The airplane for four years and now retired said hes never been down there. >> is that right? >> because theres no real need for us to be down there. theres one circumstance that i would go down there and thats simply after an incident theres a diagram on where to pull a particular circuit breaker like whats 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 woul...

Wait a minute, theyre not going to beijing anymore? >> if they entered the change and entered it in and started acting on the change they should know it if acars was still working, sure. >> right. so keith, what is your prevalent theory? the one that everybody came back around to today was some sort of catastrophic smoke in the cockpit. maybe a tire fire so the pilots put on their masks, theyre pulling circuit breakers, i guess, to try to isolate where this electrical fire is coming from which t...

Mechanic john goleo. were know not showing our viewers any secret information. this is all information that somebody who is very interested in this can find out online and elsewhere. i just dont want to give people the idea were showing something we should not be showing. jim, this compartment where the computer maintenance system is known as acars, walk us through this, show us what it looks like. every plane is different, but how would someone go about disabling the system? >> reporter: i like...

Cockpit. maybe a tire fire so the pilots put on their masks, theyre pulling circuit breakers, i guess, to try to isolate where this electrical fire is coming from which then cascades, shuts down the transponder and the radios. go. what do you think of that? >> well, i think thats a little bit far fetched. certainly based on the last radio communication that was received, it didnt seem like they were in any sort of distress. when you put on the oxygen mask and then attempt to talk on the radio, t...

And thats very important. >> true. and even though i might be a little more intimate with the systems on the airplane, this is not an intimate part of my knowledge. >> as a pilot -- >> this is not a place that i view. a friend of mine after being on the airplane for four years and now retired said hes never been down there. >> is that right? >> because theres no real need for us to be down there. theres one circumstance that i would go down there and thats simply after an incident theres a diagr...

You get here, these are the actual components. this one, john has told me, is the component that keeps the cabin pressurized, for instance. up here this is the one where the plane would identify itself to other planes if it got too close. all you have to do is unscrew these blue nobodies and pull the component out and the systems disabled. right here within reach climb down the stairs. two ways to disable key systems on the aircraft. >> point out the circuit breaker. point out you can see right ...

Difficult to disable systems. but its really not. first heres how you get here this. little ladder here comes down from the cockpit so youd open that trap door, walk down the stairs and then youre in the avionics bay here. and here on the right side, circuit breaker board looks kind of like the circuit breakers youd have at home. simply pulling out one of those black knobs disables the system. all the systems are labelled along here. then on this side of the bay as you get here, these are the ac...

Know to expect the plane. but its not like theyve been watching the the whole way in vietnam. they are expecting to sign within the next couple of minutes and dont become concerned until i dont see that airplane anymore, it hasnt checked in with me. it was around that point the acars gets pulled and the transponder and turn. it sounds like something quite well planned out. the idea that someone walks in the cockpit and does all of this methodically takes a leap of imagination, which is why exper...
