Yes.
It's well known that the strength of steel decreases significantly when it is heated.
It got very very hot for a significant length of time.
Why do buildings go "straight down" when demolished by expert explosives? Because of gravity. The collapse is not because of explosives, but
because of gravity.
And when the internal support columns are all evenly heated past their load limits, as would happen in a huge, intense fire, the same thing would
happen. Remember, there is also "dynamic" loading, as in when one part collapses the weight hits the other part, which now collapses from the
instantaneous shock because it also is barely at its load limit thanks to the fire.
People seem to think that they would "fall over" in one direction or another naturally.
Why? They go straight down because there's no reason to go any other direction.
Special effects in movies are designed to look cool, not be scientifically accurate.
They were built so that the forces are 'straight down' so that they could stay up. They weigh about the same everywhere in their cross section.
They're very heavy and from a long way away you can't see any random side to side fluctuation during the collapse.
It's just physics.
If large buildings caught on fire so violently we'd see it happening more often, but fortunately it doesn't.
Silverstein was a commercial investor who wanted to make money on his buildings with rents. There's no way the collapse and insurance payoffs on this
is anywhere near as profitable as if it had continued as a commercial concern. He'd be getting rents for four years on now, and he'd still have the
building.
