>> their lives are changed, and we're educating men who have been arrested for soliciting women. >> i'm not here to make you feel plik a piece of [ bleep ], but that's somebody's daughter. >> we really are raising an army here and this is a battle. it's not okay to buy and sell us. we're not for sale. hello again, everyone. i'm fredricka whitfield. welcome to the cnn "newsroom." potentially significant new details about the events leading up to the disappearance of flight 370. here's what we know right now -- malaysia's prime minister says the cockpit's signoff to ground control, which you recall was "all right. good night," was said after the plane's communication systems were disabled. and that means whatever incident happened on that plane was already happening when ground control heard that message. malaysia's prime minister also

says all of the evidence so far points to the likelihood that someone inside the plane deliberately took the plane off course, and the investigation will now focus on the crew and passengers. this is video of police leaving the home of the plane's copilot. the pilot's home was also searched. u.s. authorities say they continue to review the backgrounds of the crew and the passengers, but so far have found no links to terrorism. and satellite signals now indicate the plane may have been airborne several hours after losing contact with ground control and radar shows dramatic changes in altitude during that time. fluctuating between 23,000, 30,000 and 40,000 and 45,000 feet. officials have concluded the plane likely flew along one of two distinct paths. the first, north all the way up to the border of kazakhstan. the other south towards the southern indian ocean. so let's dig now a little deeper into this development surrounding the timeline of events of that airplane.

richard quest joins us now by phone from new york. so, richard, that the communication system was disabled and that, according to malaysian authorities, this voice was able to say, "all right. good night." you were telling us earlier that's a radio frequency. that's radio conversation, and that's why that information was able to be transmitted, but is it possible that that pilot, if that was the pilot's voice, didn't know that the communications system was disabled? >> well, when you say communications system, you're talking about a particular communication system. about the acars system. the p.m., malaysian p.m. said this morning that had been disabled, as they believe it had been disabled as it went out across the east coast of malaysia. yet several minutes later you have the transponder switched off, but you do have the hand over, and what i think we must emphasize here that at times

we're dealing, and here, this is one of them, with conflicting pieces of information. it may all become ridiculously clear when somebody tells comes out tomorrow and says, well, no, he didn't say, all right, good night. that was a mistake. or something else happened. you know? for example, one person's just e-mailed me to point out the, "all right. good night," it should have been a full readback from the pilot, with the name of the aircraft, malaysia 3-7 d-0, acknowledging what he just heard and then saying, all right, good night. but these are minor details, and conflicting details in the jigsaw that will put together the piece, of the total picture. at the moment, what i'm seeming to suggest there is a difference in the timeline between what we've heard what we know, and then explanation for what happened. >> and is it possible, you know,

in the world of whiting that all right, good night, could have been a code for something else that perhaps could have been in way sort of a mayday? >> no. i don't believe so. and if it is, it's not -- nothing that i've ever heard of before. one would have expected a full readout to be something along the lines of, malaysia, 3-7-0, contact, whatever the sequence was and he would have said the frequency he needs to contact vietnam, malaysia, 3-7-0, good night nap would have been the normal way. we don't know, i think whoever was revealing that all right, good night, didn't give us the whole readback from the pilot, and there's no reason they would, because there would have been details in it, ultimately, this was a, there is this question of what happened after the acars system was disabled, which the prime minister said, after that happened, before the

transponder was switched off, there does seem to be this gap of time and the question will be focusing upon what was going on just before, during and after. >> and still unclear, because it has not necessarily been revealed from those malaysian authorities, the same ones that gave us this bit of information is whether that voice is that of the pilot or copilot. >> no. because until now, we had no reason to question whether it was or otherwise. until now this was a perfectly normal transmission from one air -- from an aircraft going from one flight zone to -- from one piece of airspace to another and entirely normal. even the all right, good night. sounds perfectly normal. look, i'll qualify that with one point. fredricka, if the pilot only said, all right, good night, then that would have both been

wrong and sloppy because he's supposed to do a full readback of what's just been told so there's no confusion. so i've made the assumption, erroneously, maybe, that we've been left out of something of the story. if he just said, all right, good night, then he -- i'm surprised the air traffic controller might have said to him, can we have the full details, please. >> richard quest, thank you so much. we'll be seeing you momentarily on-set. i'll let you go for now. thank you so much. so what does this new information mean for the investigation in this search for flight 370? i want to bring back aviation lawyer and pilot and aviation engineer arthur rosenberg. good to see you. so -- >> how are you, fredricka? >> based on the information we're getting from malaysian authorities, are you anxious to hear whether there was more to this message? all right, good night? or is it alarming or disturbing enough to you that it was just simply all right, good night, after the communication system was disabled? >> all right, good night, is a

game changer in this investigation. so i think we just have to back up a little bit. we have a plane that took off from kuala lumpur in the middle of the night. the middle of the night is the least traveled time for airplanes, the least time that air traffic controllers are manning the stations. things are much more relaxed. 45 minutes into this flight we now know from the prime minister of malaysia that it was either the transponder or the acars system. i'm not sure which one, was turned often, and then you have a communication, which is, all right, good night. now, with all deference to mr. quest, i disagree with that, with his analysis. i they was an atypical and improper message from the -- from the plane to the controller. what he should have said is, malaysia flight 3-7-0 and then repeated the frequency to the

handoff to the vietnamese prol controller bp but that was not done. an ominous foreboding of what was to follow. what happened happened rapidly. a plane that immediately turned back to the southwest. a plane no longer being followed, identified with transponder codes. you have a plane which was paintsed with primary radar hits and the information heading to the west coast tv towards the andaman islands and this plane was flown either on autopilot or by hand to those waypoints. it was flown intentionally and with deliberation and with great skill. the altitude deviations which we've talked about a lot, i don't give a lot of credence to, because the plane was already about couple hundred miles away from the nearest radar station. the farther you get away from radar, the less accurate the

altitude deviations are, although there my have been altitude deviations, but i say that the prime minister's information that whether it be most probably the transponder was turned off before, all right, good night, is an absolute game changer, and it implicates, it implicates, whoever was in that cockpit. now, it may have been the flight crew. the flight crew may have been disabled. it may have been some passenger terrorist who moved forward into the cockpit. we don't know that yet. perhaps if someone listens to that voice very carefully, a loved one, someone who knew the captain or copilot, we can figure that out. for now that is an absolute game changer, which tells us that this plane was deliberately commandeered to another location. >> all right. arthur, hold it right there. i want to talk to you more about this game-changer moment in your view. we're going to take a short break and when we come back we're going to talk more about the crew, what more investigators can extrapolate from that transmission, and what might be next in this investigation. after this.

all right. the search for malaysia airlines flight 370 is widening, the investigation into how it van h vanished now nine days ago. focusing on the crew and passengers. video of police leaving the home of the plane's copilot, she is 27-year-old man, recently started copiloting a boeing 777. the spipilot is a 53 prl-year-o pilot, his home also searched. joined in 1981 with more than 18,000 flight hours. bring in an attorney from washington and cnn aviation analyst mary schiavo in south carolina. all right, to both of you now, mary, you first. when you hear that there is a change in the sequence of events, that the communication system would be disabled, or

switched off, and then you hear a voice say, "all right. good night," are you convinced that it is the pilot, given that we just talked to one pilot before the break who was saying usually there is a whole lot of other information identifiable information for the pilot before they say good night? is this -- how strange is this to you? >> it's strange. but richard's right. ordinarily you have to do the readback and you have to do the readback because, and it's part of air traffic control, because sometimes pilots get lost in the hertz. meaning they have the wrong frequency and switch over, there's not, no way to contact them. but air traffic controllers and pilots alike get sloppy, particularly at night. i've had air traffic controllers wish me a happy birthday before and people don't usually get wound up about it. the second thing is, the fbi and law enforcement agencies around the world have a very reliable way to do voice identification. if they haven't done it already, they should already know worth

that's one of the pilots' voices. the equipment is easy to come by and reliable. here's the third thing. the third thing is every airline trains on a verbal hijack code as well. so malaysia airlines ought to know whether or not the pilot said this, these codes, that they do and only they know what their words are. so if he had been hijacked at that point, presumably he would have said something, because he the verbal chance to do so. all right, good night, is not pilot lingo. so at this point, should have found out if its his voice. reliable ways to do it. the readback missing. maybe we just don't know about it. that was odd. air traffic controllers don't bust you for it, third did he say anything malaysian airlines would know giving and indication he'd been hijacked. >> you're saying those jurisdictions would have to know the ling other, agreed upon that would be it? how would they know otherwise? >> malaysia airlines would train

their pilots. ma lash shaye airlines knows whether they trained their pilots on this. i assume ewas, this this pilot, he has so many hours. and who is investigating what the airline did? a very important clue. presumably they know all this by now. i don't know. it's kind of a mess. >> so, mark in your view, are you in agreement with arthur rosenberg, whom we spoke with earlier, who said this is a game changer, to have this kind of information is a game changer? although we already knew from a malaysian authority, malaysian authorities, they said they believe there was a deliberate action that had taken place. it does this just underscore that? >> with all respect to mr. rosenberg it's irresponsible to suggest it's a game changer or ominous. i think tall does is add to the, this crescendo of speculation. there are air traffic control tapes. air ground tapes, that the

malaysian air traffic control authorities have. they can replay those. that's where they get the final words. they can easily determine exactly what's on that transcript and said between the aircraft and ground up until the pound they discontinued talking an the frequency. so i think that mary is absolutely right. i spent 44 years doing this and marcy absolutely correct. pilots are not only always presis in their phraseology. air traffic controversials are not always precise in their phraseology, and to somehow suggest that the words "all right, good night" are ominous or game changers, maybe they are, but to suggest that does a disservice to the families. is does a disservice to be airlines and to the passengers. >> oh, mark, not to pick a fight or anything, but arthur rosenberg is still with us so we've brought him back into the fray here. arthur, you still feel very

confident about your yourself of the terminology that this is a game changer, even though malaysian authorities had already said at, earlier in the, wee hours of the morning they thought this was a deliberate action? but now getting this detail about, all right, good night, in your view, heightens it. why? >> well, with all due respect to mr. dondoorth i think he missesing point. the sequence of events is very telling. if you first have a transponder that is turned off followed by a very last communication, which is all right, good night, that is very, very telling. it means that whoever was in that left seat knew that the transponder was off. i'm not saying it was the captain or the copilot. the plane could have been

commandeered at that point. the point being they knew and had to be part of the sequence of events resulting in the commandeering of that airplane. that sequence, transponder off first, followed by that communication is the game changer. that's point. it's absolutely true that sometimes pilots get sloppy in their lingo, but i don't think that you can downplay that enough. you have a transponder, which was intentionally turned off. meaning they didn't want to be seen. followed by a very last communication, all right, good night. if i'm the captain of that plane, at that point in time, i'm saying, malaysia air traffic control, acknowledging, and then given the frequency to the vietnamese controller. i would repeat the frequencies to the vietnamese controller and move on. that's point. it's not so often, all right, good night, as it is the sequence of events, transponder

off followed by that, which implicates everything going on in that cockpit. >> arthur, hold it there. we'll continue this conversation a short break for now. fascinating sequence of events i'd love to hear all of your expertise on right after this. you know who you are. you can part a crowd, without saying a word... if you have yet to master the quiet sneeze... you stash tissues like a squirrel stashes nuts... well muddlers, muddle no more. try zyrtec®. it gives you powerful allergy relief. and zyrtec® is different than claritin® because zyrtec® starts working at hour one on the first day you take it. claritin® doesn't start working until hour three. zyrtec®. love the air.

welcome back. strange game changer. bizarre, some of the words used to describe now this new sequence of events, according to malaysian authorities. authorities are now saying that it is believed that the communication system was disabled on that flight 370, and then a radio transmission from a voes from that cockpit saying, all right, good night. what does it all mean? different interpretations about what may have been happening in that cockpit. i want to bring back three guest ice was talking to before the break. aviation attorney mark donbroth in washington, aviation analyst ma mary and also from new york. mary, to you first. what does this mean in your view? is it a game changer, just simply bizarre that this voice wouldn't use all of the code, the readback language, as you put it, in trying to communicate

with kuala lumpur before no one was able to communicate with it again? >> well, it doesn't sound bizarre until we now apparently know. now, who knows how the facts will sort out tomorrow, but at this point, since the transponder was turned off before all right, good night, and you can only a turn off the transponder in the cockpit, either one of the two malaysia airlines pilots said this and knew about the transponder turned off, if it was really turned off or just quit working. then, presumably they knew that happened before that last transmissi transmission. so, again, baaing to malaysia airlines. did you have a verbal hijack code, and was this it? and we don't want to know their hi jacke code. it's secret in most countries, and you should -- they really should be able to know at this point, because the pilots wool have known something was happening, and if they didn't and never trained for this what to do in this event, well, you know, it's just another reason to never set foot on malaysian

airlines. very poor operational practice, but something they should have known before now. i don't see it as new information. it's new to us. we didn't know the transponder was turned off before these last spoken words, and it's very easy through voice identification analysis to find out if this is one of the two pilots and i would have assumed good law enfirst mrcment would have done already. not a game changer but important, clues and telling. >> a variation of safety nets if a plane were to go off the grid, to go off track of something terrible happened, whether it be deliberate or accidental from the verbal hijack code, possibly being used to using the right kind of readback information. so, you know, mark, back to you, nen. vietnam apparently did have a conversation with malaysia to say, we haven't heard, you know from this jet. but might there have been another means in which whether it was entering that other

airspace to the west, whether some other jurisdiction would have been able to pick up that plane was in their airspace and try and communicate with that plane, or is that just a long shot? >> probably a long shot, because air space, whether over this coast on the country, is well defined in terms of jurisdictional issues. the handoff that is made between the malaysian air traffic control authorities and the vietnamese air traffic control authorities on that route is probably always made at the same time because of the radar coverage and who has jurisdiction over the airspace. so it's unlikely that we'd be looking at a third nation. my guess is, if there is a third nation involved they're involved in talking to the investigators. i think that one thing that's very important to keep in mind is that a lot of these questions can be answered even separate and apart from locating the aircraft itself. the air traffic, the air ground communications which is where they got the words, all right,

good night, are recorded. and those are available. and undoubtedly, the malaysian authorities have listened to them. and in this country, certainly, it's very usual, fredricka, for the airline and the investigators during an investigation to bring in, listen to to tapes, pilots, training pilots or other pilots from the company, who knew or who flew with both the captain and the first officer for the purpose of seeing if they can identify their voices. mary's correct. you can use voice spectra graphic analysis and so forth, but in terms of identifying the voices probably the best way is the simplest way. that's bring a pilot in who has flown in the simulator or on the line with them and say who is that? is that his voice? that is typically the way the ntsb, for example, identifies who says what in one of our cockpits in this country. so, so many of these questions about which all of us, myself included, are speculating, and all.

media is speculating, can be answered separate from finding the aircraft. it's frustrating that the malaysian authorities haven't been more forthcoming on a more timely basis to prevent this sort of speculation from going on. as i said before, at the risk of repeating myself it does an enormous disservice to the airline, to the families, to the crews' families, to the other employees on the airplane, the cabin crew. really, i think the time has come forward to address some of these questions and put to rest the speculation where we can. >> arthur, last word on this. >> yeah. i think in putting all the pieces of the puzzle together, i think you also have to look at what was said, the fact that the transponder was turned off before that final communication, and then take a look at what happened immediately after. facts which we apparently know now. we know that the plane from the primary radar hits turned left,

heading back in a south westerly direction. so when you put it all together. when you put the plane took off at a time of low traffic. air traffic control is at a very low level. you have a transponder which got turned off. you then have a communication followed by an airplane which basically made a 180-degree turn. all it says is, this was an intentional act by someone in the cockpit. we don't know yet if it was a captain. we don't know yet if it was a quo pilot. could have been someone who broke in, but it certainly is clear that this airplane was steered under the command of someone, and through an intentional act. all right. still setting the stage for those questions of why, and who, and what is next. thanks so much to all of you. appreciate that. mary schiavo, mark dumbbroth and michael rosenberg. much more coming up next.

we're getting potentially significant new details about the events leading up to the disappearance of flight 370, including this new development. malaysia's prime minister says the cockpit's signoff to ground control, which you recall was "all right, good night," was said after the plane's communication systems were disabled. and the order of those events suggests whatever incident happened on that plane was already happening when ground control heard that message. there's so much to talk about, i wanted to bring in our panel of experts. captain bill savage, a former 777 pilot, with 30 years experience, who has flown extensively in that region. commercial pilot rob mark, pilot and aviation attorney brian alexander and arthur rosenberg, aviation lawyer, pilot and aviation engineer.

good to see all of you, gentlemen. >> good afternoon. >> good afternoon. >> so mr. savage, i want to ask you first. you know, given that this information is being provided by malaysian authority, that these words, all right, good night, have been now conveyed publicly, and malaysian authorities have already said that they do believe that there was a deliberate action taking place here. does it frustrate you at all that they wouldn't first try to identify whose voice that is, so that it is not presumed that it's the pilot, because it very well could have been someone else too may be commandeering that plane? what are your frustrations or how are you enlightened by this information? >> well, it's interesting that there was such a short signoff that did not include malaysian 370 heavy, which is pretty much the protocol we use when either checking on or checking off a station, and it also would

indicate, again, the timeliness of malaysia giving us this information, but it's interesting to me that there's one other way you could turn off this equipment and that's by pulling circuit breakers in the cockpit which would require some knowledge of the aircraft, or at least a list of where the circuit breaker identifier lines were to get at them and one would have to know how to do that. that's a very troubling thing that there was this delay. it would tell me that somebody was at, turning this equipment off, and the data link can only be turned off by either a maintenance function or a circuit breaker. there's no switch to it. unlike the transponder which does have a knob that can be put into the standby mode which will effectively turn the transponder off. >> and given your experience -- >> it's definitely troubling. >> okay. and given your experience with this type of plane and this

region, give me an idea, you know, how complicated it might be for someone who is not a regular pilot of this plane to be able to suddenly take over this plane, and be able to make that left as we've seen in the maps and go to airspace over the indian ocean? >> well, access to the cockpit is really the key factor here. or somebody already in the cockpit, like an operating crew member, would be able to do this. now, the shortness of the signoff would also explain the inability for malaysia to be able to identify the individual's voice, even if there were other company employees that would be familiar with the individual's voice. a short clip like that may not be enough time, because there is a little difference in resonance over radio versus your personal voice ear to ear. so it may have purposely been a

short signoff just to quell air traffic control's, you know, query as to whether they got the frequency change to ho chi minh center. so -- there's definitely something afoot. now, access to the cockpit that could have happened if the flight attendants had opened the door to deliver meals. one of the crew members had gotten up to go to the bathroom. just reached cruise altitude. that would be a place where either food or bathroom relief was -- was going on. so the cockpit door may have been breachable at that point. >> okay. take a pause there and every stick around. i want everyone's points of view on this, because this is incredibly fascinating. we're going to take a short break now and continue or conversation about the newest investigation involving this missing aircraft. it's a stationery and gifts store. anything we purchase for the paper cottage goes on our ink card. so you can manage your business expenses and access them online

worsening prostate symptoms, decreased sperm count, ankle, feet or body swelling, enlarged or painful breasts, problems breathing while sleeping and blood clots in the legs. common side effects include skin redness or irritation where applied, increased red blood cell count, headache, diarrhea, vomiting, and increase in psa. ask your doctor about axiron.

welcome back. we're talking about the latest developments in the search for malaysia flight 370. malaysian authorities now saying that they believe the communication system on that plane was disabled and then they heard a voice saying, all right, good night. we're trying to understand what all that marines. we' means. talking with a pilot, pilot and aviation attorney and an aviation lawyer and pilot. welcome back, gentlemen. so mr. savage, before the break you were talking about the fact

that this, all right, good night is a very short correspondence and because of that it might be difficult to try to identify that voice, and so i want to ask you, arthur, if you believe t t that -- that might have been intentional, that it's difficult to discern, whether that is indeed the pilot's voice, or might it be sort of a hijacked call kind of code for, we're in trouble in that region? >> yeah. i think at this point, that's an excellent question, and that's another piece of the puzzle that we have to solve. first off, i think the easiest way to determine if that was the captain or the copilot's voice would be to have a family member listen to it. yes, i agree with bill that voices do sound a little bit different when you're on the air, but i would think that a loved one would be able to discern whether that was her husband, boyfriend, or what have you. but in trying to delineate

whether it was the captain or the copilot, there's another way to look at this, and --with this game-changing information, what we actually have been able to do is narrow the scope down to 239 possibilities. that was the number of souls onboard. before this piece of informat n information, the possibilities were infinite. now we know, because this was an intentional act, the transponder acars turned off. we have a communication. we have a plane which immediately made, or shortly thereafter, made a turn going into a south westerly direction. one of those people onboard is responsible nofor that and that a huge through could lead us to where this plane ended up. >> we have investigations, an accident and criminal investigation now that malaysian authorities have said nearly

definitively they think this was deliberate action. so what do want to see next in this investigation, the direction? what are some of the blanks that you need filled at this point, besides the fact that everyone would love for this plane to be located, but based on the inferring we have thus far, what are the next set of questions that you have? >> well i think one of the biggest questions for me, in addition to your point about finding the airplane, which i think is really critical is that, we have to take a -- everything that comes out of malaysia way grain of salt, at this point, because we have been on so many wild goose chases in the last week. now, whether they were intentional or not, i have no idea. i'm just saying that as a journalist, as a pilot, i mean, this topic of, you know, picking apart the last few words -- to those of us that fly. i spent ten years as a controller. i mean, it's very common on a night shift when things are very

quiet and people are just very relaxed to tell an airplane, hey, contact the center 1-3-9. good night. see ya. or, bye-bye. so, again, are we going to find out that that is absolutely related to something? maybe. maybe not. but we're taking bits and pieces of this story, out of the context of the begin, the middle and the end, and we're all guessing and, again, i go back to the fact that we're basing most of this on the malaysian input, and i have come to not trust that in the last week. >> okay. bill savage. rob mark. brian alexander. arthur rosenberg. you're all going to stick around as far as i know except maybe arthur you have somewhere to go. thanks so much. we're going to take a short break and continue this conversation right after this break.

this voice that's been my father's voice is also now nigh coach's voice during parts of the day. >> after the trap, get out of there and find your man. >> how often do you call him dad? >> very rare. i call him dad. so he's in my phone as coach >> at home he has to back to being dad. it's not all hoops. why? because mom said so. >> at end of the day, we both want what's best for doug. >> now as hi enter the ncaa tournament, once in a lifetime opportunity is coming to an end. >> we look at each practice and each game, the clock is ticking. we're trying to cherish it more. >> not many look back on our life and say we spent too much time with our parents. a lot of us would like to go back and spend more time and doug saw it as an opportunity to spend another year with the family. >> since doug did pass up

millions in coming back for his senior season and you're footing the bill, any reimbursement plan? >> he says he calls me coach mac unless he's asking for a few bucks. i'll probably send him a bill at some point in time. >> if you really want to go out on a limb, you can test your bracket skills against mine in the official ncaa march madness bracket challenge game. i laugh, you know why. go to cnn.com/bracket and join the group to see if you can pick the bracket better than me. we'll be right back. this is the quicksilver cash back card from capital one. it's not the "juggle a bunch of rotating categories" card.

it's been a fascinating day about the latest developments in the search for the malaysian airline flight 370. the prime minister says the cockpit's sign off to ground control, all right, good night was said after the communication systems were disabled. i want to get final thoughts from our panel. they have been so fantastic. so given all that we have heard, gentlemen, tell me what does your gut tell you about what happened to this plane in 20 seconds or less each. brian, you first. >> obviously there's still many possible explanations that are out there. obviously, it's trending towards more deliberate actions, trending towards possibilities

in the docockpit involving the crew. i would point out one thing that's of interest to me in the last 20 minutes of dialogue is the timing of this call and the transponder being turned off. one of the things that's not been discussed is when the transponders turned off, the air traffic controllers at that moment would have lost all the information about the aircraft. altitude, air speed, if that happened before the handoff between malaysian air space and vietnamese air space, that should have send up a red flag to the controllers that something was wrong. you didn't need to wait for the controllers to hear from the aircraft. so that's another factor probably to look at. the other thing is the story needs to shift away from what lawyers and other speculators want to say and really focus on why there isn't more information coming from the investigation authorities. i think that's a good spin. >> rob, 20 seconds or less, what does your gut say about what happened here? >> i like that last comment

about the data block and the fact that the information disappeared. we should have heard the malaysian controllers or vietnamese controllers say something on the radio. i haven't heard anything about that. >> bill savage? >> i agree with the other two gentlemen. it was exactly my thought during the break. but it's quite obvious that whoever was flying that airplane was an aviator and knew how to fly that aircraft. with all of the turns and climbs and decents, plus the interruption of the systems, i speculate that someone knew something about flying airplanes and particularly that airplane whether it was the crew or one of the 239 or more is something that should be looked into. who was in the back of that airplane. >> it's the greatest aviation mystery that anyone can recall. thank you, gentlemen. we appreciate your insight.

that's going to do it for me. thank you for being with us this afternoon. much more coming up of the mystery of flight 370 in new york after this. [ male announcer ] this is the cat that drank the milk... [ meows ]

it's a place named one america's most veteran friendly employers. next is information and entertainment in ways you never thought possible. welcome to what's next. comcastnbcuniversal. i'm jim sciutto in new york. nothing more definite has come out of the search for that malaysian airlines jet, but we have for you is a new focus on a few possibles based on the best information we have right now. and much of that information is new. let's go to it right away. first, a new timeline of events. american, british and malaysian experts working separately all now agree that somebody on that plane switched off the critical communication system while it

was still over land. that's a vital piece of information because a very calm and normal-sounding handoff message was sent from the plane after that point, after the tracking system was turned off. extremely mysterious. back to the ground for a minute. police went through the homes today of the pilot and co-pilot. they are looking hard at the passenger manifest and very hard at the flight crew. little else to go on, officials are trying to learn all they can about the people on that plane. back in the air, if that plane kept flying, it had enough fuel to reach anywhere in western china or asia. some ocht groups in that part of the world have very big problems with china and with the west. and quite possibly the political reasons to justify stealing an airplane filled with innocent people as remarkable as that sounds. i want to bring you to that region a bit to explain the

dynamics on the map here. first, we're going to look at the ark. this is the new ark of the search area, which is incredibly lar large. but it's important to describe what is in that ark to get a sense if someone was trying to take this plane somewhere, where might they want to taken take it. a huge range, it could get to india. india has a civil aviation industry there. it also has a mature and large military with a lot of surveillance that could detect this kind of thing as to many of the nations here. but also this ark brings this northern part of asia into range where the aircraft could have gone. as you get up here, you have the central asian countries of afghanistan, kazakhstan and an area just north of the tibeten area. part of china since 1949. this is where a population lives

of a central asian population that are muslim. there are groups there fighting for independence from china and have used violence in the past. there's no definitive evidence that any of those groups are involved in this attack, but we know know that investigators have been look ing ing to see i there's people of weeger nationality on the plane. it's a possible lead. it broadens the area of potential actors. now that we know the flight range after this plane disappeared includes this region today. it's an area of inquiry. as we get into that, i want to bring in some of our experts who know so much about flying. we have arthur rosenburg, bob bare. arthur, i want to start with you. you're a pilot, you're an engineer. you know how these planes work. let's focus on that new information today. the sequencing, the first system

shut off before it leaves the peninsula. a few minutes later, transponder turned off, after which or around the point at which you hear a pilot give a calm handover. what's the importance of that sequen sequencing? >> toif look at that sequence of events together with the fact that the plane was airborne for about 45 minutes and then today with the prime minister of malaysia's announce mement for first time, i characterized it as it's a deal break er. it changes everything. it's a game changer. the transponder was turned off. the acre system was turned off. then we have what may or may not be, i think it was, inappropriate communication from someone in the cockpit back to air traffic control, all right, good night. >> inappropriate meaning misleading? >> meaning that it's been suggested that maybe that was a code for the malaysian airlines

let i letting people on the ground know that something was wrong. it's possible. typically you'd get malaysia flight 370 and they would repeat the frequency to the handle of controller, which would have been the vietnamese controller. but what happened after that is also telling. you have an airplane after a transponder and system was turned off became largely invisible to the air traffic controllers. then the plane makes a left turn. shortly thereafter and heads back in a southwesterly direction. what does it mean in short? >> it's a deal breaker why? because it gives greater evidence this plane was commandeered? >> exactly. and prior to this, there was uncertain. ty whether this plane had been commandeered, whether it had been hijacked, we had a lot of scenarios. but i think this make s it absolutely clear whoever said that on the air knew that the

transponders had been turned off, the acre system had been turned off and they wanted to become invisible. and they did. >> i want to go to bob bare now. your experience in intelligence, how important is this information and does it convince you that the plane was commandeered? >> i think at this point turning off all the systems, the change in direction, i have been listening to the pilots. i'm not a pilot myself. i think the evidence is myself. the melees have come out and admitted it a week later. the question is, why steal an airplane like this? was it intended to be flown and crashed into an american base? nobody knows that. the second question is could you hide one of these airplanes? i'm not a pilot, but i can tell you in the '90s, i used to fly in a c141. we used to fly into central asia, through the mountains, it

was fantastic flight to avoid russian radar at the time. the air force can get into these places and disappear an airplane very quickly. i can't believe a terrorist group would, but what do i know? >> i want to get to issues about the handoff because it raises questions about how easily a plane could have avoided militaries that have radar there. but bob, let's talk about the groups in western china and the caveat we don't know they are involved, but what do we know about the capabilities of groups, for instance, weeger separatist groups. they have been blamed for a car bombing last fall. a knifing attack just a couple weeks ago. do they have the capability to do something as bold as stealing an airplane? >> they have the motivation to do it. the chinese are cracking down on them hard. they are tearing down their cities. i could see them coming after the chinese.

the problem is i have never seen them turn to aviation before. they are not very sophisticated. they would need to contact a group from malaysia. themselves alone, i doubt it. >> early on i was asking officials in washington whether they had these capabilities. arthur, before we finish just on this point of the handoff, when that plane gave that good night, a handshake, in effect, why didn't the vietnamese authorities alert someone when the plane didn't show up on their radar screens? >> standard protocol would absolutely be that the controller who was second in the sequence, who received the football, who received the handoff would expect within a short period of time for the new frequencies to have been dialled in in the airplane and then the flight crew to make contact with the new controller. the fact that it wasn't here is

telling. it immediately tells the downstream controller, hey, where the hell is the airplane? should they have gotten on the horn and tried to communicate with the airplane, called up the malaysia controller, at this point, i'm unaware whether those commu communications actually did take place, so i would characterize that as pieces of the puzzle which have yet to be defined. >> and that's a fair point. we have seen many of these pieces come in. they have dribbled in often too slowly from the malaysian side. bob, i wonder if i could come to you for one more thought as we get here. early on when the possibility was raised that this plane could have been commandeered somewhere for a later use, that was seen as a far out there possibility, but no one was taken it seriously. something you take more seriously now? >> absolutely. the fact they haven't found the wreckage so far, it could have gone down in a great number of

place, but they haven't found it. the fact that it was so organized makes me wonder if these people have certain capability. i think they were heading somewhere with this thing. did it fail? that's most likely the chances of them actually stealing an airplane and hiding it, i would expect a government to be able to do that, but not a terrorist group. it's still way down the list for me. >> this is a remarkable possibility now even as the evidence has come together. thanks very much. we'll be getting to the issues as we continue tonight. as we just discussed, all right, good night, were the last words radioed from the cockpit. ahead, hear how those words are connect to what one expert says is the biggest breakthrough we have had so far in this investigation. as a business owner, i'm constantly putting out fires. so i deserve a small business credit card with amazing rewards. with the spark cash card from capital one, i get 2% cash back on every purchase, every day.

welcome back. i'm jim sciutto in new york. did something sinister happen in the cockpit of flight 370? we have exclusive new reporting. cnn just learned that the last radio transmission and the words "all right, good night" were said after the tracking system were turned off. joining me is richard quest, who knows flying better than anybody in the building. >> this is really interesting. what's happening here is all i've done is take the prime minister's statement and i've compared it to events that we already knew about that happened. so if you put them all together, you end up with the following. the prime minister saying that the acres was switched off. >> the system that sends data from the plane. >> the information. so this point, it's disabled. at this point, both the

transponder is switched off and we also get the "all right, good night." >> seemingly everything is fine. >> it doesn't matter which you take it. although if it was the transponder off first, they might have questioned it. but what it does tell us is that at that moment whatever was happening was happening and there's no indication on the "all right, good night" that there's something wrong. >> let me ask you a question. this presents some possibilities. it presents the possibility that the pilot did it, either willingly or under duress. or someone else got in the cockpit. >> air traffic control wouldn't know what he sounded like. >> maybe the first time he heard from him. but let's see, you do all these things quite calmly, i imagine under -- you would need to have

knowledge to do it whether or not you were the pilot or someone else who didn't belong in the docockpit. >> which is the extraordinary thing about all of this because the timeline -- let's put it this way. let's say it's the pilot and it's a mechanical or something seriously wrong with the aircraft. but they don't know about it yet. it's not feasible. >> it's not feasible to say they didn't know it stopped working and continued flying? >> chirp like a bird if it failed. but assuming that it is possible, although pilot people say really you'd know. but let's assume it is. as these things tonight, it would be the pilot who would be saying "all right, good night" without knowledge of what was about to happen. if it's somebody else involved, you have to have a knowledge of how to disable acres. it's an electronic thing at the back. you have a couple software pages

to deal with. it's not like turning off the transponder. >> a couple questions here. how easy is it? let's say it was under duress. this is speculation. we're get iting pieces to the puzzle. we're like police investigators pulling this together. if it was under duress, it would have been easy to send one of the sly i'm being hijacked signals because they make it easy in the cockpit to send that signal, is that right? >> i'm not going to give the number out. turn the transponder to the emergency frequency. jim, if they disabled the system, then they certainly knew what they were doing about transponders from anybody who has read a tom clancy novel. what i think is very crucial here is not to jump to -- as you have been saying all week s to accept what we know and work out

from there. and what we know is the system was disabled, transponder disabled, waiting for more confirmation on the "all right, good night." was it simple where it would be improper because it should be malaysia 370, the instruction. >> interesting. does that give a clue at all in that it was so simple that it didn't give an identifier? >> you would have been told contact vietnam control. and then he would have said, contact one, vietnam control, malaysia, all right, good night. but we don't know whether the officer who revealed "all right, good night" just didn't tell us the precedence. but before anybody jumps on me on all of this, it's bursting with pilots who are pointing

the -- the information may be lacking is about procedures and methods and means is being provided and is being assisted by an entire body of people out there who are helping us understand. >> thanks very much. we'll have richard back in the broadcast. just to be clear, we're making baby steps forward. this is a step forward. it doesn't eliminate any explanation, but it does give more evidence for the planner, even as the prime minister said being under control at that point by someone under duress or in control of the plane. thank you. we'll have you back. coming up, he's a best-selling author, host of "decoded" and was hired to help prevent terrorist attacks. we talk about why this disappearance has captivated the world.

welcome back. i'm jim sciutto in new york. everyone wants to know what happened to malaysian airlines flight 370 and with so little hard evidence to go by, everyone, it seems, has a theory. brad is author of "history decoded." thank you for coming on. you are a student of history. looking at this, i'm just curio curious, when we look back through history involving flight, is there any precedent for this kind of thing where a plane just disappears. we don't know what happened to it, but there's talk of it being commandeer commandeered. any precedent for that? >> it's interesting. when you look at it, forget about the flight part. it's amazing to watch historically how times have changed. when abraham lincoln was killed,

it took a month for some people to know the president died. jfk was hour. and boston bombing, you see how quickly information moves. that's what's the most fascinating part to me. you're seeing almost the investigation happening realtime. everyone gets to see it happen in realtime. that's kind of the unprecedented part here. i got a call that the best investigator i know in private security, i knew something was up when she called me two days ago and says watch what's going to happen. you can feel the american people feel that something just smelled wrong here. >> no question. every day there are more signs that something went wrong here. maybe something nefarious. you talk about technology. certainly the information moves more quickly, but would you have a false sense of security that we have a false technology that

would make something like this impossible. so many systems on the plane, satellites watching, radars watching, the idea this thing could disappear, it seems incredible. >> of course. that's what always is at the heart of conspiracy theer ris. two things. one, it's just the facts that seem wrong. and one of the first ones before we had any information was the simple detail that in this nsa tracking world that no one had a cell phone that was on and people are saying when you call a cell phone on a plane it should go to voice mail, but family members said the phone was still ringing. and suddenly people start going, wait a minute, that can't be right. anyone on a plane knows there has to be one person on the plane whose phone is on and doesn't listen to the rules. you're telling me all of them are gone? people go what's happening? the real root of where the conspiracies take place is they come from our deepest fears. to me that's what we have to focus on here.

we are watching the plot of "lost" play out in front of our eyes. the only thing mising is the magical island. and the american people look at that and combine that with the great fear of plane crashes on a regular basis and some you have the makings of what you see here, which is, of course, everyone reacting. we all know this is not a normal news story. there's something bigger and something people smelled a mile away. >> it's incredible when you think that one of the early conspiracy theories on the flight was that it was taken somewhere and the passengers were still alive. six days ago that seemed a fantasy. now there seems to be some evidence that's at least possib possible, far pr confirm the, but at least possible. here's a case where the conspiracy theory moves into the realm of the possible. >> that's always the fascinating part. some would have been two young nutballs until they are right. and then when they are right,

it's a different game. it's the same thing here. on thursday every network was saying the conspiracy theories, those are ridiculous, those are silly. today they are going we need to investigate where the plane is, where the security tape is of the people that got on the plane, how anyone on that plane -- what did they know, who could fly a plane, who knew how to use the different systems on that plane and suddenly all those cooky theories are suddenly going into the realm of truth. it makes people realize that conspiracy theories, in a way, are the very original form of crowd sourcing. there's a real power when you bring people together and let them play it out. we saw it in the boston bombings. in a matter of hours after the bombings happen, we have information. atms, people's cell phones, and they say, we have to find these guys. let's turn it over to the american people and they find them. this is what you're seeing here. again, it's that form of crowd sourcing where all this information, all these questions and the demand for answers at

one time are what's providing the story to keep going but to dig for a real truth. >> we should caution our viewers that there are other equally plausible theer ris. for instance, military officials are saying that the plane is on the bottom of the indian ocean now. not proven by any means, but that's plausible too based on what they know. it's early stages here. brad, thank you very much for talking us through some of the many possibilities. come iing up, we take you inside the cockpit of a boeing 57 to possibly talk about some clues. hey guys! sorry we're late. did you run into traffic? no, just had to stop by the house to grab a few things. you stopped by the house? uh-huh. yea. alright, whenever you get your stuff, run upstairs, get cleaned up for dinner. you leave the house in good shape? yea. yea, of course. ♪ [ sportscaster talking on tv ] last-second field go-- yea, sure ya did.
