I don't doubt that the impact and fires would have caused the collapse
of the towers but there is one bit that I have never understood.

I would have anticipated that the supports on one side of the building
would have failed, causing the tower to twist and fall sideways. Maybe
one side would collapse dragging the other side towards it. I would
never had anticipated that a building would pancake straight down into
it's own footprint, as all 3 did.


AIUI, most of the vertical load-bearing in the towers was through the
central core, so punching a big hole in the side or in one corner
isn't going to matter much.


Not sure that was true..however one reason no one gout out above the
fire, was that all the core was also on fire and destroyed.

And its where all the lifts and stairs were.

So it doesn't make a lot of difference.

No steel building is designed to withstand a fire. Its designed to delay
structural damage to allow people to get out, and firefighters time to
get the fire under control.

In this case it was so extensive a fire that people could not get out,
no could the fire be brought under control.
