(1,443 posts)32. Hard to believe
steel can lose its strength to the point of complete failure after burning for a couple of hours.
if that were the case then all of our steel pots and pans would be completely useless for cooking.
The Twin Towers were a giant heatsink. The heat would be absorbed and dissipated by all 110 floors of steel framing before it could do much damage to any part of it. It doesn't just simply get hotter and hotter at one point or one floor of the building, because the heat is dissipated throughout the massive structure. Which makes it impossible for fire to weaken any of the steel to the point of catastrophic failure.

WTC7 straddled the con-edison substation. Have you ever heard an electrical transformer blow?

Your first sentence is true. However, it bears no relation to the WTC impacts/fires.

The mass sitting above the fire on the South Tower was equal to the Yamato.
