Where did the engines go thoughThere is video from parking lot cameras, but it's tough to see much. I have friends that that were a the pentagon at the time of the incident. A plane hit the building.
Also, are you claiming that the planes in NY are real, the plane that went down was real, but the pentagon was faked? Does that make sense to you?
The plane didn't disappear. It hit multiple layers of reinforcement concrete at high speed and disintegrated, just like planes that hit the ocean at high speed and steep angles.
The conspiracy isn't that the government planned 9/11, the real question is were they just incompetent and didn't see the obvious clues of the plan or did they let the attack occur to justify war? GW was completely floundering prior to that moment.
