Killtown's page Introducing the amazing new Penta-Lawn 2000! (found here) is just another of many half-truths (disinformation) regarding the crash at the Pentagon.
Killtown presents photos such as the following:
to convince the reader that the aircraft did not hit the ground before it hit the Pentagon wall. However, the pictures he shows you, have been specially selected. Other photos (for example, those below) show that the truth of the matter, is somewhat different. These photos show that there was a large fire close in to the Pentagon wall. So, where did the fuel for the fire come from. We already know that for the aircraft to strike the wall at the first floor slab with its right wing, as it did, the left wing engine had to be below ground level. That is, we know the the left engine struck the ground, just before the plane entered the building. One concludes that the left wing broke apart and emptied jet-fuel along the wall, where it ignited.
Note that in the aerial shot you can see where jet-fuel has run down a shallow ditch and burnt the grass. The shallow ditch is a pre-9/11 feature and is visible in this pre-9/11 satellite image. It is also visible in the top right hand photo, where it appears to be filled with water from the firefighting operations. The above aerial shot was taken from this video clip.
