but the acars data is stored on the acars system and transmitted through the s.a.t. com so it's possible there is a separate way to turn off the acars without disarming s.a.t.come, the way i interpret this data, two different things going on here. the fact that the acars stopped transmitting between 1:07 and 1:37 is not uncommon. but the fact this that it didn't report when it was supposed to concerns me a great deal. what i'm confused about is whether or not and what i don't know is whether the s.a.t. com tried to communicate at 1:37. if it did and no data came through, that's one scenario. if it didn't, then that's something else, meaning the s.a.t. com had been turned off at that point and was turned on again later on seven or eight hours later. >> what so many people agree, it is highly unlikely this is just a big coincidence. david souci, thank you for your insight. john lucic, as well. richard quest, stick around if you will. more questions than answers for pretty much anyone involved in this now mystery. how did both communication systems on board that plane g

at 1:37, half hour later, acars should have said now it's doing this. acars going silent. means it was shut down deliberately or accidentally or transponder went off. if you take this new information essentially it means you had an aircraft reported in normal and then sometime immediately after that the transponder and acars system stopped functioning and appears there was a turn on radar. is it deliberate all this stuff was shut down? it could still be painted as somebody wanting to hide movements or it could be an accident. back to that, jim. >> other pilots told us a few minutes ago there's another way to turn the plane tlibtly but still under control, not under control of pilot on the yoke but turning the heading in which case the computer would still be flying the plane, autopilot under control and hit those way opponents we talked about perfectly. could you show us how that would work? >> go ahead, tell us. >> the autopilot is controlled through this panel. we call this the remote control panel. all it is, the number you see here is heading. degree magnetic this is c

acars never transmitted again. it's a different scenario, we're back to looking at catastrophic failure. the one problem with that, anderson, how does a plane that has a catastrophic failure go on to fly seven more hours? there's also a window for the hijack theory but a very narrow one. this is going to be something debated all day today and well into the future. anderson. >> jim, thanks very much. and it could be mechanical failure, not something catastrophic, not suddenly ingt u.s. as the plane did continue to fly. it could be something pilots were battling. we've got experts in every aspect of this. david gallo who co-led the search for flight 447, fran townsend is here, former homeland security adviser and 777 captain, les, joining us as well. les, you've been flying for nearly 30 years. as you look at this, given what we know, the transponder was off, as we said, that went off at two minutes after the last communication at 1:19. 1:21 the transponder goes off. we know the 1:37 a.m. acars system that was suppos

bear with me. 1:07, we had that acars reference. 1:37, the next acars message should have been sent from the plane. but it wasn't. so sometime in that period, either it was disabled or it failed. but we know between 1:07 and 1:37, they were the key times. finally, 2:15. we get military radar, last detects the plane. and 8:11, the satellite makes its last so-called handshake. now, wolf, pull all this together. and what we come back to is a very fine line, a very defined area where between 1:07, 1:19, 1:21, 1:37, the incident was taking place, wolf. >> so this -- these are critical moments, as you correctly point out. two systems stopped working during that same rough period, the handover, between the malaysian and vietnamese air space, that handover was taking place. so would that be an optimal time for someone to do something wrong in this particular place? >> absolutely. and it seems to be -- i mean, the conspiracy theorists say that is exactly the point upon which you would do it. let's go back if we can to the previous page on this time line. keep -- here we are, exactly the page. so

his acars turned off. transponder turned off. i'm looking at the pilot. >> thank you very much, a short break and continue this conversation. much more on these new details involving this mysterious disappearance of this airplane. humans -- we are beautifully imperfect creatures, living in an imperfect world. that's why liberty mutual insurance has your back, offering exclusive products like optional better car replacement, where, if your car is totaled, we give you the money to buy one a model year newer. call... and ask an insurance expert about all our benefits today, like our 24/7 support and service, because at liberty mutual insurance, we believe our customers do their best out there in the world, so we do everything we can to be there for them when they need us. plus, you could save hundreds when you switch -- up to $423. call... today. liberty mutual insurance. responsibility. what's your policy? it took a lot of juggling to keep it all together.k. for some low-income families, having broadband internet is a faraway dream

the acars had been shut down. the final call had been made by the crew and the transponder shut off. and that was really served as the basis for a lot of the suspicions that someone on board was responsible for deliberately steering this aircraft very significantly off course. >> right. >> at this point what we have is almost a 180-degree reversal saying that the government expected that the last acars message was going to come a bit before it came and then the one they expected later never came, so we don't actually know or why the malaiysian government believes the acars system was shut down. >> riechght. so the idea that someone in the cockpit, the pilot, the co-pilot or somebody else turned off the acars and then said "all right, good night" is a fallacy because it didn't send a beep 30 minutes later like it was supposed to. it could have stopped working because the plane had crashed, right? >> well, there are a lot of different possibilities about what could have gone on. certainly we've seen anything from th

acars does not translate anything having to do with gps. acars only gives specific information and that's information about the health of the plane. these pilots that i spoke to who are very familiar with the 777 say they don't know any way in which that particular system could let anyone know whether someone preprogrammed that turn into the original flight path or the itinerary, so to speak. whether they are basing it on acars, whether they are basing it on data from radar, that's unclear. different people have different sources. but here's why any of this really matters. because you may be watching at home and you may say, okay, this is an incremental change here but it matters because if somebody did indeed preprogram something or that flight plan into the flight management system a long time ago, then that would show essentially that someone was premeditated. this was a premeditated action. if it happened moments before the turn, then that would simply show that it was an emergency or perhaps there was an intruder. jake? >> very importa

acars is transmitting normally at 1:07 a.m. at 1:19, the final words from the co-pilot "all right, good night" were received by air traffic control. >> can you tell us what you were doing inside the house? >> reporter: that led investigators believe that both acars and the plane's other main transponder were purposefully turned off and focused suspicion on the pilots. >> these movements are consistent with deliberate action by someone on the plane. >> reporter: but monday, the ceo of malaysian airlines told us flight 370's acar systems might have been functioning and weren't supposed to transmit data until 1:37, well after the pilots reported everything okay. >> the last acars transmission was 1:07, okay? we don't know when the acars was switched off after that. it was supposed to transmit 30 minutes from there, another transmission, but that transmission did not come true. >> reporter: what does that mean? john, that means that we don't know if the pilots really switched any of that off. they may have suffered some kind of mec

the acars system -- what your reporting does is establishing the acars system must have been functioningrokes were put in. obviously we wouldn't know about them otherwise. anything there your sources about who would have the know how -- >> that's close. >> go ahead and qualify for me. >> that's close. not necessarily when the key strokes were put in. the key strokes could have been put in while still at the gate, put in during climbout. however, at some point either because the airplane had made the turn or about to make the turn, this was the current instruction or next instruction. then it was radioed back. it depends on how this was set up. it's not completely clear how acars was set up to inform the maintenance on the ground. this is maintenance not air traffic control. inform the maintenance on the ground what's going on in the airplane. >> that's interesting. they know it was put in but don't know when necessarily. another answer that gives us a couple more questions which is the way this has been progressing any way. matthew, appreciate you coming in and telling the us what the re

the so whoever is disabling an acars system, it's a long process. for someone who knows what they're doing, it can be done, but it's not a simple three position that you'll be turning off and on. >> exactly. so the fact that this plane stopped -- martin, the fact that this plane stopped transmitting acars' data in a series way is significant in that respect bearing in mind what you're now seeing in the cockpit? >> i want to there will be quite a bit of information there ak sellerometer. to help conduct that investigation. >> oftentimes, the most simple answer here is probably what's happened. and we've heard the payne stewart question come up again and again. was it a depressurization. i think it's simpler than that. it may have been something more likely just a minor cockpit fire where the smoke overwhelmed the crew but not before the captain thought i'm going to turn the airplane back towards land, towards the last known point. he be that intense they wouldn't have the time to put on simple oxygen masks to at least signal a distress call? >> it co

acars on steroids, actually.ecause we've had acars on domestic airplanes and they don't have the reach, radio reach. so the technology has been moving forward to make sure that we can keep track of our airplanes. because it's less expensive to have the airplane tell you where it is than it is you try to build radar stations all around the world to spot the airplane. >> i want to ask you one other question which may be a dumb question, but it's on a lot of people's minds i know because people have been asking me about it all day long. people are asking, you can find a cell phone. you can track down a cell phone through satellites these days. would it be possible to do that on any of the passengers' cell phones to somehow get a gps location from any of the passengers' cell phones if they're out there? >> no. what's wrong with that you're not getting the signals from the satellite. the cell phone's getting the signals from towers. in this case the towers can be equated to a radar tower as well. and you need multiple

we still don't know the circumstances of why that acars system or how that acars system was shut downand that's very important. true. but even thousand i might be a little bit more intimate with the systems on the airplane, this is not an intimate part of my knowledge. >> as a pilot -- >> this is nothing a place that i view. a friend of mine after being on the airplane for four years and now retired said he's never been down there. >> is that right? >> because there's no real need for us to be down there. there's one circumstance that i would go down there and that's simply after a inciden incidents a diagram on where to pull a particular circuit breaker like what's being pointed out here. >> if there was a fire on board or smoke, is that part of the procedure to turn circuit breakers off? turn off the in flight system, to turn off the acars? >> it wouldn't be to go down those steps to do it. it would be something that's done in the cockpit. we have circuit breakers in the overhead panel that might help perform that. most of that are switches as opposed to circuit breakers. that would

programmed before acars went down and executed only after the last radio call and after the transponders went dead. if the pilot entered that turn, why? >> some pilots will program in an alternate flight plan in the event of an emergency. we don't know what the reason was for this particular flight plan, whether to go back to kuala lumpur or take the airplane somewhere away from beijing. >> coming up. >> flight deck flight simulator in anaheim, this retired american captain helped recreate in a 737 what we know. someone turned off the transponder with the flip of a switch. >> you can see i can press the button, acars and that would bring it up. >> they switched off, then disabled the acars data system possibly by pulling the circuit breaker. >> circuit breaker would be on one of these back panels behind the pilots. >> easy steps for a pilot. total time, 20 seconds. then making a u-turn back to kuala lumpur. >> we want to go back to kuala lumpur which is behind us so all i have to do is spin this knob for the heading around and the aircraft will turn around. >> sources tell nbc news whoev

it transmitted its last automatic data burst, called acars. the next acars transmission was scheduled for 30 minutes later. it never came. 1:19 a.m. the copilot radioed "all right, good night" as malaysian air traffic controllers handed the plane over to vietnamese controllers. just two minutes after the very standard conversation, 1:21 a.m., someone in the cockpit turned off the transponders that send speed, location, altitude and heading information. soon after that the plane turned around. at 2:15 a.m., the last radar contact in the strait of malaga, headed north. over the next six hours the plane transmitted one ping per hour to an orbiting satellite until 8:11 a.m. when the last ping was received. that puts it somewhere along these two arcs. as far north as kazakhstan. as far south as the deep indian ocean. australia is now taking over that search zone. >> we will do our duty to the families of the 230 people on that aircraft who are still absolutely devastated. >> reporter: experts say turning off acars and the transponders, then flying

that's what the acars system does in part. they use it to communicate to the home office if they had the data plan. the data we could have gotten is missed because they didn't have the data plan. >> it is a shame we don't have it now. john lucich, thanks so much for being with us. >>> we'll get back to our top story in just a moment. >>> just minutes ago, president announced sanctions against key figures. he has been clear that neither the u.s. or many others recognize crimea's referendum vote that was held sunday to leave ukraine and join russia. his announcement goes after top players in russia. >> i have signed a new executive order that expands thescopies of our saenctions. as an initial step, i am authorizing sanctions on those that work in the arms section and provide material support to senior officials of the russian government. if russia continues to interfere, we stand ready to impose further sanctions. >> vladmir putin still needs to approve that annexation. president obama's announcement comes in addition to the eu

that's what i'm referring to when i say ping from the acars system.ause it has to communicate, send that ping out and get the reinformation back. so let's assume there really were pings coming from that location. now assuming that, i find it extremely difficult to think that somehow the system failed, that 777 is the most reliable aircraft in the air in my opinion. and to think that that whole system, the three buses that we have, the three generators, the backup generator which can be driven by air, that can power those avionics and those communication channels as well. so i believe that it was taken off by intent, that that aircraft was intentfully disabled from communication and that it has been flying. it makes sense to me that the pings are still occurring for one reason. if you're going to -- the average pilot would know how to disconnect all the communications equipment on that airplane except for one thing and that's the acars system. because there's a circuit breaker. when you pull the circuit breaker that says acars on it, it doesn't turn of

acars sends the pilots the route. they sit at the gate, they confirm it, it's usually completely on point. for them to change it at the gate, they would have had to both be in on it. if they changed it in the sky, one pilot could have, you know, been pressed. >> gone to the men's room. >> gone to the men's room, like the egypt flight in 1999. it makes you think it has to be one of three things. either if it's a hijacking situation, the hijacker did not know enough to tell them to turn the transponder off, right? and maybe the pilots left it on, hopefully to stay in contact. or they left it on or they were sloppy, if these pilots were the ones hijacking, maybe they forgot and left the transponder on. >> we talked this week about if it was terrorism, there's been no claim of responsibility. remember, in a lead-up, in the planning to the attacks on 9/11, they didn't preclaim responsibility if they were planning something bigger later, which is why i think that our homeland security and intelligence officials are right to

acars transmission at 1:07.s switched off after that. >> in a normal flight acars should have transmitted information about how the plane was flying, engine data, fuel burn and any maintenance discrepancies, pilots say it's abnormal to voluntarily shut acars off. and we also learned today from malaysian authorities, they have not found any evidence from any telephone company that anyone on board was trying to call or text out, but they say they're still checking into those phone records. there are millions of them. >> a lot of people are looking for those, too. rene, stand by. i want to bring in peter bergen, our cnn aviation analyst and the former ntsb managing director, jim sciutto is with us and richard quest from new york. that report at the top of the hour we heard from nic robertson where out of a measure of prudence the israelis are beefing up their air defense system worried potentially that maybe this airliner is on the ground someplace, could be refueled and flown towards israel as sort of a missile. h

received at 21:37 from acars? >> correct. that's my understanding. >> it's likely that it happened and 1:19 is when the co-pilots said good night. >> just your point, the u.s. the malaysians weren't transparent in the first week and came out saturday and sort of publicly came out and said this was foul play. now the stuff we are getting is being passed to the americans and now to us. and it's very hard to know whether the malaysians have a good handle what's going on. >> interesting because the plane was due to land at 7 a.m. but you would think that if at 1:07 was the last acars communication. they expected another one at 1:37. they didn't get it at 1:37. did they look at the plane or think about where is our between 1:37 and 6:30 plane landing at beijing or ignore it? >> that's the thing it doesn't look like the malaysian military did anything about it. >> how about malaysian shah airlines? weren't they missing their plane. >> there are all these questions. i get asked this all day. where is the plane what happe

so acars is doing its normal job, they have normal communication, they have normal acars reporting, and then a line is drawn and things change drastically. we have to look at what things could cause the pilot, for instance, to turn back. and a pilot would turn back if he -- his plane is in trouble. and that's why he wouldn't descend and land. there are other issues. every theory as holes in it. we don't have enough information to make a complete picture. but the fact that akors and prepamming of the flight management system didn't occur prior to this line being drawn leaves open the option that the pilot was simply dealing with a very difficult problem, and although not a zero probability that he would communicate first, controlling the plane and getting the plane where he wants it to go could easily be the first priority if there was something like fire or smoke involved, he could put on an oxygen mask. sounds like a simple thing, but it complicates both flying the plane and communicating. so if it was electrical, then all the things at once could be electrically based. typically when

acars is off, and then it was manually put in the computer, a new flight path.d then we have a sense of direction based on the hours it was in the air, and the pinging came up. is that a good summation of why you believe that? >> yes, and the distance from kuala lumpur, to beijing, from kuala lumpur to lahore, pakistan, the fuel that they have makes it very plausible. the other thing i think it is important to say. the pilot and co-pilot is two very devout muslims. it is against their religion to commit suicide which is the strategy of going out into the south indian ocean and just crashing the airplane. that doesn't make sense to me, they can kill themselves if they're a martyr, a shahid, that has not been declared. i have heard no logic why the planes would have gone into the south indian ocean. >> and going back to the pilot. we have analyzed the t-shirt he had, democracy is dead, his support of the opposition leader, anwar ibrahim. that all factors into your thinking. but the other thing is you have people you're talking to, sources you don't want to reveal.

let's go with the assumption the acars was turned off.nmarsat needs to still know it's alive and well. because if it gets an incoming, it needs to know that it's on so it can push a signal there. otherwise, the inmarsat, if you imagine how many acars receivers it's looking at on aircraft all over the world t can't monitor every one, so it has to know which are turned off and on. so as richard was saying, it establishes this handshake. what inmarsat haven't done in the past, they haven't by norm located that handshake, because you have transponders and this other equipment. this is an unusual case. so i think what they have done is gone back to inmarsat and said look, we're in a sticky situation here. is there any way at all we can try and locate something to do with that ping. and so i think it's -- i don't want to oversimplify it. but if you look at the speed equals distance over time, distance equals speed time, time. they might have gone back and said right, let's look at the time the interrogation signal was sent out, the time we got

on flight 370, the acars system has been disabled. >> to disable the acars system tharks is not easy. who fly for 30 years are stumped on how they would disable the acar system. >> the evidence right now leads us to believe it was an intentional act. the question is, by who? we were there. your first roll, your first friend, we were there too. and swaddlers blanket-like softness, that you've loved since day one, is now available through size 5, for many more firsts to come. ♪ wishing you love, sleep & play. pampers. >>> eight days after malaysia air flight 370 disappears there's still no details of the plane. after suspicious details, the search also turns into a criminal investigation. >> we learned that the plane made a turn and might be going back to malaysia, what's the significance of that? >> when you first look at that turn, you have to think, well, okay, was the turn back because they were experiencing some sort of abnormal or emergency situation that required a return back to origin? but now you couple that with the intentionally disabled of the transponders, that's not a nor

but even after acars is turned off, acars sends what are called handshake signals to satellites.hat some of these signals were detected by satellite, and from that we've been able to calculate the distance from the satellite that the plane may have been. and that's what led to that map that you were showing earlier. >> and share what you discovered about passenger cell phones. a lot of them are equipped with gps system. they have those chips. one would think that maybe that might help in the search. >> well, that's a really great question. you know, what gps chips do on cell phones they're a lot unlike what you might find in a car, for example. you know, what cell phones have are called assisted gps which typically relies on, you know, connection with the cell tower and a data connection in order to get a more precise fix. now, without data connection or connection to a cell tower your gps chip in your phone is not going to be as functional as it would be on the ground. >> okay. and the radar, the fact that radar is not as effective, i mean, it's because if you're going to be out

yesterday, malaysian airlines clarified that we cannot determine exactly what acars has been disabledrred within a specific time range from 1:07, approximately when the aircraft reached the east coast of peninsula malaysia and the last acars transmission occurred to 1:37, which was the next scheduled reporting time. this is indeed the case. it does not change our belief as stated that up until the point at which it left military primary radar coverage, the aircraft's movements were consistent with deliberate action by someone on the plane. that remains the position of the investigating team. it is also important to recognize that the precise time acars was disabled has no bearing on the search-and-rescue operation. we know that the last known position of the plane as confirmed by the international investigation teams was in either the northern or the southern corridor, which is where our search-and-rescue efforts are focused. our priority has always been to find the aircraft. i am aware there is also a lot of interest in the royal malaysian police investigation into the passengers and

the window beginning with the last acars transmission. what jumps out at you? are. >> how accurate is the information? it seems to be changing day to day. if you assume the timeline is accurate for purposes of the discussion, it tends to suggest a more deliberate shutting off of the systems. i still think you cannot rule out the fact that there was a mechanical failure as an explanation for all of this. some of these ways that these machines can fail, the systems can fail are random. >> this can go 8,000 different ways. you heard the theories out there. we are inquisitive on each. let me stay with you. wu know also how much fuel the jet had. given that amount of fuel, it is possible. we don't know the direction of the plane. we have seen this massive ark. it could have gone to kazakhstan if it took the northern route. when you think of all the countries that would have had to travel over through to get there, could it have gone undefected. >> that's the key question. it seems highly improbable unless we have been under estimating the capabilities. to fly at 29,

that is the interface between the jet and the acars. that provides position, altitude heading and speed. the acars was switched off. what we know about is these pings. yesterday we're talking about these handshakes. they come in the form of a microwave. it's all about doppler shift. >> explain this. >> what we can say is if the plane is moving away from the inmarsat satellite, you get this elongated wave. if it's moving toward the satellite, you get this compressed wave. we know the station stands fixed in the orbit over the indian ocean. what this has led the analysts at inmarsat to be able to do -- this is unique -- it's allowed them to look at some of the differences in the wavelength and from that unique information they've been able to correlate it against various other aircraft in the region. let's go to the next map and i'll show you. we have the distance. we always knew about the distance, which gave us this arc, there be a lot of questions and rightly so, why has it gone south, why could it not have gone north? what they've don

acars, flight management system, communicates across to data link when you're near the ground.th natalie when you go over the ocean, those lings fall away and you use the at light system. in this case there's two brands you can use. it happened to be turned off or at least the acar system was turned off so there was only handshaking going across. frankly, i don't really know -- >> would the acar system have been able to transmit that information? >> it would if it were turned on. but if you turn the system off, then really there isn't anything to be sent through the data link. so at that point i don't know how they would know that it was preprogrammed somehow into the a contraction ar system unless they know the data link was still active and there was information going back and forth. >> a quick question. could that computer in the cockpit which adjusts the autopilot, if you will, could that be hacked from the ground? >> it's not very likely. i've certainly talked to many experts who don't think that's likely. there's a lot of precautions against that. if you're going to hack

acars stands for aircraft communications, addressing and reporting system.er on a plane that collects information about what the plane and pilot are doing and sends that information to the ground. we want to talk more about that. lets bring our panel of experts, aviation attorney justin green, senior law enforcement tom fuentes in washington with terrence mccoy. "washington post" reporter who has written extensively about flight 370 and kit darby. thank all of you for joining us. kit, let me start with you on this new information. how much weight should we give it? >> to me, it was confusing. when it first came out it confused my possible theories. i'm glad it's gone. to me it didn't make sense in the beginning. now that it's ruled out things in the normal process, things that normally occurred, it was normal up to the point we lost contact. no one was preplanning something that would be nefarious. >> we were thinking it started to point some of the focus on the pilots, if investigators thought possibly this flight path had been preprogrammed in there. tom f

>> i agree, with the acares turned off, you have the communications piece of the acar system still workingnd essentially on the hour like they said. every hour it is putting its happen hand up saying hey, here i am, putting a radio signal out saying here i am. and the satellite is picking it up but there is nothing behind it because they have already turned off the memory. it is almost like a cell phone in your hand, you have the knowledge in your head, the cell phone makes the connection but you don't talk. >> does that include the mechanical communication via satellite sent out that in fact this is how for example the engines are working at any given moment during a flight? >> yes, now remember, that is a service. you have to pay for it. there is conflicting reports right now that malaysia has not paid for that. they didn't want it. it is on the airplane. it may even actually be working. but if they're not going to pay for the service the service provider is not going to collect it and store it. >> all right, mary, final thoughts. >> it is not clear by all the stories. what the real trag

at 1:07 a.m., the plane's data communication system the acars system, sent out its last automated message, they are programmed to fire off every 30 minutes, what we did not know until moments ago is at that time the plane had already changed course, heading west away from the intended destination of beijing, all without a word from the co pilot to control. he spoke with them at 1:19 said nothing about it. again, this is a full 12 minutes before the person sent out the last calm message. all right, good night. . scott brenner is a former faa senior official now with gephardt government affairs, if this is the case, that in fact at 1:07 a.m., the acars communication system was transmitting data that this plane had already made its turn, is that our information? >> that's what i understand as well, megyn. >> had already made its turn then that would suggest that this co pilot knew a lot more than he was communicating to ground control and places a whole new spotlight on him. >> no, absolutely. this was programmed, in we don't know when it was programmed in, if it was before the flight took o

then you just see what's called the acars system. that's a different system, and the source told me tonight, he, by the way, flies 777s, so he knows, he tells me that in order to turn the acars systems off, that talks to the satellite, you have to go somewhere else besides the cockpit and you have to actually pull a circuit breaker or turn off a third radio, disable that. so you have to know what you're doing. this is much more complicated and indicates somebody with a high level of sophistication. >> let me ask you the other scenario, that there may have been been an additional pilot on board. it's not uncommon for pilots to be able to come into the cockpit and fly in the seat. >> that's right. and it's not uncommon and it's happened before, pilots with distress or financially in arrears have actually crashed the airplane, committed suicide with everyone else on board. so these are a lot of scenarios being looked at. one other piece of information we do know, and i heard this from a source just a few minutes ago, we know that these
