Dick Cheney and the rest of 'the Vulcans' were all in it up to their eyeballs. They were aided by Mossad, too.

But on the other point, I have to disagree. As far as I see it, there are three alternative theorys about what happened to the aircraft: Electronic hijacking, drone swap, and no plane theory.

I just finished writing a paper examining all three of these theorys, and have concluded that drone swap was the most likely method to have been used. It is the theory that best accounts for all the anomolys of that day.
