Here's a corollary to that one: Softened steel will not carry as

Bullshit detector going crazy!!! There was no softened steel.

Steel looses half its strength at 600C degree.

There is
NOTHING you can post here to explain how fire in the WTC softened ANY
steel.  Pure conjecture that is just another meaningless distraction.
Burning jet fuel is hotter than a forced air mixture of oxygen and
acetylene too, I guess.

Do you believe there is a temperature significantly lower than
600C such that stuff (fuel, furnitures, carpeting, etc.) stop
burning when it is reached?
