It had a burning skyscraper fall on top of it. That is generally bad for most buildings.

It was “pulled” (audio recording of him calling it) by Zionist WTC owner Larry Silverstein, with announcement of its destruction press release read on TV with WTC 7 visibly still standing in background image. Most experts believe the operation would need several days of preparation instead of the few hours that took place until a bit past 5pm the same day, and because of this, Silverstein’s $1B asbestos problem that 9/11 solved, could have provided a “backup solution” for the 2 main towers melting beams from jet fuel.
