What about the attack on the Pentagon? Was it really a plane that hit it, or something else, maybe a missle?

Why did the FBI go around and confiscate camera footage from the surrounding buildings not releasing them to the public when they clearly showed us the planes that hit the trade towers?

Why was the only footage released to the public from one of the most heavily guarded places in the world low quality footage showing only five frames at about one frame per second?

The U.S. Secretary of Defense Donald Rumsfeld admitted the day before the attack that the Pentagon was missing 2.3 trillion dollars. Could this attack on the Pentagon have anything to do with covering up that information?
