Well right or wrong, sorry to say the pentagon hit does not resemble a strike by an aircraft. To me it looks more like demolition work.
If you look at the attached concept impact drawing, the left wing would have sheared off, especailly hitting a renforced structure, while the right wing would have folded back and under the aircraft. With the impact at the angle sugested, we should see the left wing still on the front lawn or mangled at the base of the building. (which would be hard to see with the speed of the impact)
Also, if you look at the pictures taken from the security camera that "shows the plane impact and explosion". You will notice that the fireball and blast goes upward, but now outward and back opposite the dirrection of impact. This defies physics as there should be an outward blast. (now it could be that there just isn't a decent angle of the photos, vids, etc to show this, but there is not much in the way of debris outward either. (see my crappy drawing). "Every action has an equal and opposite reaction"
Now the other side of the coin is strange things happen in accidnts/events of this nature. I have seen pictures of cars travling at 150mph that hit a solid concreate wall and virtually disintigrated into nothing, leaving you says "hey where is the car?"
Also the theroy of a missle strike doesn't really pan out either unless it was a sea based missle launch. And one of ours! And that is a possibility if a cruise missle was launched to take out a hijacked plane, malfunctioned and hit the pentagon instead. Possible, but not very probable. Else we would have heard something about it.
The only thing for me, other than what I have stated here, that brings flight 77 into question, is that I don't recall any interviews with family memebers of the people who died on that flight. I remember lots of them from the planes that hit the WTC, and the one that went down in PA, but nothing of the pentagon hit.
