If it was really the plane they said it was that hit the Pentagon, Bill, there shouldn't be any problem with releasing the video footage that was taken by the security cameras at the hotel across the street from the Pentagon, and which were confiscated by the FBI, so everyone can see for themself. This would end the speculation.

On the other hand, there are also eyewitnesses who say when they got to the crash site immediately following the 'crash', they could not see any sign of an airplane having crashed into the building.

* Contributor to 9/11 and American Empire: Intellectuals Speak Out 8/23/06: Account of Lt. Col. Karen Kwiatkowski, Pentagon employee and eyewitness to the events at the Pentagon on 9/11. "I believe the Commission failed to deeply examine the topic at hand, failed to apply scientific rigor to its assessment of events leading up to and including 9/11, failed to produce a believable and unbiased summary of what happened, failed to fully examine why it happened, and even failed to include a set of unanswered questions for future research. ...

It is as a scientist that I have the most trouble with the official government conspiracy theory, mainly because it does not satisfy the rules of probability or physics. The collapses of the World Trade Center buildings clearly violate the laws of probability and physics. ...

There was a dearth of visible debris on the relatively unmarked [Pentagon] lawn, where I stood only minutes after the impact. Beyond this strange absence of airliner debris, there was no sign of the kind of damage to the Pentagon structure one would expect from the impact of a large airliner. This visible evidence or lack thereof may also have been apparent to the secretary of defense [Donald Rumsfeld], who in an unfortunate slip of the tongue referred to the aircraft that slammed into the Pentagon as a "missile". ...

I saw nothing of significance at the point of impact - no airplane metal or cargo debris was blowing on the lawn in front of the damaged building as smoke billowed from within the Pentagon. ... all of us staring at the Pentagon that morning were indeed looking for such debris, but what we expected to see was not evident.

The same is true with regard to the kind of damage we expected. ... But I did not see this kind of damage. Rather, the facade had a rather small hole, no larger than 20 feet in diameter. Although this facade later collapsed, it remained standing for 30 or 40 minutes, with the roof line remaining relatively straight.

The scene, in short, was not what I would have expected from a strike by a large jetliner. It was, however, exactly what one would expect if a missile had struck the Pentagon. ...

More information is certainly needed regarding the events of 9/11 and the events leading up to that terrible day."
