Prior to making the post, I had been watching a TV documentary on the Discovery Channel of the Loizeau family and their work. controlled-demolition.com And, indeed, the documentary was relevant because it explained in detail many aspects of the actual demolition. Interestingly, the Loizeaus were employed to clear the remains of the Murrah building and the TV documentary showed how they did it. The first phenomenon found in a controlled demolition is the enormous amount of pyroclastic dust produced and which arises from the actual burning of the concrete and the reinforcing steel by the explosive charges. This pyroclastic dust is quite distinct from the smoke produced by substances which burn at lower temperatures, eg kerosene.911research.wtc7.net >>dust clouds, exhibiting the behavior of pyroclastic flows associated with volcanoes, rapidly grew as they fell. Each cloud consumed its tower's top in a few seconds, then continued to descend, remaining centered around on the tower's axis<< The second unique phenomenon is the creation of "squibs" which arise from the charges as the explode in sequence. I then did a search on "squib" and came up with the links which I posted. Interestingly enough, the squibs turned out to be the small, sequenced explosions ("puffs") which I had previously tried to draw peoples' attention to on this thread and which can be seen clearly only in certain views of WTC1 (North Tower). Like you, I am satisfied that the above, plus the aspects which you mentioned, prove that a controlled demolition took place.
