must be so
a real firefighter would know, fires not fought can lead to collapse of the structure!
examples must be in the thousands
I see you guys have resorted to personal attacks in the form of unfounded lies that can be definitively disproved. I already displayed the documentation on being a firefighter.
Here are some actual statistics for you (done prior to Madrid which did not suffer total collapse and was not primarily steel. Please don't compare Madrid fire involvement which was fully involved with WTC 7.):
I have taken the time to highlight a couple for you. You do the math. Of the 3 purely steel frame construction buildings that had TOTAL collapse every one of them was at WTC - WTC 1, WTC 2, WTC 7. All the buildings where the appearance of explosives was related to us by over 40 firefighters.

Probably just another 9/11 "coincidence".
Please read these reports for the actual details. Try and find another steel frame building over 20 floors made purely of structural steel that suffered total collapse. Or for that matter ANY total collapse of ANY building made of steel except at the WTC.

You can't argue with these scientific studies and comprehensive studies of all significant collapses in history.
Purely steel - Total collapse = 3.
To see the other fires that only caused beams to fall, major damage to floors or significant structural damage, go here.

That will be all until you deal with the science of the drafting of smoke on the leeward side of a building and/or show ANY photo or video of substantial fires in WTC 7.
