Different scenario.
First the steel of the Columbia didn't "catch fire" . Steel is fire proof.
The steel of the Columbia did fail from heat on reentry.
I don't know if you understand the concept of a bellows or how there may be a wee bit of difference between a static enviroment and one involving motion.
You are right.
Hot steel is weaker than cold steel however the steel in the towers was rated to maintain sufficient strength to support the structure even considering the temperatures which could have possibly been generated by the fires of 9-11 .
As far as the aircraft (aluminum) impacting the structural steel columns.., have you ever played Rock , Paper ,Scissors?
They couldn't find any validitiy to them.
Even Fox news reported on the "dancing Isreali Mossad agents".
Popular Science "couldn't find any validity" to any of the alternative theories?
Not one alternative theory holds any inkling of Truth and the Official , the Mainstream theory, is completely true and complete.
Is that what you believe?l

I asked the questions because some have asserted that it fell at freefall/near freefall acceleration. I say that it is critical to be more specific - to say how fast it did accelerate, and how fast it should have. Without that, then to say it fell too fast shows ignorance. So, have it if you can.

Steel doesn't catch fire . It is by nature "fire proof" . That being said steel is a Most Excellent conductor of heat.
" Fireproofing" of steel is kinda of a misnomer.
The "fireproofing" is meant to keep the steel from transfering high temperature to adjacent combustible materials.
You FAIL !

You're right. The reason for the thermal protection system on the Space Shuttle was to keep the astronauts comfortable. Heat buildup had nothing to do with the failure of the Columbia upon reentry. No shuttle had ever just burned up and disintegrated on reentry before. It made it all the way to Texas! A bomb must have blown it up. Or a missile fired by Jackie Martling because he thought Howard Stern was on board.
