A big jet is a complex piece of machinery if you are doing take-offs and landings. But you could learn to "steer" one in a couple of hours if you understood the principals behind what you were doing.
But to learn this requires a big jet to practice on and it's unlikely that anyone short of a national government would have access to one.
Osama bin Laden may have been the one who carried out the hijackings and crashes, but he had to have backing from higher up. I'd guess Iraq.
Flattop, sorry about the weak verb. I do agree with you about the draft, tho. Where does it end? Good question. But if we don't answer this act of terrorism against our nation strongly, it will only be the first of many.
It may be the first of many anyway but we have to do something. If we let it slide...
