Stop making vague conspiracy jibes, and either find one factual error in the following paragraph, or leave it in:

The main impact zone of the crash was approximately 19 metres (57 feet) in width. No wreckage was found in the immediate impact zone at the front of the pentagon. The lawn in front of the building was unmarked. Within the main impact zone was a hole that the object punched in the building, approximately 9 metres (27 feet) in width. The Pentagon is composed of five concentric rings. Only the outer three rings were penetrated during the impact. The upper floors of the first ring collapsed, but those of the second and third remained intact. At the end of the third ring was a circular 'punch out' hole, again 9 metres (27 feet) in diameter. The wingspan of a Boeing 757 is 38 metres (114 feet).
