3. You do not take into account any of the heat produce by exploding transformers ( when the loads are shorted by arircaft slicing through, or floors collapsing) or any other source.

Not at all. I'm just seeing some problems with your hypothesis that aluminum power from the airplanes could have explained all of the heat related damage that was done to structural steel in all three buildings. Unless that wasn't what you were saying, in which case, I stand corrected.
