Nice job! Thanks.

Guiliani says he was told minutes before the collapse that the building would collapse

From youtube autotranscript, [ed. ] by me:

I went down to the scene and we set up headquarters 75 Barclay Street which was
1:44right there with the police commissioner the fire commissioner (they had [ed. the head of]) emergency
1:47management
1:48and we're operating out of there when we were told that
1:51the World Trade Center was gonna collapse and it (it collapsed [ed. did collapse]).
1:54before we can actually get out of the building so we were trapped in the
1:57building for (it's just a minute [ed. ten fifteen minutes])
1:59finally found at Exit got out walk north
2:03took a lot of people with
2:07headquarters into which you put enormous

IMO, they certainly didn't know up front that the building would collapse, as they wouldn't have gone to 75 Barclay if they had. Minutes before the collapse, they were told it was going to collapse. I'm guessing that this was figured out using some of their observations of the fire, seeing how the fire was playing out, and then realizing that the building would collapse. Nobody knew up front. Guiliani didn't know. The lead structural engineer didn't know. Not even Bin Laden knew, "the most optimistic of them all".

Thanks again.
