<<He's right. The Jet fuel didn't melt the beams. It didn't even soften them. The fuel burned up too fast to affect the beams. What it DID do was provide the ignition to set the rest of the building on fire. Which burned at 1500 degrees. And THAT softened the beams so that the building could collapse.>>

Years ago I gave an old farm house to some rural fire departments to practice on. Light it up and run in and put the fire out. Over and over. I was down there watching it from 100 yards away. They did a small trash fire in a second story bedroom and were going in through the roof. I saw some smoke coming through the shingles on the far side of the roof and thought uhoh. The firemen also saw it and slid down the ladders. Whomph!! the house exploded and was so hot I had to turn my back.

That's when I learned the 1500 degree rule. The small fire gets to 1500 degrees and the whole building explodes. Not spreads from room to room but the whole building explodes.
