This thread isn't looking for what initiated collapse, or what transfer trusses and core columns were doing.
We are asking if there's any way controlled demolition caused the east part of the perimeter frame to fall over at it's onset.
We know the perimeter frame was standing in a visibly static position, then lurched over at the instant the west penthouse initiated it's descent. Does that look like controlled demolition? How could controlled demolition make the structure move like that?
