reason the signal wasn t sent. it may be the signal was sent but no one was listening, 1:20 in the morning over the pacific. in the case of payne stewart, no distress call either, just sound of alarm including one for loss of cabin pressure. what is behind the credibility of the zombie plane theory is whether or not you believe this is an investigation into the mechanical failure of this flight or the investigation into a criminal ac. the difference between whether you believe the crew or someone else switched off the aircraft system or they would have failed, which would have given everybody on board little time to respond or even survive. jim. so this new information there was no indication coming from the plane this turn was preprogrammed, does that increase the possibility of a zombie flight? does it add weight to that? it s interesting. i talked to aviation analyst. gives weight to the possibility there was a mechanical area.
ended up. and that is why one theory continues to persist here. it is the ghost, the zombie plane theory. it involves the pilots becoming incapacitated, the plane flying on auto pilot, ultimately descending onto the ocean when the fuel runs out. cnn s martin savidge live in a flight simulate tore test our theory for us. what did you come up with, martin? don, there are a couple of variations that can be done on the theme of the ghost plane or zombie plane. it could be a decompression, sudden decompression that incapacitates the crew. in our scenario it s going to be a fire. but whatever, you re at altitude, you re flying along, there s been no problem with the flight so far, everybody back in the passenger area is relaxed and settling in. and then all of a sudden you get some kind of alarm. for us, it s the fire alarm that goes off. this immediately sets off a series of almost automatic events. the copilot and pilot would begin delegating here. we d say, all right, you fly the plane,
if the zombie plane theory is true, what would the condition of passengers be? would they be overcome by fumes, as well? why is there no satellite footage showing this plane from the time it disappeared just like there is of alleged debris? and what is the next step if no wreckage is found? is it piracy? let s go wright to pamela brown and richard quest. it is morning in the search area. what is the very latest now? reporter: from what we understand, the planes are in the air. right about now is when we should be getting the very first planes approaching the critical area. it s about four hours for the plane for the first plane to fly down there.
we ve got top aviation and security experts standing by to answer them throughout this hour. like this one. if the zombie plane theory is true, what would the condition of passengers be? would they be overcome by fumes, as well? why is there no satellite footage showing this plane from the time it disappeared just like there is of alleged debris? and what is the next step if no wreckage is found? is it piracy? let s go wright to pamela brown and richard quest. it is morning in the search area. what is the very latest now? reporter: from what we understand, the planes are in the air. right about now is when we should be getting the very first planes approaching the critical
it, i think that there was a lot they weren t saying but they did give us a clue they had done an awful lot of work and they felt fairly certain that they had something worth this effort. right. well, if the four of you would be kind enough to hang out with me, when we come back we want to turn to the theory people are now talking about as a result of this find. the zombie plane theory. what is it? could it explain anything? we ll explain next. predibut, manufacturings a prettin the united states do. means advanced technology. we learned that technology allows us to be craft oriented. no one s losing their job. there s no beer robot that has suddenly chased them out. the technology is actually creating new jobs. siemens designed and built the right tools and resources to get the job done.
