You will see that iron undergoes a phase change at 600C, becoming
soft and pliable. It is this phase change that allows farriers and
swordsmiths to shape iron in a controlled manner. Steel changes from
the solid metal it is at room temperature, to a material with a
consistency and structural integrity about the same as well-chewed gum.
And, of course, it doesn't matter how much fuel there was. They
could have FILLED every floor of building with a couple of feet of
Jet A and replaced the air with pure oxygen, and it still couldn't
possibly burn hot enough to bring the buildings down.
If you accept that the fuel burns above 600C as you have above, you
*have* to accept that the structural integrity of the floors where
the fuel fires were was fatally compromised by the heat, as the Fe
phase diagram shows.
So: "Sorry. Bullshit.", to coin a phrase.
We don't know what the hell happened on 9/11. The administration's
"just-so story" is no better or worse than the conspiracy
theorists': they're all wild-ass guesses based on too little
information and too many jumped conclusions.
Or possibly based on some school-level physical chemistry.
