Here is the key photo of the Pentagon -- after the impact -- but before the collapse.
This photo should have received a lot of attention -- but I never saw it cited.
You can see the hole is much larger than we were led to believe. It is certainly large enough to accommodate a Boeing 757.
The plane hit the Pentagon at first floor level --
I have generally stayed out of the "what hit the Pentagon" debate -- because it is so contentious. IMO there is no doubt about the answer. It was flight 77.
The controversy has diverted people from the really important question, which is: who was flying the plane?
It certainly was not Hani Hanjour. The man was a flunky.
