And that is no small challenge. >> yeah. like you said, the signals are coming, they know, from 15,000 feet below the surface. they want to send a robotic sub messable down to look. but the under water search zone right now on the sea floor is 500 squire square miles, the size of l.a. they say it would take two months. and your concern is the recording might be blank. >> well, there certainly is the possibility. i mean, if you followed the concept that these were hijackers, some nefarious activi...

We had that one time where the captain of that particular flight decided to pull the circuit breakers. what he did was when he pulled them, they stopped recording. but what we found on the cockpit voice recorder was the first two hours of the flight when he arrived at the airplane, he was talking to the first officer, talking to the crew. we got some very valuable information even though we didnt have the actual part of the flight where he took the airplane down. e we did have very good informat...

The captains background or in his flight simulator that indicates anything amiss. but there is this -- the performance of the aircraft, how it got into the ocean hopefully 1,000 miles, if were looking in the right place, from perth, is inexplicable and has to involve some degree of human kror. >> mary, when they do find the black boxes and i think they will. five separate signals have been picked up in one general area, although its a large area. it seems like theyre going to find those black bo...

Breaker in the cockpit. if it was turned off just before or just after this incident began, we would hear everything up until that point. if it wasnt turned off, all of that would be lost. but we would also have everything up until the point of impact for the preceding two hours. >> and that will be interesting because the transponders were turned off. one might assume if there was foul play, they might have also pulled those circuit breakers. kind of a morbid question, but if they were ever abl...

About smoke or increased temperature, and none of that happened. >> well, see on the flight data recorders but theres a chance when they get the recorders, if that was an act of piracy, there may not be data on the recorders if they pulled a couple of circuit breakers. >> only a half hour of voice recorder. >> there should be two hours on this airplane. >> doesnt help much. >> were talking four or five hours. >> before we go. both jet engines, except by some extraordinary happenstance, would not...

In your house with circuit breakers. same type of an idea. but the question i have is, again it has been a while and i dont have the manuals in front of me. does the number one radio, the captains radio, come off the emergency bus that would be powered at least by the battery in case of failure of the other buses? is it separated that way? >> my understanding is it is connected to the primary bus. im not sure if youre referring to the hot battery bus or the emergency power bus. i dont think it i...

Dealing with enough time to communicate on the radio or one of the scenarios for dealing with smoke in the cockpit, for instance, is to shut down all the circuit breakers, so that would explain the loss of communication, loss of the radar, everything else from the plane, and turn them back on one by one to isolate the problem. >> maybe they didnt get a chance to turn them back on, is what youre saying? >> they could have, but what im really trying to do is explain why everything went off all of ...

Deep. they revealed pilot error as a factor in the crash. the black boxes are actually bright orange to make them easier to spot. they are located in the planes tail and can only be disabled by pulling fuse-like circuit breakers in the balk pit. the flight data recorder logs about 25 hours of information, hundreds of details about the flight, including time of day, directions and turns, air speed if the plane is nose down or nose up. the cockpit voice recorder captures private conversations from...

Of feet under water and their batteries are only required to last 30 days. >> it is a needle in a haystack and obviously it becomes substantially more difficult to find them once the pingers have gone silent. >> reporter: the flight data recorder tracts more than 80 points of the flight including the pitch, altitude, cabin pressure and auto mags codes and whether they turned manually or autopilot or a combination of both. that information is essential in figuring out what happened. >> theres a r...

And east. now are looking off the coast of australia. district other part of this, everybody has been trying to make sense of something that is a real mystery and as a friend of mine pointed out who is a captain for fed ex, he said if the guys really did steal that airplane, if this was a pilot suicide and one tricked the other out of the cockpit and locked them out, if they were smart enough to do all of that, they were smart enough to pull the circuit breakers on the voice recorder and flight ...
