I'm not going to read the comments on this one, just going to inject a personal note. I was a corporate travel agent in September 2001, and I put a client on the plane that hit the Pentagon. She was real, the plane I put her on was real, the eyewitnesses I am acquainted with are real, the flight manifests that I saw were accurate, and her orphaned son is sure as hell real.

Sore subject.

I only clicked one box, because honestly, some stuff (like the whole "was Osama on the CIA payroll?" thing) is plausible but unproven to my satisfaction.
