On the other hand, I am a structural engineer.
I have seen buildings set up for controlled demolition. The interiors are completely gutted, explosives are packaged on the naked structural beams, and the interior is a forest of detonation cables.
None of this was true of the WTC or any of the neighboring buildings.
I've also had it up to my eyeballs with the "fire doesn't melt steel" gag. You don't have to melt the steel. First year engineering students are taught about how structural steel loses strength as surprisingly low temperatures, which is why all steel buildings have insulation sprayed on the members.
