martin savidge standing by for us in a boeing 777 simulator. martin, take it away. >> all right. let's show you first of all the description it's a sharp turn. here's what we would say a sharp turn in an aircraft like this would feel like. taking off. and you see the alarm that goes off? it's warning that we're already turning more than this airplane really should. and you can see by the horizon, you know, this is very dramatic. what's the degree of turn here? >> this is about 40 degrees. >> that's a really sharp turn. now set it back up straight. put it on autopilot again. because, remember, the information that this source is giving us, it says that that turn took two minutes to complete. that is a very long time to make a 90 or even 180 degree turn. an extraordinary amount of time for this aircraft. in fact, we'll try to give you a sense of what that kind of a two-minute turn would feel like. and this is it, right? we're doing it now. it's barely perceptible. it's slight. you'll get it. but if you were a passenger, once we straighten off, you would not sit here and say, boy, t

for a look at what might have happened inside the cockpit, cnn's martin savidge joins us from inside 77 simulator. take it away, martin. >> good morning, carol. even though it is a simulator, it does feel when you're sitting here very much like the real thing. let me tell you what we have done. we set up the simulation as close to what we know as was going on with flight 370. we took off from kuala lumpur 45 minutes to an hour ago and following the highway in the sky. we're on this pink line right here you can see on the navigation system. the reason we're not touching the controls is just like 370, we're on automatic pilot. we're currently up at an altitude of 35,000 feet. so everything that we know about the plane at the time it disappeared, we are sort of re-creating and reliving here. let's talk about some vital equipment. a lot has been said about the transponder. where is it here? it is actually located right here, right beside me. relatively small and looks rather obscure but vitally important. mitchell is my pilot on this flight. mitchell, explain why the transponder is so imp

we're taking you back into our live simulator with cnn's martin savidge. martin?we're going to show you what this turn and what this descent could have looked like and what it may have implied was going on inside of the cockpit. we'll show that to you in a minute. gests cell health plays a key role throughout our lives. one a day men's 50+ is a complete multivitamin designed for men's health concerns as we age. with 7 antioxidants to support cell health. one a day men's 50+. and better is so easy withrning you cabenefiber.o something better for yourself. fiber that's taste-free, grit-free and dissolves completely. so you can feel free to add it to anything. and feel better about doing it. better it with benefiber. here, announcer: athe moment babies are born, their brains are forming the connections that determine how they learn...think...and grow. in the sky.

so we're going to martin savidge to see what that might look like from the flight simulator. in that idea what it would look like due to a loss of pressurization or some other incident. >> reporter: ghost plane, zombie plane, plane without a brain. it would begin with maybe some kind of an alarm that would go off. could be fire, could be sudden decompression. either way. we're simplifying this greatly. pilot mitchell here puts it into a very steep descent. at the same time the aircraft begins to turn. the idea you want to get this plane heading back to some airport. we were over water at the time so either back to kuala lumpur or the closest near by. but you're descending primarily because you've only got so much oxygen. pilots would already have their emergency oxygen on board. if it's a sudden decompression, the passengers have had the masks flopped down in front of them. they only get about ten minutes. you've got to get down quickly to an altitude where people can breathe. in this case we're saying 12,000, but even per would be about 10,000 feet. but for the scenario you s

let's bring in martin savidge and mitchell casado. believe this plane made a water landing. you were going to take us through you that. tell us how plausible that is. >> there is some plausibility to it. we have to understand, this plane flew a long distance on, we think, autopilot and then would have run out of fuel. as we talked about before, even as this plane ran out of fuel, it doesn't just sort of pitch over and suddenly nose dive into the water. the aircraft, thanks to the great engineering of boeing, is designed to fly level even without the engines operating. it is going to descend naturally. it is still going to try to fly straight, level, and slow as it descends. for the reason you are hearing the alarms right now is the fact that what we are showing you hear is that we made an approach toward the water. mitchell, we are 240 feet above the water. our speed is about 235 miles an hour. that would be disastrous if we touched down. this is the kind of approach. you are coming in low over the water and what do you want to do if

our martin savidge live in a flight simulator. flight trainer next to him. a familiar thought we've seen you in. i wonder, martin, if you could help explain to our viewers the significance of the new information about the last acars transmission and sequencing as it would play out in the cockpit. >> it would certainly seem to downplay some of the sinister sense you would have gotten if somebody preprogrammed a turn. let me show you what we're talking about as far as being able to point it out on the dash. this is the acars system. a system does many things on the aircraft. it allows pilots to send text messages to the ground, allows the ground to do the same with them. an alternate communication system. most important for this scenario, that system would report to the ground every half hour or so parameters of what this is doing. speed, altitude, direction. it did that at 1:07. at that point everything was good. if there was a preprogrammed change, it would have been entered in this thing. this is the flight management system. essentially a robust gps. you c

so we'll go to martin savidge to see what that might look like from the flight simulator. rtin, explain that idea, what it would look like due a loss of pressurization or some other incident. >> reporter: ghost plane, zombie plane, plane without a brain. it would begin with an alarm, could be fire or sudden decompression. pilot puts it into a very steep decent. at the same time the aircraft begins to turn. the idea is you want to get this plane heading back to some airport. so we would head back to kuala lumpur or the closest airport. but you're descending, because you only have so much oxygen. the passengers have had the mask flop down in front of them, they only have about ten minutes. so you have to get down to an altitude where everyone could breathe, 12,000 or 10,000 feet. but for this scenario, you stabilize. you get the aircraft back into a reasonable position. you level off. you apparently have figured out it's not that severe and you get it on automatic pilot or you put it on automatic pilot and you're overcome by smoke or lack of oxygen. you pass out, passengers p

martin savidge joins us.nderstand we're about to see how this might have played out. >> what i've been told, here's what happened in our scenario. we've had a sudden massive decompression. so i want him to get the plane down to where people can breathe. and get us 180 back the other way so we can land. so tell me how this works. >> throttle title. we start deskrenl and a turn. i would be on the radio letting them know what's going on. >> i'm telling you a check list. >> of course. yes. one of them talking about the, both the brake, how fast we're going down. the idea is we have to get it down for passengers to breathe. we've got a limited amount of oxygen ourselves. i believe it is 15, 12 minutes. >> idea is to get below 10,000 feet so we can talk with air traffic control and assess the situation. that's the bottom line. >> we're now passing 28,000. >> i wouldn't be overspeeding the airplane. that's the danger of pulling it apart. but a rained decompression so there might be a hole in the aircraft. any oversp

martin savidge is out front with the final clue. martin we use this word ping.w, ate pretty complicated thing what we're talking about. this could be incredibly significant this use of the word partial ping. >> reporter: right. as we know there were at least six pings that came from the aircraft during its flight that have been analysised by the folks at inmarsat that came up with this fact that the plane went on this southern trajectory and able to discern this plane went into the southern indian ocean. if you find that last ping it's believed to have been transmitted very close to the end of the life of the aircraft. find where that ping is in theory then you would be in the neighborhood, i won't say right on top but in the neighborhood of where that plane went down. not where the debris is that you're finding but maybe where that plane went into the water and of course it's the plane that has the black boxes that has the information that could be key to solving what happened. >> so kit tell you where it went into the water but you're implying due to time, cur

and we have mitchell cabrera, we saw him all last week with martin savidge. great reporting by him and martin. hans, i want to start with you. let's talk about the jet's acar system, the aircraft's communicating and reporting system. at this point, can it lead investigators to this aircraft? >> it's doubtful, because it doesn't seem to be functioning. it seems to be turned off. somehow compromised. also, the satellite communication element of acar which is available technically but not all airlines describe to it because it is expensive. i don't know whether malaysian airlines subscribed to the satellite communication. it appears from what i've heard, it appears that maybe at one point they subscribed to it. the airplane was properly equipped with that capability. but it seems to me that currently they're not subscribing to that satellite communication aspect of acars. >> so, then, hans, what about the signals or the pings from the cockpit. what are they looking for depending on if the plane is in water or on land? >> well, are you talking to the so-called pin

cnn martin savidge is in a boeing 777 simulator outside of toronto, representing the exact flight fromakeoff to disappearance. martin? >> bill, let me just show you where we are. we took off 45 minutes ago, simulation, kuala lumpur. we're now 4.4 nautical miles away from this reference point in the navigation. it's a point in the sky. but for this story, a critical one. it is the last point at which flight 370 actually was known to exist and still be seen on radar. it was actually at that time or shortly after that waypoint that the crew radioed in and said, already, good night. and it was shortly after this particular moment that we began to see some failure of systems on board, especially when it came to navigation. what we've done is taken the simulator and we've plotted in everything that we knew about that flight, the time at which it took off, the root in which it followed, it was headed to beijing, the altitude, we're at 35,000 feet. nobody is touching the controls because right now we're flying just as they were at that time on automatic pilot. everything set to try to replicat

martin savidge, mitchell casado, thank you for giving us an insight.t is such a valuable thing. >> people have so many questions. one of them was, this plane is turning so radically. >> ahead at this hour, ta third of the passengers on that jet are chinese. china deployed even more in the search. why this may be about more than just helping the victims. >> the search area spans more than 2 million square nautical miles. crews are looking at two distinct tracks now. our next guest says they should probably stick to just one of those. if you have moderate to severe rheumatoid arthritis, like me, and you're talking to your rheumatologist about a biologic... this is humira. this is humira helping to relieve my pain. this is humira helping me lay the groundwork. this is humira helping to protect my joints from further damage. doctors have been prescribing humira for ten years. humira works by targeting and helping to block a specific source of inflammation that contributes to ra symptoms. humira is proven to help relieve pain and stop further joint damage i

martin savidge is live in a 777 simulator right now.s is becoming the center of this entire story. i guess could you talk about first what it would be like to fly at 45,000 feet above the 43,100 foot approved level of this 777 plane? >> reporter: yeah, the real problem we're having here, because we've been trying to emulate in the simulator here what's been reported, it's almost beyond the laws of physics and the physical ability of an aircraft to do at least what has been described in the article and described by those radar signatures. we're at 45,000 feet. the automatic pilot won't go this high. the airplane was never designed to fly this high. let me show you the controls we're dealing with here. these yellow lines, one on top, one on the bottom. normally they should be far apart. what this indicates, this aircraft, at this altitude, is teetering on the brink of disaster. it has to be flown manually to reach this altitude, and we should point out that mitchell is flying. what would the controls feel like at this altitude? >> very, v

and also joining brett and me, once again from our virtual cockpit in canada, joined by cnn's martin savidge and flight instructor, mitchell castado. brett, first and foremost. when we hear the fbi is now combing a hard drive of a flight simulator, how much can you comb? what kind of forensics can we actually get out of this thing? >> you can get literally anything that was on that computer. so anything that he threw out. even if it was just as simple as his web history and he deleted that. that is going to show up on the marred drives. data goes on to a hard drive the same way frosting goes on to a cake. one layer at a time. and when you take a chunk of that frosting away, delete a file, it just creates room on the hard drive where more data is going to override it. >> if you're a person of this caliber, this is a tech guru. wouldn't he be savvy enough to delete the right way, meaning delete forever? >> yeah. but delete forever, in order to do that, you have to physically remove that hard drive from the computer. you have to drill holes, put glue in between the platters. so if the fbi is go

martin savidge is live in a 777 simulator now. martin, this is becoming the center of this entire story. i guess could you talk about, first, what it would be like to fly at 45,000 feet above the 43,100 foot approved level for this 777 plane? >> yeah. i mean, the real problem we're having here, because we've been trying to emulate in the simulator here what's been reported, it's almost beyond the laws of physics and the physicaling ability of an aircraft to do at least what has been described in the article and described by those radar signatures. we're at 45,000 feet the automatic pilot won't even go this high. the airplane was never designed to fly this high. let me show you the controls we're dealing with here. these yellow lines, one on top, one on the bottom. normally they should be pretty far apart. what this indicates, this aircraft at this altitude is teetering on the brick of disaster. it has to be flown manually to reach this altitude. we should point out that itch mel casado is the one flying this. what would they feel l

. >> martin savidge joins us from canada, right outside of toronto.e have been watching you in the 777 dock simulator. we want to talk to you about the investigators claim that at one point, flight 370 was climbing up to 45,000 feet and suddenly dropping to 23,000 feet. explain how that would happen and what it would feel like. give us some insight. >> well, micayla, we have programmed that very kind of scenario in. first of all, 45,000 feet way above what is the normal operating ceiling for the 777. to get the plane up to that altitude, we have to take it you have aof automatic pilot which means mitchell is flying this manually. let me point out something on the navigation dial is the best way to put it. you have two lines. if those touch, this plane is going to fall out of the sky. we are on the razor's edge of flying almost too fast but at the same time almost flying too slow. a very delicate balance act. what do the controls feel like at this altitude? >> i wouldn't use the term flying very loosely. this isn't quite flying. this is almost falling.

martin savidge is again in a triple 7 simulator. hrough what would have happened in the cockpit if the crew was overcome with smoke or fumes or had to handle an emergency like that. >> well, what we will show you is what should happen and then you will know the differences of what we know of 370, and like 370, of course, on the route to beijing and taken off from kuala lumpur and we would have reached that point coming out of kuala lumpur where you turn off of the fasten seat belt, and then the crew would be up here where everybody in the back is relaxing, and then we would get something like that where there is an indication of the problem. that is the alarm. and then a screen readout that says where the fire is located and for this scenario, say in the forward cargo area, and the delegation would be to the captain, and mitch would be now trying to get us down as low as possible, because smoke could come into the cockpit, and we want to be in the place where we can open up the cockpit window to let the smoke out, and we would have o

martin savidge and our pilot mitchell join me inside the boeing 777 simulator. onversation has been going today towards how to ditch an aircraft in water. if you're in crisis and have no communications, can you bring a plane down if you're low on fuel and save the people on board? can you walk me through that with mitch? >> we can. you know, warn you we're not experts, either one of us, on that particular. but we can give you an idea of what it would feel like in the aircraft, what the aircraft might be doing. we can't take you all the way down to the water because this won't simulate it and even if we did out of respect of families who might be watching, we won't do it. we're actually over the southern indian ocean, that's all programmed in. remember, we're trying to emulate 370 as much as we know. we're about currently 906 nautical miles southwest of perth. so we're in the rough area of that debris. if you would just take us down lower. we're going to go from, where are we at? we're about 7500 feet. this is going to be a sharp turn. and then mitch is also at th

martin savidge is back inside a flight simulator to walk us through some of the details. ard quest also joins us, spent time with malaysia airlines before this incident. martin, you've been taking a closer look at the maintenance information system known by the acronym acars. tell us more about it. >> yeah, this is one of those things that up until now the average flying public knew nothing about but of course any pilot at least on an aircraft like this would know. acars. think of it as an alternative way to communicate outside of the traditional radio systems. i can access it here if i look at this screen and pull it up. here i've got a simple menu. it's possible here to amover a mouse. a pilot could send a text message to the ground or the ground could send a text message to them. this is good when the aircraft is far out at sea and maybe radio communication can be spotty. another way to access the system, same acars, but this is a different backup unit, is to go in through this, what do i call this mitchell again? >> control display unit. >> control display unit. i hit

cnn's martin savidge took these new details, these brand-new details we have about the flight, he took it into a flight simulator. and he says while the turn may have been sharp, it's not likely it happened as quickly as you might think, and the passengers may not have noticed a thing. >> reporter: the information that this source is giving us, it says that that turn took two minutes to complete. that is a very long time to make a 90 or even 180-degree turn, an extraordinary amount of time for this aircraft. in fact, we'll try to give you a sense of what that kind of a two-minute turn would feel like. and this is it, right? we're doing it now. it's barely perceptible. it's slight, you'll get it, but if you're a passenger, once we straighten up, you would not sit here and say, boy, like, this is something very, very wrong. this is a subtle, slow turn. it's sharp in that it will deviate you from the course to beijing eventually, but the perception that you're like banking, that's not what the simulator reflects on that. all right, so, let's go into the altitude issue. remember, the plane

martin savidge is live in a triple 7 simulator with mitchell. the latest reports we have right now are that that reprogram of the route happened about 12 minutes before the last communication. that all right, good knight. which again for those saying people in the cockpit knew was going on lends itself to that belief. how easy is it though for anyone to reprogram a flight in the cockpit you're in right now? >> well, we can show you that here in the simulator. it's quite easy. it's another piece of the avionics gear to learn about. this time the fms or the flight management system. it's here. there's one up in the pilot's position and one up forward here. essentially it does a number of things it assists the pilot and co-pilot in flight. the purpose of it being a gps or really good gps. it would be preprogrammed before the aircraft takes off with all the necessary information to get it to beijing which that was the flight plan for 370. but once they're in the air, it could be changed and mitchell, show us how easily that's done. >> very easily. t

but they may be looking at it, that, you know, a normal flight simulator, like the one that martin savidge has been reporting from, costs about a quarter million dollars. the one he had in his home was home-made and maybe cost $6,000. and lacking additional sophistication, it really becomes more of a computer forensic search, which the police does all of the time. so it's not so much the sophistication of the gear of simulating a flight. but what gets programmed into the software. i mean, using the software and the hardware they could look at and is see the previous routes. >> but malaysians, i don't think there is anything sinister going on and they're well-intentioned. they don't have the experience to undertake a massive investigation like this. i assume you agree. >> well, i agree that, you know, this is -- a huge investigation compared to anything they have seen. >> probably never done anything like this. peter, i want you to weigh in, as well. hold your thought for a moment. i want to take a quick break. our experts are going to stay with us. thai officials shedding new light on what

martin savidge is in the flight simulator. martin, let's start with you. the idea that the turn was entered into the system at least 12 minutes before the "all right, good night," how does the pilot put the turn into the night management system? how complicated a process is it? >> reporter: well, if you know what you're doing it's pretty easy. let me point it out to you, show and tell here. this is the flight management system. one of the consoles here. actually three of them right in front of us. but this thing does a lot of things on this airplane. it primarily makes the job of flying for the pilot and co-pilot easier. think of it really in this sense as a gps, really beefed-up gps. prior to takeoff you would have loaded in all the coordinates that were necessary, the waypoints for this aircraft to go from kuala lumpur to beijing. every turn, every aspect of that flight would be here. however, once in the air you could alter it. you could change it in fact, mitchell, you can point out how simply that's done. >> very easily, martin. this magenta line here

. >> reporter: in the sim yu ulat pilot mitchell casado shows martin savidge the route. and programming the simulator how to fly to the destination. >> so it will take this plane essentially from kuala lumpur to beijing. >> reporter: and the plane is ready, and before taking off, paul weeks sends a message home. >> the last line says that this counts as one day, so it means that it is only 27 days until i see you all again. >> reporter: around 12:30 a.m., malaysian airlines 370 flight pushes back from the gate and eases toward the runway and the aircraft is cleared for takeoff. >> all right. so the brakes are off, and everything is set. >> reporter: the captain booss s the massive engines. the plane roars into the sky. its altimeter tracking the time through 5,000 feet and then 10,000 feet, and then airborne, the air traffic controllers pick up the flight. >> they will see you on the radar, because you have a squawk code in the transponder which is going to turn the simple radar return into something that has a lot of information on it. it includes the flight number and

i want to check in with martin savidge. he is in a 777 flight simulator. martin we have a twitter question from kyle and it's about the 370's flying altitude. why did it drop below 2 12 -- 12,000 feet and fly for seven hours? >> one of them the plane descends and the plane turns. in one way it looks like an emergency and another way it looks like something else. >> we still don't know what happened to flight 370. and we have not found any part of that plane. i'm back now with richard quest and cnn aviation analyst miles o'brien. jeff wise, arthur rosenberg, also mary schiavo, an attorney for victims of transportation accidents. captain bobby skoaly, richard, despite what malaysian authorities are saying are we any closer to finding this plane? >> we are a lot closer to knowing the whereabouts of the aircraft. what the inmarsat evidence today along with the aaib and what we learned from the malaysian government is we can rule out the northern corridor. this plane went down in the southern corridor and by the words of the inmarsat, in the south indian ocean.

also go back to martin savidge in the 777 simulator.through the scenarios of how 370 could have made it to the isolated waters, if, in fact, it did. if so, what were the plane's final moments when it ran out of fuel been like? how the plane could have gone down and how it went down could tell investigators just what happened in the air. those stories and also talk to cnn safety analyst about this important piece of solving the mystery of flight 370. an emergency locater transmitter or elt. what it does and how it could be helpful in an investigation like this. that's all at the top of the hour, erin. >> looking forward to that, anderson. >>> we continue with the breaking news coverage on the search for flight 37p 0. heading to the possible debris site. now, as i said, takes a few hours to get out there and then look for a couple hours and get back before it runs out of fuel itself. shows what officials say could be debris from the missing jet. two pieces, one about 16 feet and one about 79 feet long. all of these about 1,500 miles off t
