This wasn't a public building, since it was our center of military and intelligence, why does it surpise folks that some of the video were confiscated?
Secondly, how many of these idiots that testified that, "it sounded like a missile" had actually ever heard wtf a missile sounded like?
Finally, most of the planes that were shown in the pictures were right before or after take/off landing or had an inflight problem where they had slowed down considerably. I would think if you were kamakazi'ing into a building you'd be punching the throttle.
It could be a conspiracy, or it could be a multitude of other things...
It was three years ago and I don't recall or not if the news was showing plane wreckage or not.
