I am an electronics engineer

I am an electronics engineer by training. In first year I learned general engineering topics like strength of materials, mechanical engineering science, mechanics of solids and engineering physics.

This puts me in a position to understand what calculations and assumptions are more valid, if not directly by reading the papers, then by reading critiques and articles on them. As such, though I have not read too many adjunct papers, I have read the NIST reports in the relevant parts.

In my case I am absolutely sure about the general accuracy of the mechanism given by NIST for the collapses.

Beyond that questions like who was behind the attacks is not something I have investigated thoroughly because I have not found a compelling reason to do so.
