There was a high wind during the 911 attack. The steel would only have to heat to the point where the shear and tensile strength would not be capable of holding up the floors. It doesn’t have to melt at all.

That temperature is much lower than melting point.

There’s a vid of a blacksmith on Uboob getting all up in Rosie O’Donnel’s grill about her ass statement of fire not able to melt steel. The smithy took some 1/4 x 2” steel flat bar to 1600F which is substantially below structural steel melting point. His point was to show steel’s properties needed to support most anything pretty much turn to mud at that temp. The heated bar was in a vise, and the smithy was able to flop that bar 90 degrees back and forth merely using one finger to do so.

That was part of my question.

I never mentioned melting.
