down, what we might call patting a person down that really was patting a person down. that was not a screening. most of the passengers supposedly have been cleared by their countries of any terrorism connections, as have the pilot and the co-pilot. so where do you go from there? well, i m not willing go anywhere from there. just everything that, if you remember back when we talked about looking at everything from the time the plane was on the ground and make sure you don t tunnel vision because of the passports, don t tunnel vision now because something is erased off of his simulator. i mean you erase things all the time on your computer, telephone and other things. still you have to look at it. but it s clear, it s just as an investigator over 40 years, just it tells me it s one of the two pilots or both. but it s very unusual it would be both. that s extremely unusual. one either had to be inokka
different waypoints. here s your keypad and screen. you pre-program it before you take off. in this case they were going from kuala lumpur to beijing. but it s being reported at some point it seems after they took off and once they were on their way they made a change in their course. now to do that it isn t that hard. just some key strokes. a matter of punching in a few key strokes, five or six for the destination and you enter it into the flight plan. it will ask you are you sure you want to do that. if you are sure you press execute. reporter: when the plane does that, we should point out. it s been described as a very hard turn. really doesn t feel that way when you re on board in the simulator. actually like a passenger you would think oh, a normal turn in the sky. you wouldn t necessarily know that the aircraft is now deviated, well strongly away from what was the beijing destination. we should point out, carol, that
head or something like that. that capability exists, i believe, in most 777 cockpits. it s a tough question, i know. thanks for trying to answer me. steve wallace, thanks to you. another bit of information that could prove important, data was deleted from captain shah s homemade flight simulator. it was in a youtube video sitting in front of his homemade simulator. the malaysian government says data was deleted but they didn t say who deleted it. for the families of the missing passengers, frustrations are boiling over despite the perceived inaction from the malaysian government. still at the heart of the story are people, someone s mother, father, fiancee. today, anger and desperation erupted. just a few hours ago, a passenger s mother broke into a
giant task. if you want to know how hard it is. i say look out the window of a plane when you fly over the water, you couldn t even see an ocean liner down there and it looks like a speck on the water. that s huge. tom foreman reporting live for us. another bit of information, data was deleted from captain shah s home made flight simulator. that s flight 370 captain in a youtube video. the malaysian government seized that simulator and says data was deleted but did not say who deleted the information. i would like to take this opportunity to state that the passengers, the pilots and the crew remain innocent until proven otherwise. cnn aviation analyst and former inspector general for the department of transportation joins me now. welcome, mary.
