I believe it was aliens that did it. They were pissed off because of Roswell shootdown and after traveling some lightyears it was payback time.
2 planes were crashed into WTC by telepathy hypnosis and 1 laser beam at Pentagon. Last plane was abducted into a space-ship but the government shot down the space-ship. To cover it, again, Bush blamed Osama. The reason he is not caught, is that Bush IS Osama... the perfect cover, and it can be used over and over again
