almost as funny
as your wacko claim the Twin Towers melted because Boeing 767 carried several hundred thousand gallons of jet fuel...the rational
minded truth is that fuel did not melt beams and B767 has max fuel approx. 23,000 gal ...and nowhere even near that on the day.
The tensile strength of structural steel is around 70-80,000 psi at room temp, and about 10,000 psi at red heat ~1300-1350°F. Melting was unecessary; with so much strength lost from the fire & impact damage, it's surprising they stayed up as long as they did.
How do you think a blacksmith works steel with just a hammer? By heating it up red hot first.
