I'd probably believe this Flash presentation if someone could tell me where AA Flt 77 ended up on 9-11 (assuming it didn't crash into the Pentagon according to the "evidence" in the Flash presentation), what island the passengers and crew are all living on, and how much the gov't paid all of them to never talk to friends and family again.
Flt 77 took off from Dulles that morning, passengers on the flight (including Barbara Olsen, wife of US Solicitor General Ted Olsen) made cell phone and Airfone calls to loved ones saying that their plane had been hi-jacked. This is consistent with the stories surrounding AA 11, UAL 175, and UAL 93, which were also hijacked that same morning and crashed into buildings (or with the assumed intent to crash into buildings). And look how many people saw the planes crash into the WTC towers with their own eyes.
When AA 77 hit the Pentagon, that Boeing 757 was going so fast, hit the building so hard (there is plausible speculation that the wings folded against the hull of the aircraft), and was carrying enough fuel to start a fire hot enough to liquify most of the aircraft.
There aren't many air disasters on record where a plane has been intact when it's struck land or an object at 400+ mph; and in those rare instances, there isn't much left of a plane. The pictures of charred airplane hulls in that presentation are of accidents that occured on take-offs or approaches where the aircraft was travelling in the 100-200 mph range and glanced off the ground, as opposed to striking a brick wall at 400+ mph.
Long story short, just tell me the fate of AA Flt. 77 and then I'll bite into the conspiracy theory.
