Do you have a rough idea about how much molten steel that would have produced? Would be identical to the mass of 1/3 of the core columns up to the 88th floor.
Then add to that twice that mass as thermite, as it would take that much to do the actual melting. You should even show that filling the columns with twice their mass in thermite would not overload them statically already.
Once you take out 1/3 of the core columns in the basement, these columns rest on nothing. As soon as the portion of dynamic load created by the beginning collapse at the top propagated through the remaining columns to the basement, we would have observed a classical from-the-bottom-collapse in addition to the top-down collapse.
Any fireproofing formerly attached to now molten steel would have separated from said steel, disintegrated to dust, and would not have been found as such. The glassy texture fireproofing you talk about was remnants still attached to never-melted steel.
Instead, huge amounts of formerly molten steel that would have posed enormous challenges to the clean-up crews.
I would have to do a quick research, but I am fairly certain that close to 100% of the core columns were accounted for. 0% of them showed signs of melting.
Nice James-Bondy ideas there, Bill!
Just where is your proof?
(If I can place a bet, I would bet that some version of "all evidence has been shipped to China" is on my way
