[Berman:] New information. Data deleted from the home flight simulator, The FBI is now reviewing the hard drive from that simulator with the question of who deleted it. What exactly was the data that was deleted and why delete it at all?
[Pereira:] Our Martin Savidge is inside a Boeing simulator. He has been there all week. He has pilot, Mitchell Casado there with him. Let's talk about this news, Martin. Being wiped from the simulator, does that raise any red flags to you.
[Martin Savidge, Cnn Correspondent:] I'll have Mitchell answer that. Let me just describe for the layman's understanding. A flight simulator is a big sophisticated computer. Instead of a key pad and a mouse, you are using instruments to input. Deleting of information from a computer?
[Mitchell Casado, Pilot:] It is very much like what martin said, just a matter of deleting files. It has no significant if they use the computer for other things, if they had home use computers, files, stuff like that, would you be deleting stuff.
[Martin:] What about a simulated route that does take a lot of capacity.
[Casado:] You have to delete and add more. I don't see any real significance for the deleting of files.
[Martin:] Or if you thought in some way you are hiding it?
[Casado:] There is that possibility but it is so normal. It is just almost like
[Martin:] I think really what we are saying is that the computer forensic experts are going to have to figure that one out.
[Berman:] They are looking at that and trying to retrieve the lost data. I'm sure they are also looking at lower data that wasn't lost, about where he was simulating flights to and what kind of operations he has been doing. One other bit of information, this 12-minute gap between when the pilot, co-pilot, someone in the cockpit changed the computer settings, 12 minutes later, the last point of vocal contact. Martin, I understand you have a demonstration to help us better understand that.
[Martin:] Mitchell, if you would, put us in flight. We are going to put the simulator in action here. So stand by. Remember, this aircraft is now programmed exactly like flight 370. We are on the way to Beijing. Everything about this is plugged into this system. We talk about the course change that as it is now being reported was implemented and inputted into the navigation system 12 minutes in advance. Is it possible one of the pilots did it without the other one knowing? Maybe. Maybe the guy was in the bathroom. Once they are seated at the controls, you look at this. This is the navigation display. Now, let's show you what should be here and then we will put in what would look like the route to Beijing. This magenta line, that's the way to Beijing. Anybody looking at that screen, even me, what do you see? This huge and very obvious turn. That turn is a major deviation away from the course. It was clear for at least 12 minutes from both perspectives. That change was coming. It is a red flag, a flare in the night. This plane is going to do something very dramatic. What does it mean? It means that both pilots were in on it or one pilot was going to make the turn and the other couldn't do anything to stop them. In other words, incapacitated.
[Casado:] Yes.
[Savidge:] Or it could be maybe they anticipated an emergency and were planning to make this turn. All we know for certain is, as you can feel, "All right, good night," and then the turn is starting. It was pre-programmed and they had to know it was there. The other thing we should point out, when it was entered into the system. The message was sent to Malaysia Airlines. They too should have known 12 minutes in advance their plane was going to go way off course.
[Pereira:] Substantially off course.
[Berman:] Completely different course all the way to the west.
[Pereira:] That was really interesting. I hadn't thought about the fact that maybe one pilot knew and the other didn't. If the screens have the same information and you see it change.
[Berman:] Of course, our thanks to Martin Savidge and Mitchell Casada. Ahead for us AT THIS HOUR, were the pilots looking to land because there was an emergency on board? This is a very popular theory. That's been burning up the Internet. It is on the Internet. Could it be true? We'll tell you what the evidence really shows right after this.
