Shell, great post - I see you're skilled in reading upside-down book titles

Flight 93 - as you say, could've hit the Pentagon (from evidence, unlikely) and also could've landed at Cleveland (which is an ugly city on the horizon as you drive north through Ohio - but I should not digress).

Certainly the impact you'd expect from a 757 isn't there. Missile? Perhaps. The carpark 5-frames don't tell much. Having said that, a missile taking out 5 lampposts? Or rigged to go?
