codes but also what you say verbally. so if in fact a decision had been made and they had been coerced and unwillingly turned the plane, they could have given a duress signal. they didn't do that. perhaps they did have other people on the airplane with them, they willfully made this course deviation and when we look at, well, who's suspicious, the mere act of taking and traveling with false passports certainly makes those people suspicious. >> okay. what about the fake or stolen passports? nobody is saying anything about it. could the plane have flown to iran? mary, could the plane have made it to the middle east, iran, specifically? >> well, you have to look at not only could it make it through all of the different air space and through the radars and all sorts of civil defense but also could it just physically have made it there. we do know that they didn't take on -- the pilot didn't ask for additional fuel before they took off so it's got a range of 7,250
