Erhm, we DO know about the deception by the Pentagon and DoD. The timeline and testimonies submitted by both, suggested that they were tracking AA77 and UA93 prior to their respective crashes, and that they were ready to intercept at least UA93. The reality, of course, was quite different. It was a major CYA move.

Yawn....almost as boring as the physics textbooks we used back in high school. And quite frankly, that was too many years ago for me to attempt to claim I am an expert in Physics like everybody in this thread seems to be.
1. I kept seeing the word ASSUME or a variation of it. Quite a few assumptions were made.
If we assume that the upper section comprising 16 storeys falls under a full gravitational acceleration through a height of one (removed) storey, a distance of 3.7 metres we can calculate that its velocity upon impact will be 8.52 metres per second and have a kinetic energy due to its mass and velocity of 2.105 GJ. (Using the figure of 58000 tonnes as detailed in the report by Bazant & Zhou.[1]) In reality there would be some losses of energy due to residual strength within the failing columns of the removed section, but these are ignored for the purposes of this analysis.
Those storey columns more distant from the impact would be of a larger cross section, requiring higher loads to cause full elastic deflection. Using only half of the maximum elastic deflection, 56mm (16 * 7 / 2), is, again, an assumption in favour of collapse continuation.

Speaking of honesty, you cite with approval 911Myths as a source. That's a website I've spotted rather a lot of dishonesty in - one example that leaps to mind is the whole straw-man approach to the issue of Atta's passport.
In other words, it's the hugest assumption that the passport was ever in the plane in the first place: there's absolutely no evidence to suggest it was

The one example that leaps to mind is Atta's passport huh? In what respect? That there are photocopies of it? Surely you are not going to claim that it was his passport that was found. Because that isnt on 911myths. Satam Al Suqami's was. And the "straw man" you seem to be referring to is that it is pointed out that paper/cardboard can and DOES survive aircraft accidents. So, if you think that pointing out that it is not strange for personal effects to survive disasters then so be it. Enjoy the warmth of the sand.
The owner of said passport was known to have been on the plane. Checked in by ticket agent, on the manifest and allowed to board by the gate agent.....both of whom identified Mr. Al Suqami. So why is that HUGE assumption?edit on 5-7-2011 by vipertech0596 because: added

Really helps separate the wheat from the chaff on here. I was trying to discern where you were coming from, and from your reply about labels, I must have hit pretty close to the mark.

Try reading the 9/11 Commission Report in its entirety. Then look into some of the released documents from the Commission and FBI.
