I think we are saying the same thing. Either the hijackers missed their target on first approach, or the plan all along was to hit that specific side of the Pentagon. It just seems that if they were good enough pilots to pull off the turn and the level descent at high speeds, they could have done it from the West.
"In the beginning of a change the patriot is a scarce man, and brave, and hated and scorned. When his cause succeeds, the timid join him, for then it costs nothing to be a patriot."--Mark Twain
