I heard otherwise, but if I recall correctly, they still fell in a way that looks utterly implausible.
May I suggest watching the video of the Chinese demolishing an entire ghost city of tower buildings. Since there is no one in the city, they did not bother with the "make the building fall into its own footprint" technique. Instead, they just blow up the base of the building.
Do the buildings fall down straight into their own footprint? No, they keel over sideways. That's what you expect frankly. They may fall at free fall, but not while also destroying the building. The rest of the building is fine until it hits the ground.
I analyzed the fall of WTC7 because, again, at free fall, which is the asymptotic limit, the analysis becomes simple. The other buildings do not seem to have fallen at free fall, so it is harder to show they had explosives in them. I still think they did, but the argument is much harder to make.
