Can Explosives Really Make a Building Fall Faster Than Physics Allows?

[beardad]

A fellow I work with claims that the world trade center buildings and building # 7 fell faster than physics will allow. He thinks that explosive charges placed in the buildings caused the buildings to fall faster than terminal velosity? I think he is a quack. how can I show him he is a quack. or is he right? thanks for your time

And your friend is wrong. Explosives placed in the building would not cause it to fall faster. The explosions simply undermine the structure, which then collapses under its own weight.
