lumpur. thank you so much. one of the possibilities so many people are discussing, the possibility that this was some kind of a hijacking attempt. the question then would be, why have we not heard a word from the people behind who may have pulled this off? no chatter at all. it's been 11 days. no claim of responsibility, nothing from possible terrorist groups. so, the big question is, if this was a 9/11-style plot, why haven't we heard anything yet? why hasn't anything happened yet? >> what is the end game? why would they do this, if they are, in fact, doing it deliberately? why would they take an airplane full of passengers and roar around the skies and hide it or do whatever else they're doing underneath the radar? why would they do this? what did they want this for? now, what would happen if they did, in fact, find a way to land, refuel, take off again, and then threaten the integrity of certain kinds of structures,
