All concrete doesn't turn to dust, that claim is based opulls figures out of thin air to fit the conclusion n a paper that just
The conspiracists have always maintained that far more concrete was turned to dust than can be explained by the official story, i.e. it was due to explosives.[/url]
The figures are pulled of of thin air, the energy required to do what the conspiracists claim, would have required kilotons of explosive (which would have been a little obvious stacked up around the building), or a small nuclear bomb....
It also disproves the freefall claim since its obviously ahead of the wave of destruction.
And how did it get to be ahead of the wave of destruction? How did it become detached from the building if not by pressure from the falling debris?
It's part of the falling debris, therefore it's from above the point where the wave of destruction has reached. Hence, it has to have moved faster than the wave of destruction to getting to where it is, below the destroyed section of the building. Therefore, it has to be accelerating faster than the main part of the building. Unless it's got little rockets attached it's in freefall (allowing for air resistance, which wouldn't affect a substantial chunk of metal to any great extent). The rest of the building is moving slower than this and acclerating less rapidly, because of the resistance of the stucture beneath...yes, it offered resistance but not enough to prevent collapse.
Therefore, the building did not fall at (near) freefall speed, though detached panels separated from it did....
...How did they get separated at exactly the same length, or any of the hundreds of other column sections which all seem to have somehow broken at the same length, with such neatly squared off ends?
As I said the outer structure was made up of thousands of identical units, when the structure gave it would give at the weakest points - the joints between the units. So a lot of the falling pieces would be single units, or multiples of those units, and apparently the same size and squared off shapes. The girders would have been in standard sizes and they too would have tended to separate at the joints.
At a distance the debris looks very uniform, close up it's possible to see that a lot of it is bent, twisted and broken just as you'd expect.
