re: Newly released 9/11 footage of Pentagon: Airliner or missile?

Atta had his pilots license before they even began plotting the attack. As far as the others, I'm not a pilot, but I suspect that crashing the plane is not all that difficult. Hani Hanjour, the pilot of AA 77, had an FAA commercial pilot certificate with a satisfactory rating so he had to be somewhat proficient. In any case, it's a stretch to refer to them as untrained.
