Quote from 377OHMS:
I had a 300 level Materials Science class and a 400 level Materials Science class and a fair amount of electrophysics work on conductor lattices while getting a BSEE. Doesn't make me an expert but it does allow me to say that yes, I do have a technical background in materials science.
I don't hide the fact that I made crude thermite when I was a kid. Its just ridiculously simple ingredients. The magic is getting it lit which requires immense amounts of heat. I suppose with all the fuel that there was enough heat to get some aluminum burning and start some thermite-like metallic fires. I remember seeing some molten metal dripping/falling off one corner of one of the towers before the collapse. I can imagine that the extreme violence of the collapse, extreme enough to grind desks and chairs and office equipement into dust, might spread around remnants of the metallic fires somewhat homogenously in the debris and give people ideas.
You see an airliner full of fuel hit the tower and then claim it was blown with explosives? I just don't see why folks go there.
