- What engineering and physics allowed WTC 1 and 2 to fall in near-free fall when only a few stories were damaged by the planes?

- What caused the structural failure of the support columns of WTC 1 and 2 to allow the pancaking of both towers?

These are straight up engineering questions that are not answered by the official NIST reports. For the first, the University of Alaska did a years-long study debunking the official story. Links provided.
