RADDATZ: OK, thanks very much, Chairman Rogers. We'll be back with you shortly to talk about that standoff in Ukraine. But for more on the mystery of Malaysia Flight 370, let's bring in ABC's senior justice correspondent Pierre Thomas plus Colonel Steve Ganyard who is an ABC contributor, a former marine fighter pilot and also an accident investigator during your time in the military.
Pierre, I want to start with you. You heard what Chairman Rogers said about those passports. But what is happening now in terms of the investigation as far as the U.S. is involved particularly?
PIERRE THOMAS, ABC NEWS CORRESPONDENT: They're deeply concerned about those passports. They're trying to get as much as information as the chairman said. The surveillance video from the airport is going to be key. They'll use facial recognition technology to look at those faces and see if they can find any hits in the terrorism or criminal database.
The other thing is the flight manifest is key. They're looking at the pilot, they're looking at the crew members, they're looking at all the passengers looking for any hint of something that would be untoward that would suggest terrorism or something else.
Right now they say they have no direct evidence of terrorism, but they say they cannot afford to wait, they have to look at everything possible to try to get a fix on this.
RADDATZ: Steve, you as a mishap investigator looked at all of this. The idea that the pilot turned around in flight, do you buy that?
STEVE GANYARD, ABC NEWS CONTRIBUTOR: I'm still a bit skeptical. If you look at the radar tape, there's a bit of a heading change, but that heading change could be explained as he was turning on course, that he was just going on the normal course.
We also know that they're way out at the edge of radar coverage. So I've investigated mishaps in the past where we've had airplanes just disappear without a trace, and we've found that sometimes that radar data, especially at range, is unreliable.
RADDATZ: No mayday signal. What does that tell you? What might -- if it was a catastrophic failure, mechanical, all those things that David brought up, but no mayday signal. Why not? What do you suspect here?
GANYARD: It's hard to suspect anything with a certainty. But we do know that if something catastrophic happened and the airplane blew up, obviously there would be no mayday. But if there was a problem in the cockpit -- let's set the scene. It's at night. Middle of the night, literally middle of the night, out over the board ocean, black, no horizon, the auto pilot is on, things are probably calm. Perhaps something happened in the cockpit. Maybe there was a major malfunction. The first thing the crew is going to do is fly the airplane.
In aviation we have a saying, "aviate, navigate, communicate." So the last thing that would be thinking about would be talking about what was going about what was going on in the cockpit. If they have a problem, they're going to take care of it and they'll talk about it later.
So, maybe there was a period in there where something catastrophic was happening and they just did not have time to communicate that.
RADDATZ: I think it's extraordinary that we don't know where that airplane is. We have GPS in our cars, we have all these things, and yet they cannot find that airplane. In fact the last radar contact they have, it could be way beyond that, it could be anywhere.
