar evidence of the plane? and what if the plane is in the hands of hijackers? and i want to go to our breaking news. here now with that is michael smith, one of the reporters on that story. >> we are reporting that the first diversion that the plane made on its path was done -- was done by a computer system on the plane. and not done manually by anyone on the plane for that matter. what happened was is that someone on the plane put into the computer system that sits between the pilots a new direction for the plane to go in and that is why the plane moved. we believe this is significant because the investigators

believe it's significant because it shows that whoever did this had some expertise in flying. this was not just someone on the plane who grabbed the controls and moved it. >> this reinforces the belief that this plane was deliberately diverted in some way perhaps by the captain or the co-pilot on the plane. the last person to speak was the co-pilot who said "all right, good night." with so much information, how reliable is the information coming from the malaysian government in your assessment? >> the malaysian government has had a bit of problem with their credibility. for the first week they didn't really say much. and they came out on saturday and they said that they did believe foul play was behind it. and today they reversed something they said on sunday. in a sense they didn't do any favors by not saying anything initially. we get drips and drabs of

different things. but when there is so much we don't know we are left -- we're left in the dark on a lot of things. >> michael smith, thank you very much. i want to bring in jim sciutto. what can you tell us? >> the defense secretary chuck hagel reached out to his malaysian counter part one saying that the u.s. remains committed to the search, willing to give the assets necessary, the planes and ships, to make the search. but the u.s. is retasking its ships and really more its airplanes to focus on the southern indianian ocean down there. and it's been cnn's information that when you speak to u.s. officials, it's their focus.

it's their feeling, their stronger feeling it's more likely the plane is in the indian ocean rather than that path up north into central asia where the possibility of landing the plane. and the focus is with the p-8 poseidon. and that's where the u.s. will focus. >> what increased security alerts are we seeing tonight? >> the one country that has done something is israel. it is requiring airlines to identify themselves earlier than normal. you travel to israel and i have been there a number of times. it's the country with the most strict security on the ground when you are flying airplane, interrogations, questions, searches and strict procedures for airliners approaching. they have to identify themselves further on the chance that this

plane has been hijacked for later use, perhaps in an attack. the u.s. and i have spoken to people on capitol hill including members of the house intelligence committee, is the u.s. considering any measures. this conceivably exposes security fears here. it presents the fact it could happen here 13 years after 9/11. including what a pilot can do in a cockpit. could the pilot turn off the transponder. that is a possible change going forward. that is things they are looking at. you can be sure there will be debate about new measures here as well. >> you have done so much to help us with this story. i want to bring in cnn's richard quest. also with me is jeff wise, the

author of "extreme fear: the science of your mind in danger" and mary schiavo. and chuck beatty served in delta force, the fbi and cia. and david stupples with me. jim tilmon as well. a retired american airlines pilot. thank you all. this hour is for you, the viewer. you have so many questions you have been sending us and we hear you. i want to go to robert ray. 7425 at twitter. if the satellite track that plane for six to seven hours why don't they know where it went down? something does not make sense.

david, do you think that the plane could have been tracked by satellite? why? >> it is possible that the plane would be registering with the satellite but the communication with the satellite is 23,000 miles up in space. it's geostationary and it really can't find direction or position of anything -- say it's there, but it would not be able to give a position. >> richard quest, pakistan, indian, myanmar, thailand, indonesia all say they did not detect the airliner on their radar. how reliable is their radar? >> we don't understand fully the capabilities of those individual companies. some will say it's evil metal and not accurate. but if you are talk about india and pakistan and their borders and coastline, then there are

certain areas if those countries are saying they did not see anything that is a fairly high degree of certainty. kazakhstan has said there is no evidence of anything breaching their air space. >> i supposed a similar question to the "new york times" reporter about the information from the malaysian government. does the u.s. believe we are getting briefed in the latest information from the countries involved at this point? >> early on there was reluctance to share it. that wasn't just u.s. officials. you hear it and still do from chinese officials and other countries involved. the feeling is it is getting better now but it's i think there is a question out there. because as kazakhstan, pakistan and others say there's no way this plane passed through our air space there is a reluctance on the part of some of these countries to share the full

extent of their capabilities because you have a lot of disputes between these countries, rivalries, border disputes. and the tensions are still there. so they don't want to make it exactly clear how far and clearly their satellites see and how extensive and well monitored their radars are. that hasn't gone away. the question is, is everybody sharing with everybody? and that's an open question. >> this is an important question i want to ask. i'm going to pose it to jeff wise. a lot of people tweeted about this scenario. darrell b. said is it possible that mh 370 could have shadowed sia 68 to avoid radar direction if it went north. >> there is a theory that flight 370 could have linked up with a singapore airlines flight around the time it disappeared and shadowed that plane on its route to avoid radar direction.

>> you know, we came across it and looked at it. i feel it sounds like it is plausible. it matches with the data you can find from the online flight trackers. it sounds plausible but at this point it seems like to much conjecture. if i could touch just on what the first viewer asked which was about the pinging. this is a major point largely overlooked. the satellite nav system was pinging. was checking in with the plane's sat/com system. we know this happened at least four times. the malaysian government made a big deal about releasing that data on saturday morning and releasing this arc you have on the wall behind me. that is the most significant piece of information so far. and why haven't they released the previous pings. if we could see where the arcs

lay earlier in the flight it's hard to know for sure but it might give a clue as to where this thing is. >> i want to get back to the viewer questions. go ahead. >> on this point, sources close to singapore airlines have told me that they can find no evidence of this. >> the shadows. >> i believe aviation sources also say that they are not look at it. they don't give it any credence. >> good. thank you for that. this one i pose to jeff beatty. we'll talk a little bit more about the satellite season. he says, pakistan confirmed they have nothing in their radar. did we get similar confirmation from all countries on probable route? mr. beatty do you know about that? >> from what i understand we have not heard from anyone yet

and we may not get complete information because people are going to be reluctant to share what their true capabilities are. as jim was talking in his lead in. there are people who have had fights with each other in the past. but if i could add one quick thing, don, i see in what mike smith and what jim reported if i'm a family member i see some encouragement here. because if you are the pilot and program something into the computer and the aircraft begins a turn you don't need to fly another four or five hours to commit pilot suicide. this takes off the table a little bit in my mind one of the scenarios that probably families were most fearful of. so some good news there one can make an inference of possible good news. >> mary you want to follow up on that?

>> in a different way. if the pilots are able to program in the waypoints and codes into the computer they are still coherent. whatever happened has not rendered the plane unflyable. they can still put things in the computer. it does -- i'm a skeptic. i want to see evidence and put together the pieces of the plane but it cuttings they were coherent and knowingly did change the route of the plane. >> kayla says why do we trust pakistan when they say they have no radar evidence of the plane? here's my question to you, david. if a plane is looking to fly under the radar in that part of the world is it 100% necessary -- is it absolutely 100% sure that a plane cannot fly under radar in that part of the world. is the radar in that part of the world that strong or weak enough to allow that?

>> you have to look at the radar range itself. when the plane was first lost it was at the extreme end of the radar system from malaysia. so we are talking about 250 nautical miles and the aircraft was at 35,000 feet to. fly under the radar it will have to fly -- know the range of the radar and then fly to the height for that range. so as it's approaching, say, pakistan, it's going to have to go lower and lower and lower. and i doubt a plane of 200 tons could get under the radar. >> jim tilmon, i promise we will get you in. does the united states believe we are in a threat right now because of this? that we are vulnerable? >> well, they don't when you speak to u.s. officials. one reason they don't is they have not established a terror

link to this attack. they haven't ruled it out but they haven't established that connection. they are not triggering the reactions we would see if there is a terror link there. but lawmakers are looking at possibilities to close some holes here. when we have a whiff of a plot out there. you remember the tooth paste tube explosives or refined shoe bombs, things we have been reported in the last few weeks. you know, they start to make adjustments in security screenings, et cetera. if this turns out to be a plane commandeered by terrorists that is not just a whiff of a plot. and i would echo your other guests. the thing about this flight computer, the story in the "new york times" is it begins to eliminate other possibilities.

sudden incapacitation of the crew. plus the idea you had a yahoo walk in the cockpit door and try to commandeer the plane. >> everybody stick with us. jim tilmon, i'll get you in. i want to talk more about this in a few minutes. when we come right back, what do we know about the pilots of flight 370 or any pilots, as a matter of fact? we're keeping your answers -- keep sending your questions at #370qs.

nobody who has ever flown on a plane wants to believe that the pilot and co-pilot aren't doing everything they can to keep the passengers safe. are we flying on blind faith? rosa flores has put together everything we know about the pilot and co-pilot of flight 370 and what airlines do to check pilot backgrounds. >> anxiety erupting. the search growing. >> our priority is to find the aircraft. >> reporter: and new clues surfacing like this video of the pilots as the focus on the cockpit of malaysian airlines flight 370 intensifies. the homes of captain zaharie abdul shah and fariq abdul hamid

searched by authorities. they seized this flight simulator. raising questions and feeding theories about what it was used for. >> you can compare one flight to another flight to see if you improved as far as the ability to maintain altitude or stay on the glide slope during descent. so it's possible that the flights he was taking on the flieblt simulator would be recorded on that system. >> also on tape, surveillance video posted on youtube showing the captain and first officer going through airport security. cnn cannot confirm the authenticity or the date of the video.

the captain's family posting this tribute online, describing him as loving, generous and supportive. neighbors of the 27-year-old co-pilot also talking, saying his community is praying and maintaining hope but there are troubling photos from the co-pilot's past like this from 2011 showing him and two teenaged passengers in the cockpit during a flight from thailand to malaysia. >> i was upset that with the fact that they were doing it was something that happened quite often. >> i was shocked to see those pictures. it was inflight, as i understand. it was during the flight. i can't imagine breaching the cockpit door for anyone other than the flight crew. >> reporter: passengers put their lives in the pilot's hands most of the time not knowing a single thing about them. who is looking at the flight

crew? malaysia airlines say pilots are screened, undergoing psychological tests. >> going forward we will look into all this. >> in this country, david soucie says that oversight of pilots mental health is left to an honor system. >> there is no one that does an independent evaluation unless the pilot himself says i've got issues. to me that seems backwards. that doesn't seem like an effective way of understanding and monitoring the psychological wellness of an individual, particularly someone in charge of that many lives. >> reporter: in the case of malaysia airlines flight 370, 239 lives in the hands of a flight crew now under scrutiny. >> rosa flores is here now. we got tweets about screening of pilots.

here is what one says. he asks, how can airlines not conduct periodic psychological tests or check ins on pilots after they're hired. couldn't hurt. what did you learn about that? >> here's our david soucie put it do they get physicals every year? yes, they do. the sigh psychology part could be improved. it's up to the pilot to come forward. who in their right mind would come forward and say i can't fly a plane when it puts their career and financial future in jeopardy. >> thank you for that. i want to hear what my experts have to think now. richard quest, he is here. raffi ron is the former director of -- and richard i want to

start with you. you can speak endless about what she was reporting on. >> in terms of all pilots go through recurrent training every six months. the airlines are very aware particularly in the recession we have just been through, extra stresses, marital problems, anything like that. there is an entire structure of reporting anonymously. and one very senior pilot at an airline who is responsible for the training and management of pilots put it this way. we tell pilots they can come to us if they've got a problem. if they have a psychological issue. they won't lose their license permanently but they will be medically unfit but it's they know they will have a paycheck. >> raffi you were the director of security in tel aviv. how are the pilots screened there? >> there are two categories.

one category is your own pilots. in the case of israel it is israeli pilots flying israeli carriers. and the other category are foreign pilots that they bring airplanes into your territory and your airports. one on the first category, you can take the issues and take a policy and implement it. the second category is almost impossible to touch. and most of the problems occur in the second category. because the first category of your own pilots is the regularly monitored as a strong background and environment that would indicate issues that may develop. and if somebody is either suffering from mental issues or not necessarily the case of israel but in other countries,

goes through a radicalization process and they become a threat, as long as is it in your own territory you have your intelligence. you have your access to people in the pilots environment. but when it comes to foreign pilots, you have zero. you have to rely on whatever you are being told by the country that owns that carrier. >> the standards aren't the same all over. i want to read a question from jen durham. can pilots choose their own co-pilots. what are the real odds that the pilots are in this together. can you answer this? >> from what we know the pilots did not ask to fly together or ask to be with each other. can they ask to be with one other, yes. but i want to talk about the testing, the psychological of

the pilot. in law enforcement, for example, they give psychometric testing to someone before they give someone a gun. a common one is the mmpi ii. it is given to people to see if mentally there is psychological issues or personality issues or mental issues. this is something we may see now coming for pilots. there's a wexler scale, the rorschach and in certain people who are responsible for people's lives before they are in the position to fly a plane or give them a badge or gun. it's dangerous we do not do a psychological test of individuals before they enter a profession. who is going to say i got problems, don't give me the job. or that person may not know they have problems.

>> thank you. richard quest. stay with us. when we come back i want to talk about some of the other theories out there. some may not be as crazy as they sound. and we are answering your questions tonight. tweet us using the #370qs. and this will be your premium right here. sorry to interrupt, i just want to say, i combined home and auto with state farm, saved 760 bucks. love this guy. okay, does it bother anybody else that the mime is talking? frrreeeeaky!

so with all of the worldwide attention to this story it's

hard to believe this is only the beginning. but how will this end? will we ever get any answers. jim, my first question to you. i promised i would get you in. this is from advanced security on twitter. is it possible someone stole the plane to use later on our in a terror attack and wanted us to all believe it crashed in the ocean, jim tilmon? >> yes, that's possible. but there's so many possibilities. i mean, we just have to put this on a long list. yes. that is possible. i'll just say that much about it. >> could this airplane or airliner be taken for another purpose? is that why no one is taking responsibility and their mission isn't complete yet, possibly? >> well, that certainly is one of the possibilities.

there is about three other scenarios i would like to just highlight. one of them could be a high-value cargo. the aircraft might have been taken for a high-value cargo. that could possibly be high-value people on the aircraft or that cargo could be something of great value in the hold. the second one is in the past we have actually had aircraft become a venue for murder. i know of three cases where, for example, manuel noriega took down someone that way. and we had egypt air go down at the hand of one of the crew members, killing 30 egyptian officers on board including two general officers. so it could be high-value cargo. it could be murder and finally there is always ransom.

we had a connection between the pilot who is a strong supporter of the major opposition leader. and he was arrested just before this flight. perhaps the pilot felt in the past people have held aircraft for ransom for release of prisoners. so there are many possibilities still out there. and each piece of evidence takes some of them and make them less likely. the pilot suicide is a little less likely. >> this idea of hijacking. i want to stick with that for a moment. are the authorities look at the scenarios should the plane be intact and in the hands of hijackers. >> i hope they are looking at that. there were so many lessons learned after september 11th. but one thing that was clear in the investigation following september 11 and that was the

plot, the hints, the clues it was imagined and imaginable. we had a lot of intelligence and as soon as 9/11 happened, evidence started pouring in. i got two key pieces of evidence delivered anonymously. everyone wanted to help. here we don't have that. which is disconcerting. so the governments around the world have to dig deep. there doesn't seem to be any information forth coming. i call it an eerie silence right now. >> this may be out of the blue could it be possible that the plane is in north korea? >> the quick answer to that is no. if we give credence to the report from the malaysian prime minister on saturday it's either in the north or the south along these two arcs. north korea is not one of those two places.

we do know a few things confidently. of all the scenarios that exist, north korea is not one of them. >> when you are talking about north korea, david is that a possible? >> i don't think so. it was turning west over malaysia. if you believe that information that's the way it was flying. if it was flying up the other way then it would have been spotted by vietnamese radars on its night to north korea. >> stand by, everyone. coming up, a boeing 777 vanishes. in today's day and age in this technological age, is this possible?

most of the questions is about cell phones. i'm aware of it from reading your questions. we're going to take your questions and try to answer them coming up and make sure you tweet us using the #370qs. my lenses have a sunset mode. and an early morning mode. and a partly sunny mode. and an outside to clear inside mode.

back with me now are experts richard quest, jeff wise, mary schiavo, jeff beatty, david stupples. what do you think all the questions have been about? technology and cell phones. here's what cindy cole says. what have we been told about the absence of cell phone contact, no photos, texts, calls, that is incredible. >> the questions come into two distinct questions. on the one hand why have we receive nod information from anybody and secondly why can't you use cell phone technology to find. and some people are calling cell phones and they are ringing. the family and friends are calling cell phones and it's not going to voice mail.

it is ringing. these are cornerstone issues. >> mary, we have talked about this and as i told our viewers at the beginning of this program we have been following this step-by-step, minute by minute. we are on air reporting it. but not every viewer is doing that and paying close attention to every single detail. we are getting a lot of questions about cell phones and the families holding out hope and people holding out hope because the cell phones are ringing that means these folks are still alive and they are well. >> the first question is why not the calls from the plane or to and from the plane? this plane did not have on board wi-fi and cell phone service. they would have to be near a tower. the plane passed over malaysia and that was a possibility. but it would have had to hit a tower just like anyone else on the ground or being lucky to get a tower.

and then actually some phone company officials have said that the cell phone ringing was not indicative that the phone was still working but ringing through to the area or the switching station to go ahead and meet the cell phone. it did mean the cell phone itself was working. >> jim tilmon this is for you. this is your expertise. this is from john parker. he says could pilot depressurize plane to cause passengers to pass out? jim? >> yes. it can deprive the cabin of oxygen. and they don't have to do it for a very long time because you just cannot survive but just a matter of minutes without oxygen. you go into kind of a hypoxiated sleep. the pilots can put on a full face mask and they can indeed breathe 100% oxygen for a while.

it's far-fetched and awful to think of but it is possible. >> it is. so we heard that the possibility of the plane had gone up to 45,000 feet. if it could do that with the weight and you know, with the equipment it had on board but it's the question is, wouldn't the oxygen masks be deployed automatically if that were to happen in the cabin, jim tilmon, or could they control that from the cockpit and the pilots only have the masks and the passengers don't. >> i think the masks would drop automatically. they do when you go through a certain altitude in the cabin. but you have a tiny canister in each one of those overhead bins and they are your oxygen generators. they only run for a relatively short length of time. that's why the protocol is if

you have an oxygen problem you immediately go into a descent to get into breathable oxygen and that's a pretty good drop. that's a controlled dive to about 14,000 feet. >> okay, jim. this is for jeff wise. is there any possibility of the plane being intact at the bottom of the ocean with no floating debris? >> well, if it was in one piece that would mean the pilot did a quiet landing like pilot sullenberger. but you would get the life rafts which are equipped with emergency beacons. it's that or you do a supersonic descent where the thing breaks into a million pieces. that leaves millions of tiny

pieces floating around. it's hard to imagine a scenario where you ditch or crash in the ocean without a trace left. >> everybody stick around. richard and i have come up with this. you would not believe how many questions we are getting. i have got hundreds, if not thousands during this broadcast. we're going to go through the twitter feed and we're going to ask the questions that you are sending us to our experts here. make sure you #370qs.

you have time to shop for car insurance today? yeah. i heard about progressive's "name your price" tool? i guess you can tell them how much you want to pay and it gives you a range of options to choose from. huh? i'm looking at it right now. oh, yeah? yeah. what's the... guest room situation? the "name your price" tool, making the world a little more progressive.

we're asking and answering some of your tough questions tonight about the missing flight 370. back with me are richard quest, jim tilmon, jeff wise, mary schiavo, jeff beatty. this is from dave o. it is an interesting question. is it possible that mh 370 went west to africa, in particular, somalia. let's ask david stupples. >> i don't think it had enough fuel to reach somalia and it would have been tracked. >> jim tilmon could a passenger with a laptop hack into the

cockpit computer? >> no. i don't think so. >> a question for mary here. from sarah. could the disappearance of flight 370 be government related? >> well, a hostile government possibly, yes. they would have means. >> jeff wise, did they search the flight path or automatically think it went across the world? that is from thomas tompkins. >> i don't understand the question. >> what are the possibility that this is a black hole? there are conspiracy theories about that. you never know, it could have landed in myanmar. mary schiavo? >> we don't have a lot of pings to go on.

if it's near the flight path it's possible. we have a few data points. >> jeff beatty i would say they are hijacked and if they are on board the family would have come to meet with the rest of the family -- the pilots family. there were reports that the pilots family moved out of the home. but they would have gone to meet with them already. does that even weigh on this investigation? >> i don't think so. if this was an elaborate hijacking operation i think there is an opportunity to put forward a major reward program. i haven't heard much about that. >> i think this is a very interesting question. you people are asking why are you asking about the passengers. why aren't we looking at the flight crew -- why are we looking at the flight crew and passengers? >> well, because we look at past history and in past history

that's where most of the threats have come, from a flight crew, passengers in 9/11. >> jim tilmon question from michael. is it possible to lose all flight controls and have the 777 take over on the last program vectors? basically, if things went wrong would the plane just automatically default to its last flight? >> kind of yes and no. it's not like the airplane has a brain of its own. if it was programmed for a certain kind of heading and altitude and sort of thing, and then nobody put in a new input it would continue that until it ran out of fuel. but i think that is far-fetched. i'm sorry. >> thank you very much. we'll be right back. don't go anywhere. still taking some of your questions. we asked people a question,

how much money do you think you'll need when you retire? then we gave each person a ribbon to show how many years that amount might last. i was trying to, like, pull it a little further. [ woman ] got me to 70 years old. i'm going to have to rethink this thing. it's hard to imagine how much we'll need for a retirement that could last 30 years or more. so maybe we need to approach things differently, if we want to be ready for a longer retirement. ♪

back now. richard quest, jeff wise, mary schiavo, jeff stupples and jim tilmon. >> how is it possible for a plane to simply vanish? seems like a magician's trick to me. >> when planes cross the ocean they often vanish.

we depend on vie mare radar. when the radar doesn't cover it, they vanish. >> jeff beatty. >> it's a big ocean and i would have to say if it went down in the ocean they may not find it for a long time, if ever. hopefully it went down somewhere on land. we have a better chance there. >> jim tilmon. >> i agree with the last person. the chances of finding it at the bottom of the indian sea is slim. i pray they are all right. >> why was malaysian air choosen for richard quest's story a few weeks ago? >> that was the part of the world that we were filming in and it was an airline with issues about restructuring. >> and you happened to fly with that co-pilot? >> pure luck. we have got in sheer numbers of

tweets shows the huge interest on this. >> i have to run. i want to thank all of my guests tonight. tonight. we'll see you here soon on cnn. -- captions by vitac -- www.vitac.com tonight in the united states. we have new developments tonight in the disappearance of malaysia airlines flight 370. the best evidence suggests the boeing 777 flew into one of these two areas and was still being tracked by a satellite more than seven hours after takeoff. that's hours after the first officer's seemingly routine sign off essentially just saying good night. hours after the plane's radar transponder signal vanished, hours after acars stopped sending data, hours after it possibly soared to high altitude and then plunged 20,000 feet and then climbed again.
