I have no use for 9-11 conspiracy theorists. Period. It takes a particularly diseased mind to blame multi-level government conspiracy for deeds claimed by our enemies as their own action on the US.
However, I found this to be terrifically interesting: an astonishingly well-done video of the crash into the Pentagon of AA Flt. 77.
(My first YouTube embedded movie!)
This will not influence those who want to Blame America First, but is an excellent coverage of the crash, and an explanation of some minor details.
