Another elderly gentleman, an architect from Williamsburg came by to express how stunned he was that the towers fell in the manner they did. But he said, anything can happen in those circumstances, considering the impacts, that no one can predict or possibly explain. I agreed with his general conjecture, to a point. I said there's a lot we would like to explain and some that we can't. I could tell that he had had some doubts but had convinced himself by means of the 'chaos' theory, that all was well. That is, certain things, like impacts of this nature, can foment unpredictable results. I was trying to point out the many characteristics similar to controlled demolition (our talking points). He looked behind me and said, "now that's controlled demolition." He was referring to the video of wtc7 collapsing alongside an actual demolition that we had running in back. I said, we think so, that's world-trade 7. He was taken aback. He said, "they took that one down", I replied, "no planes hit that one." As it dawned on him what he was looking at, why we paired it with the demolition demo and yet another inconsistency that seemed to have been withheld from him in this incredulous tale, his jaw dropped. He turned without saying another word and walked away. Was he unprepared to face the truth?
