the collapse was predicted, you know that
Ok. I was referring to the decision to evacuate the building, create a perimeter, and let it burn itself out. I believe, from the quotes I've cited, that they were not sure at that time whether WTC7 would collapse or not.
Deputy Chief Peter Hayden
Division 1 - 33 years
...also we were pretty sure that 7 World Trade Center would collapse. Early on, we saw a bulge in the southwest corner between floors 10 and 13, and we had put a transit on that and we were pretty sure she was going to collapse. You actually could see there was a visible bulge, it ran up about three floors. It came down about 5 o’clock in the afternoon, but by about 2 o’clock in the afternoon we realized this thing was going to collapse.
After the BBC Conspiracy Files episode on WTC 7, which ironically you made a brief appearance on, things became a whole lot clearer. In that program, FDNY Chief Peter Hayden made this statement:
"We were concerned of the possibility of collapse of the building. And we had a discussion with one particular engineer there, and we asked him, if we allowed it to burn could we anticipate a collapse, and if so, how soon? And it turned out that he was pretty much right on the money, that he said, ‘In its current state, you have about five hours.'
Peter Hayden is quoted yet again on this "engineer" fellow in this 2013 court document: http://www.ca2.uscourts.gov/decisio...3c33b98-9cbf-4b82-b557-6088e207c8f6/1/hilite/
"Chief of Department Peter Hayden consulted with an engineer:
We posed to him the question that considering the structural damage that was obvious to the – to the building on the southwest corner, and the amount of fire damage that was occurring within the building, could we anticipate a collapse and if so, when. He said yes and he gave an approximate time of five to six hours, which was pretty much right on the money because the building collapsed about 5 o’clock that afternoon.
So, if his recollection can be trusted, at some point, from his own observations and the conversation with the unnamed engineer, Hayden anticipated the building collapsing.
So the points leading up to this were:
• WTC 1 and 2 setting precedents by collapsing
• observations (damage, bulging, noises etc.)
• alleged expert opinion
The thread is now on the border of well-trodden truther territory, so let's recap your question quickly before the thread crashes and burns:
1) Who was the very first person on 9/11 to suggest the idea that WTC 7 might collapse
2) What was their exact reasoning?
1) who cares? the "idea" was certainly part of the decision to evacuate the building, as evidenced by the quoted reasons pertaining to it being unstable.
2) reasoning for the "idea" has been quoted, and it's plausible that this idea moved up from possibility to anticipation during the afternoon, as the building deteriorated further, more information was collected, and experts were consulted.
