Also broken windows and apparent lack of damage isnt neccesarily a factor of evidence there, the pentagon is the modern equivalent to a caslte, its doubtful they are using normal glass in the windows, it will be armoured glass at least an inch thick i would imagine, the kind of stuff an RPG would have a hard time against.
I have several things to say about this. I was working as a sub-contractor at the Pentagon several years prior to 9/11 - we were moving people out to swing space in preparation for the renovation. In fact, the plane struck the newly-renovated portion of the Pentagon (people had just begun to move back into), so the windows and walls were very reinforced; designed to protect against an attack. The windows were blast-resistant, to prevent injuries from flying shattered glass, and the walls were thicker and stronger than the un-renovated portions.
Secondly, if I remember correctly, the plane was estimated to be traveling at 500 miles per hour at the time of impact. At that speed, how accurately could people really say what they were seeing? Have you ever stood by a racetrack and watched a car go by at 120 mph? Multiply that by a factor of almost 5, and tell me how many details you could pick out. Also, what do expect to be left of the plane at that speed? What utter devastation would come from an impact of that magnitude, especially into a fortified building?
Thirdly, I have friends who are a pilot and flight attendant for that airline, and they knew the pilot and attendants on that plane. It was a devastating time for them, as well as for the families and friends of all the other victims. Are you truly going to tell me the government did something with that plane and all the people on it? Where did they take it? What did they do with the people? I worked with someone who was killed at the Pentagon that day; in light of the other horrible events that occurred on that day, I have to believe that her death, like those of all the other innocent people, was the result of the terrorists' actions.
There have been conspiracy theories about many tragic events in our history - think of Kennedy's assassination, and there are people who claim the Holocaust never happened - giving credence to these stories only increases the pain and suffering of the survivors, in my opinion.
Very well put, Sari.
