What's even more suspicious about it is that even if the passport did somehow miraculously survive and miraculously land where it could be found, despite a whole fucking building landing on top of it, and if someone did find a passport in the rubble, what are the odds that despite all the chaos someone would run a check and discover that it belonged to someone on the plane and also know conclusively that this man was one of the hijackers. Absolutely bizarre and lends credence to a lot of conspiracy theories.
