here. don lemon is coming up in just a second but as we leave the air tonight, let's go back to the loved ones staring at their cell phones. just think of the anticipation and the hope for those folks. we've got to keep the story going if not only for them. here's don lemon. this is a cnn special report, the mystery of flight 370. i'm don lemon. the malaysian airlines flight has been missing for 12 days without a trace. no word from any of the 239 people on board. despite a search that now covers nearly the size of the continental united states and that makes the missing plane a worldwide obsession. you know that. thousands of you have been tweeting your questions for days and tonight we've got the world's top experts in aviation and security standing by to answer those questions for you, like is it realistic that a fire incapacitated the pilots but the plane remained operational for

hours? with all the conflicting theories on what happened with the plane, at what point do investigators start eliminating them? and with all of the technology in this world, why is it that planes don't have an unstoppable tracking device attached? we're going to begin with a big development tonight. reports that flight 370's abrupt turn to the left was programmed into the onboard computer at least 12 minutes before the co-pilot's famous final words "all right, good night." cnn's jim sciutto and richard quest are both here. the plane's program was changed at least 12 minutes before. what does that tell you? >> at least 12 minutes before. what it tells me is that when that reprogramming happened,

either by director into the flight management computer and it was executed, probably the ground was informed about the change over the acars system. how do we know this, don? because of the 12 minutes. remember, this is a timeline business. at 1:19 there was the last "all right, good night." go back 12 minutes and we're at 1:07 or earlier and that's when we got the last acars messages. so that, i'm guessing, is how they knew about this reprogramming. if the report is correct. but i want to emphasize. >> all right. >> we need official confirmation about the reprogramming. >> all right. more developing news. i want to get to jim sciutto now. officials reviewed the cockpit conversations today. what did they find? >> well, this is part of the baffling case that this whole story has been from the beginning because on the one hand you're getting more

information that i mplies there was direct information to change the direction of the plane, very suspicious. but as the investigators have looked at the past and present of the cpilot and co-pilots, thy are not seeing anything that indicated a problem. when they looked into their past, they looked in their e-mails, computers, they didn't find contact with extremist groups, signs that they were thinking about suicide, for instance. so on the one hand, while you're building evidence that exonerates them from wrongdoing, you have evidence that they were involved, that it was a deliberate act to turn the plane. you're getting more evidence that that is, in fact, the case. >> as we've been telling you, this show is for you, the viewers. so richard and jim, jim, i'm going to give you this one. many people have been tweeting about the u.s. government's response to the missing plane. this is from sarah and she says, "how is the united states

responding to -- when can the u.s. take over this investigation? i think it's about that time. just saying." jim? >> unfortunately, it's not the way these things go. if the plane crashes on your territory or if it is a flagged plane, in this case, malaysian air carrier that disappears over international waters, it's the responsibility of that country to lead the search for the plane. that's the way it's done. now, many countries, as we know, have offered in fact more than two dozen countries have offered help and they are involved in both the search for the aircraft but also in terms of analyzing satellite and radar data and the u.s. very much involved in that. we've got -- the u.s. has the most advanced aircraft searching the waters, a very new aircraft, a p-8, poseidon searching the waters. certainly ntsb officials are on the ground, the fbi.

it's very involved but it's got to be led by the local authorities. >> stick around because i want to check in with martin savidge. at this moment he's in a 777 flight simulator. martin, we've received questions about whether this plane made it to land. i want you to help out with this. the himilayas are vast, is there a chance it could have crashed there where the radar coverage may be spotty? >> don, we can do that for you in a couple of minutes. that takes some setup. one thing we wanted to show you here, the flight management system. this is the system that you should think of like the gps in your car. this is what brought about the course change, we believe. how easy is it to do it? just a couple of key strokes like your gps in the car.

all you have to do is hit the execute button and within a matter of just a few entries, we begin to make this aircraft deviate and turn off course. it's that simple, don. >> very simple. martin, check back with what we said and we'll check back with you later in the hour to answer marcus' question. all of us are experts here and we dig deeper into the questions that the viewers have been tweeting us. i'm an expert journalist and we have aviation experts on here. many of you have asked whether a fire onboard could explain what we know about flight 370. is there a possibility that it caught fire and radar, et cetera, wasn't manually shut off but an accident? we have cnn's stephanie elam to dig into that question for us. >> you know, what we're given here is a large jigsaw puzzle that has 1,000 pieces and someone tossed 20 pieces at us and said here figure out what

this is supposed to represent. >> reporter: he flew jet lines for 34 years. like many in the aviation community, he has a theory about what happened on flight 370. a problem on board. >> i like to go with the simplest explanation. >> reporter: maybe they were being heroes and trying to get back to a landing strip that was large enough to carry a 777 and that's the reason they made that large, sharp turn. >> if you have a serious problem aboard a jetliner like a fire, one thing you're going to want to do is get on the ground as soon as possible and turning back towards malaysia, towards a large airport, it's the first thing i would do. the most imperative thing is to take care of that fire. the last thing you're going to do is communicate unless you have the time to do it because no one on the ground can help you. >> reporter: so would a crisis like a fire leave the pilots to take drastic action? would it be crazy to think that just going into the water, trying to do a water landing of

some sort -- >> no, i seriously doubt that anyone would try to land a jetliner in the water at night. imagine hitting the water at 100, 200, 300 miles an hour. it's going to make the airplane splatter into pieces. >> reporter: isn't it surprising that we haven't seen any debris anywhere? >> i think there is debris. the ocean is huge. i don't know if all of the ocean has been looked at. i doubt it. my guess is, and it's strictly a guess, that they will find pieces of this airplane soon. >> reporter: the idea that the transponder was turned off deliberately. >> it stopped working because somebody turned it off or perhaps there was a electrical fire or some kind of problem in that airplane that depowered the transponder. we don't know what happened. >> reporter: and because we don't know what happened, he argues the pilots should be given the benefit of the doubt. the idea that their legacy is

being drug through the mud is upsetting to you? >> it's very possible that they were working to do the best they could to combat a very difficult problem and became overcome by fire, perhaps smoke. from everything i've seen about these pilots, they were pretty sharp guys. >> reporter: stephanie elam, cnn, los angeles. >> stephanie, thank you. joining me is jim sciutto and richard quest and mary schiavo. mary now represents victims of negligence by transportation companies, including airlines. jeff beatty and arthur ross senburg. i want to start with this. this is from meredith. she says, is it realistic that a fire incapacitated the pilots but the plane remained operational for hours? jeff, the smoke in the cabin

theory has been a big one today but you don't like that do you, jeff weiss? >> no. the idea that they were incapacitated, turned to the left and looked for a runway, the problem is that they flew past it and then proceeded to engage in a series of very precise maneuvers heading over these waypoints in the sky and followed the zigzag pattern that incapacitated pilot could not have done. the other problem is that if they had just become incapacitated and headed towards lan could you wee and headed into the horizon until their fuel ran out, they would have wound up near the horn of africa or something. they would not have ended up in the south indian ocean. so on two counts at least this theory doesn't hold water. >> here's another one here. this is from fs taylor. the fire theory makes no sense.

why turn off the transponder if a plane is on fire? instinct would be s.o.s. contact passing information. >> i think that possible see is a shrinking one but i'm not willing to fully dismiss it yet. i think it's possible that they made that turn because they were dealing with some sort of emergency and were considering a divert for emergency landing and maybe in the process of that diversion they became incapacitated due to smoke or fumes and it's plausible that the plane could have continued on for a while before being further affected by fire or running out of fuel at some point. either way, ending up in the ocean, which as barry shift mentioned a couple of minutes ago, is the likeliest possibility. the whole mechanical failure fire thing, like i just said, it's a dwindling possibility but

it is still there and it's certainly more plausible, meanwhile, than some of the other more fringe theorys that we've been hearing over the past couple of days. some of the more ridiculous ones, that the plane had tucked up underneath a singapore airlines jet so the two radar signals became one and then broke away on land somewhere. i hope at the very least, don, can we put to rest or at least move away from this idea that the plane is hiding in a hangar somewhere? there are a number of reasons why that is extremely far-fetched. >> some people believe every possibility should be explored. here's another scenario i want to get to about the fire and this is from henry. henry says, co-pilot is smoking as he did with aussie girl before, a fire started and he doesn't want to report it. an australian woman came forward

saying that she was in the cockpit. that was back in 2011. she said that she stayed in the cockpit the whole time and the co-pilot was smoking. richard? >> i don't know the truth of that. >> you know the co-pilot? >> i met the co-pilot. i've never met the woman. i have no reason to believe one way or the other. what i can tell you is that question goes to -- if -- let's just say you're right and you're talking about a fire in the cockpit. there's a fire extinguisher. this theory that a fire -- with a mechanical fault, it could be something else besides a fire that leads them to make that turn. the good theory, which we're talking about, has been talked about all day. it could not be just a fire but something else that leads to a mechanical that needs to return to ground. >> jim sciutto, can you talk to us about the supposed link between a pilot and opposition leader in malaysia? >> well, it's a former prime

minister of malaysia, anwar ib bra him, reporting that the pilot was politically active and anwar ibrahim said that he knew the pilot and in fact that they are distant cousins but officials i've talked to do not consider this a big deal. they do not consider it a big warning sign that that tie to that political movement would have caused him to do something. that movement is not radical in any way. i think it might be a red herring at this point. >> jim sciutto, thank you very much. everyone else, stay with me. you at home, tweet me your questions. use the #370qs. when we come back, should they search the home on a remote island with an airport?

welcome back, everyone, to our special report. we're answering your questions of flight 370. tweet us with #370qs. here with me is richard quest, jeff weiss, jeff beat tea, mary she yaf voe and patrick smith. here is what carolyn barnett says. often thieves get away with big least 77 would worth money in the black market.

>> there's a secondary market, you can go online and find them listed and they are not worth a gigantic amount of money. it's like $50 million for a secondhand 777. bear in mind, that is not one that is hot. you've got to file off the serial numbers and so forth. so there's probably easier ways to get your hands on a few million bucks. >> here is one from f.s. taylor. anyone been able to investigate the men traveling on the passports yet, any connection to the pilots? jeff beatty, you've been looking at that. and you've been taking another look at passports. >> i think that really leads to the question of were there people that were helping the pilots because first we have to look at -- and what you mentioned at the head of the show here about this report about the computer being programmed 12 minutes prior to

the good night call, obviously there was no duress signal given from the pilots to the people they were communicating with. and as my friend patrick and other pilots can tell you, there is a way to communicate duress not only with the transponder codes but also what you say verbally. so if in fact a decision had been made and they had been coerced and unwillingly turned the plane, they could have given a duress signal. they didn't do that. perhaps they did have other people on the airplane with them, they willfully made this course deviation and when we look at, well, who's suspicious, the mere act of taking and traveling with false passports certainly makes those people suspicious. >> okay. what about the fake or stolen passports? nobody is saying anything about it. could the plane have flown to iran? mary, could the plane have made it to the middle east, iran,

specifically? >> well, you have to look at not only could it make it through all of the different air space and through the radars and all sorts of civil defense but also could it just physically have made it there. we do know that they didn't take on -- the pilot didn't ask for additional fuel before they took off so it's got a range of 7,250 miles and unless they stopped and took on a whole bunch of jet a, it would be pretty pressing over the mountains. >> here is what michael says. what intelligence value to the employees of semiconductor china telecom and business machines zte and huawei? >> it's my understanding those employees had a background in sophisticated radar and there may have actually been at least one of those employees who had some piloting experience. so the fact that they were actually on this plane i think

is significant. but i'd like to go back to one other point that was made earlier. whether this turn was the result of a mechanic malfunction on the airplane or something else, i have to say, at 1:07 when the acars system reported that there was a program change for the heading in the airplane followed by 12 minutes later when the pilot made his infamous remark "all right, good night," pilots don't make their change in course mid-flight without getting permission from air traffic control. they had 12 minutes to talk to air traffic control and did not do that. i think that this -- this was a well-made plan. i think the fact that they said "all right, good night," putting the whole sequence of events together, you have an airplane

that was on a track to make a youturn, wanted to become invisible, i don't buy into the mechanical fire theory as a cause for this sequence of events. >> richard quest? >> absolutely. because what you now have is a direct contradiction in terms of all of the theories. they can't all be right. but if the preprogrammed 12 minutes earlier fact is right, then the mechanical turn around theory cannot be right as well because that preprogram -- and what i now believe is that that preprogram may not have actually happened when it was done in the flight management computer but may have been when the plane next reported in at 1:07 because when you report in, automatically your next waypoint and your next waypoint are sent along with it. >> and what i'm understanding

from producers now, cnn has now confirmed the preprogramming of the flight happened in the system. so it was an nbc report and now we've confirmed -- >> we have confirmed that u.s. officials believe it. yes. u.s. officials believe that is what happened, that there was a preprogramming. now, if that's the case, i would suggest it became clear because when the aircraft did a reporting automatically, it gave its position, its next position and the position after that. >> stand by, everyone. stay with me. we have lots more questions for you, including what we can learn from technology in this mystery. i'm also going to be checking in with martin savidge. make sure you tweet us #370qs. we're back in a moment.

so we saw martin savidge at the top of the broadcast. we asked him to do something. at this moment, he's in a 777 flight simulator along with flight instructor mitchell casada and he's answering a question from marcus. marcus says, the himalayas are vast. is it possible the plane could have crashed there where radar coverage may be spotty? martin, what have you got for us? >> well, essentially here's the scenario we set up. here are the him ma lay yeah mountains. we tried to simulate flying through them apparently trying to do it below radar.

in other words, using the mountain as kind of cover. the 777 was never designed to be a fighter aircraft and even though we're in a simulator and even though i know that none of this is real, i've got to say that the way that the whole horizon keeps banking is really uncomfortable. the aircraft is doing over 230 knots as we find our way through the steep narrow and mountain passes here. you can hear the warnings going off that we're way too low and even though we're 1600 feet in the air, we're actually only 320 feet off the deck. so try to fly like this for any great length of time, this is pretty amazing just watching. it is a simulation but if somebody was trying to do this at night, there's no way. you would end up on one of these mountainsides here. so it's impressive to watch but really this is just fantasy here. there's no way an aircraft like this would fly this low in the himalayan mountains, don. >> it is fascinating.

you may have heard richard quest mouth the words there saying it's fascinating. the question, martin, could it have crashed and still be there. you're saying, yes, it probably would have crashed and still be there but are they searching this particular area? >> i don't know. martin, do you know? >> i don't know, richard. let's face it, the himalayas are some of the most hostile places on the planet. >> we thank you very much for that, martin savidge. we're going to answer more. the boeing 777 just might be the most advanced commercial airplane there is. cot technology give us the vital clues we need to solve this? i'm back with my experts right now. it's jeff weiss, jeff beatty, mary schiavo and patrick smith.

with all of the technology in this world, why is it that planes don't have an unstoppable tracking device attached? jeff beatty, you have been talking about the communication on this plane that you say no one has been talking about involving countries jamming signals. elaborate on that for us. >> certainly. well, first of all, your viewer is correct. there is no reason why we could not put technology on that is impossible or highly unlikely for the crew to be able to turn off. we have that type of technology in the emergency beacons onboard the aircraft. that is something that we'll probably be looking at to do. i've been racking my brain, how do we explain the no cell phone calls, some of the other things where people were asking about tonight and last night and one of the very simple explanations is, jamming of equipment. now, in the old days that used to be something that only states could do.

they could do electronic warfare and jam cell phone transmissions but right now that is easily commercially available stuff that somebody may have been able to bring on the airplane, maybe even the cockpit crew, to keep people from being able to use their cell phones. you can go to a website, jammerfromchina.com and see these things for like 200 to $2,000 where you can knockout all cell phone communications. >> yeah. >> they sell them to prisons to keep prisoners from communicating. it is possible. mary talked about maybe they were not near cell towers. but there is this technology out there. >> i want to talk a little bit more -- i have another question for mary but it's just amazing, the questions are so smart from our viewers and they are coming in. what do you say we've gotten -- we get like 30 or 40 within seconds. >> they are running at 50 to 60

a second. >> yeah. so this one is for mary from tristan. why would one program a computer system if they didn't plan on landing somewhere? >> ordinarily you plan your flight come ut pooers for places you don't intend to land because you have to have emergency plans before you ever take off. you have to have enough fuel to get to your primary and secondary in case something happens. so you actually program and have flight coordinates for airports other than the ones that you're going to but it's to deal with emergencies or weather or problems at the airport and you can't get in. so it's just a backup plan. >> patrick, i want to ask -- let's see. this one is from keith. could the transponder have been reprogrammed to emit a different flight identity? >> no. no. and don, i want to back up a second. richard made a good point a

minute ago, it's real important that we establish the timeline, the communications timeline versus the acars timeline, make sure they match up and make sure that's accurate information before we start to rule out certain possibilities. meanwhile, mr. beatty made a comment a minute ago that i almost had to jump in. the reason a cell phone doesn't work from an airplane isn't because it's being jammed by a signal from a foreign country, it's because you're not near a cell tower. a cell phone just won't work from an airplane above a certain altitude and you're far enough from land. it's really that simple. certain airlines on their long-haul fleets have installed technology that does allow cell calling by collecting the signal and beaming it up via satellite and then back down to the ground or down to the ground through radio frequencies. i don't know if malaysia airlines has that equipment on their 777s, which would have allowed cell phone calling.

but in any case, it can easily be turned off. as we saw, all of this other communication equipment on the aircraft either being switched off or falling off line for another reason, the same would hold true for that. >> jeff, you can respond. because you were talking about cell phones. >> he was. >> all types of communications can be jammed this way. i was mentioning cell phones but we were also talking last night about the scenario if the plane had landed somewhere, why hadn't we heard from the passengers. so perhaps we haven't made that clear enough. that's the scenario i'm talking about. as patrick said, down below a certain altitude and you're in the vicinity of cell towers you can reach them or from the ground you can. if in fact the airplane landed or if it were low and people were trying to use their cell phones, i'm simply pointing out that there is programs out there that can jam cell phones but also other radio frequencies. >> stay with us, everybody. we've got a lot more questions

welcome back to our special coverage. i want to bring in cnn's chad myers to answer a question.

my theory is that the plane flew south into the indian ocean and landed on christmas island. it fits and it explains everything. >> what people are doing, don, is looking at those two red arcs. here's one here and another one here. they are looking at those arcs and trying to find a runway in those arcs and the closest one that you would find on the southern route would be christmas island. so here's where we are here. here's the last contact we had. here's kuala lumpur. the plane took left. at least we know that. after that, we don't know much. so the christmas island people believe that the plane took a left again and went farther to the south. let me take you down to christmas island because it's a very short flight. it's an hour or two hours away from where they were up here. this would not take very long to get to christmas island. so what were they doing for the other two or three hours that they weren't flying around? which don't know that.

and what we really need, don, we need to get our head around this, we need in mar sat to give us the other pings so we can see whether the plane was getting closer or farther away from the satellite so we know whether those arcs are really true. here's the runway right here. it's a mile and a half long run way. the island is not very populated, not very big. i don't know a place that i'd hide the plane on this island. here's an example of what i have here, the same spot, the same line. i fly you up the bay of bengal and all of a sudden i'm into the himalayas. what do i see? lots of airlines, lots of airports. airports almost right on the line here. this is 3,000 miles away and if we were evading radar at 500 or 1,000 feet, burning fuel like crazy, you couldn't get to these airports without either the refuel or more fuel on the plane

in the first place. that's what people are doing, they are looking for runways along that red line. >> chad myers, thank you so much that we don't know so many possibilities. i don't have to tell you that flight 370 has become a worldwide obsession. thousands of you have been tweeting us about it for days now and back with me now, my panel of experts, richard quest, mary schiavo and patrick smith. this is about facial recognition. the fbi -- can the fbi use facial recognition of surveillance through the malaysia airport security metal detectors for possible terrorists? >> that is one of the technologies that we hope that they are doing, not just facial recognition through the airport but anyone working around, supplying the plane, provisioning the plane, repairing it. yes, the fbi can do that and

hopefully they are. there was some -- there is some use of it in the united states, along the behavioral profiling. but, yes, and they should be doing it. >> this is from ian. i fly to mexico in a week and i'm a little scared to fly international. why hasn't the president or potus made a statement to assure the u.s. public that we are safe? >> is this something that we need to think about, arthur rosenberg, if we are flying out of the country? >> aviation is an incredibly safe way to travel. you know, when you travel from the united states to hot spots, i wouldn't call malaysia a hot spot but where you're not under the security umbrella of the united states, there obviously is a little bit more of a risk. but generally traveling to mexico, traveling to europe is an incredibly safe way to go. my personal feeling is i would rather fly an american flag carrier knowing that the quality

assurance of the pilot and the equipment are ruled by the faa and placed less confidence in the -- >> oh, no, no, no. i'm going to interrupt you on this. forgive me, sir. >> that's okay. >> i can't let you get away with that one. there are many international carriers. i can reel them off, singapore airlines, qantas, la opportunity sa. i cannot allow, forgive me, the suggestion that somehow a u.s. carrier is that much safer than one of the other major global carriers. >> well, the question, though, is about international travel. maybe the standards are better than in the united states, especially when it comes to israel. there is probably no safer place to fly. >> which would you prefer? a u.s. carrier or allow if you go to that area?

>> it's one of the most safest airlines on the planet. but notwithstanding your view, richard, i believe that american carriers and the quality, the auspices of the federal aviation administration, national transportation safety board, we set the model for aviation safety on this planet, allow included, don't know any other airline that has the same level of scrutiny control as what the united states government imposes on our airlines. >> we're going to have to agree to disagree on this. i'm not flying the british flag, but i am saying -- anyway, we'll agree to disagree. >> you do feel fairly safe. i get your point, arthur. i want to move on here. i want to talk about -- and chad myers mentioned this and forgive me if i pronounce it wrong. it says, has an authority other than the malaysian government

like our ntsb validated inmatsat ping data and maylay radar tapes? and i want to pose that one to patrick smith. what's the possibility about that? chad mentioned that and he said we need to get the other ping information from them. >> yeah, we're getting all sorts of garbled information, unconfirmed information. i think it goes without saying that everything needs to be put on the table and vetted a little more carefully before we have a stronger against of what happened. meanwhile, to back up a minute, i'm going to side with richard on that last argument about global air safety. >> you're not going to win, arthur, you're not going to win. >> it's safe to say that all global carriers are astonishingly safe. you start playing that game, compare country to country and carrier to carrier, it's an academic discussion. really, all carriers are safe. >> we'll leave it there.

your questions, your tweets are pouring in tonight and i want to get in as many as possible. let's get back to our panel. we're going to call this the lightning round. this one is from max. why is it assumed that flight 370 went down? is it possible the intent was to make us think the plane crashed? jef je je jeff wise? >> yes. i think this is evidence that there was a planned attempt to abduct this plane. it's most likely somewhere. some plane is probably unfolding and continues to unfold. >> lauren russell says, have any ships used sonar to detect any wreckage on the sea floor? jeff beatty? >> i have not heard those reports yet. i know sonar equipment is being used. the plane may be hot but there

may be great cargo. >> and could a satellite have hacked into the plane conducted altitude/waypoint maneuvers as a test? who is laughing at that? >> arthur. the answer is no. >> lauren russell said, is it possible that someone doing maintenance on the plane before it took off changed the flight plan leaving pilots unaware? patrick? >> no. look, we're going all james bond over this. i'm sure that what happened is a lot less elaborate than most of these theories. >> yeah. >> and i do not believe that the airplane is sitting out in a hangar. i do not believe that it was to be used later. it a fair riterrorist was going that, why not use the hundreds of cargo planes that move around the country anonymously. this is too high-profile for this. >> go ahead, richard.

>> starting off, why can't it just be a case of expensive misadventure? jeff wise? >> i'm not sure exactly what that means? someone having fun with it? just a prank? is that what that means? >> no, it's just that something just went wrong. but never mind. all these theories but what's the objective? what's the payoff? what's the motive? clearly one for arthur rosenberg. >> i'm in jeff wise's camp on this one. i think this was a well-conceived plan, was well-executed by smart people. we've been playing catchup since day one. the end game remains to be seen and i think this hasn't unfolded to its true wigs yet. >> mary schiavo, how do you lose a boeing 777 with today's technology but i can't park two minutes over at a meter without a dchl amn ticket?

>> meter maids. when you're over the ocean you have nothing but secondary radar and we don't have the aviation cops where we need them. >> go ahead. >> one for you, patrick smith. it comes from erica mcknight. why don't airliners such as flight 370 have any cameras on board or in the cockpit? >> i don't see how that would help sni don help. i don't see that germain to this. >> that would have helped. >> we're all playing arm chair investigators here. us and everybody watching. we just don't have enough information yet and we need to sit back and stop all of the crazy speculation and see what happens. i think we'll get to the bottom of this eventually. we might not, and people should be prepared for that, but i think we will. >> i think these are plausible

scenarios, not speculation, with all do respect. >> i think it is especially when we don't know anything. we thought it wasn't plausible that someone would crash airplanes into buildings and then they did and it suddenly became real. we're going to talk a little bit more after this. we'll be right back with more of your questions. gunderman group is a go. yes! not just a start up. an upstart. gotta get going. gotta be good. good? good. growth is the goal. how do we do that? i talked to ups. they'll help us out. new technology. smart advice. we focus on the business and they take care of the logistics. ups? good going. we get good. that's great. great. great. great. great. great. great. great. great. (all) great! i love logistics.

we're back now with our panel of experts and a pro found

question. and this profound question comes from patricia. could don discuss the power of mystery? agony of the unknown. planes, faith, those who differ from us. who wants to talk about that? mary? >> don -- >> go ahead. go ahead. >> yeah, this is jeff. i'd like to buzz in for the lightning round. you know, the word plausible scenarios was used. it's extremely worthwhile to do this because we've already learned things that the transponder, et cetera, that we could be doing better. in the year after d.b. cooper -- 15 copycats manifested themselves. we've got to get ahead of the copycats because they will happen. lessons we learn here ought to be applied quickly before we have to wait for the end to become apparent. >> yep. and this person brings up a very

good point. the power of history. the show is called "the mystery of flight 370" and it is quite a mystery. >> and i'm going to remind you, there were 239 souls as well. >> what happened to the 239 souls? i'm don lemon. thank you so much for watching us. "ac 360" starts right now. good evening, everyone. it's 11:00 p.m. on the east coast. nbc news is reporting that the notorious left turn that the plane made was not only programmed into the 777's flight computer but was punched into the computer at least 12 minutes before the first officer made his last radio contact with air traffic control. 12 minutes before the routine words from the flight deck all right good night. the implication if true is ep
