What about the molten red-hot slag seen pouring out of the building in some footage? Or the fact that they found molten steel in the wreckage? Thay speaks to the steel actually melting, not just softening.
And thats pure aluminum. Plenty of alloys have lower melting points.
I've seen molten aluminum in junior high school metal shop. It is mostly a silver color with some red highlights. But helenofthewest said steel was found, not "metal." Shouldn't you close the loop on that?
Molten aluminum would bring another actor into the play: combustion of aluminum vapor. The adiabatic flame temperature of aluminum burning in oxygen is 3,732 C (6,750 F). Combustion of aluminum would leave aluminum oxide ash...which can easily be misidentified as residue of "thermite." (Yeah, yeah. Aluminum's boiling point is a lot higher, but the aluminum does not have to boil in order to have a vapor pressure. Puddles of water on the sidewalk eventually evaporate at ambient temperature without boiling. Same principle.) Aluminum is the main fuel component of large solid rocket motors.
Molten aluminum would have a vapor pressure, but less than atmospheric. Just as liquid water also has a vapor pressure, but less than atmospheric. Only when the vapor pressure equals atmospheric pressure do we call that temperature the boiling point. Thermite would leave nothing behind that is not already provided by the fire environment hotter than molten steel and combustion of aluminum with available oxygen. The failure to recognize this fact is what clues me to the incompetence of the supposed "truther" analysis.
