But the buildings started collapsing right at the impact. Check here at 5:55. You can clearly see the top collapsing and the building beneath the impact not moving one bit until the top collides with it.
Well, they were crashed into by jet airliners that blew holes through the building at the point of impact you are talking about. Massive fireball, burning for hours and all that. It is not implausible that that would affect the fall of the building.
You are assuming a few things.
I do not agree that the point of impact from the airplanes is necessarily a factor in the takedown. In fact, I think it is unlikely.
I do not believe that explosives were necessarily used, although I do think it is probable.
I do not believe a controlled demolition requires fragile components.
I do not believe that the takedown needed to occur in an exact spot that was ravaged by fire.
It is unclear to me how much time it would take to execute an emergency demolition if the protocol were pre-planned and practiced.

I just don't see any way to predict or pull this off without some magic.
