"The point in bold is the one that has always made me wonder, and as you mention, the one that was never been explained.
Specifically, the plane was travelling east, turned around and went west, and instead of dive bombing into the pentagon or smashing into the eastern side, made another 180 degree turn and proceeded to skim along the ground (something next to impossible for a jumbo jet to do, especially piloted by the inexperienced hijackers) and crash directly into the western side. This side was, incidentally, the side that had been evacuated and reinforced. Strange."

You seem to be very with it, i like your response a lot. though i have to ask, link?
