Reply #31: It really was fire alone that produced this collapse ?!

[Carefulplease]

Edited to fix unit (gallons instead of tons)

You don't tell me!

And the perimeter steel structure was a "curtain wall"? You mean, this was an open plan floor design with the non-core structural columns pushed on the perimeter just like the WTC? You don't tell me!

It burned for 23 hours, but floors started to progressively collapse after about two and a half hour, didn't they? And the Windsor Tower wasn't even hit by a 150 tons aircraft delivering half a ton of TNT worth of kinetic energy and thousands of gallons of fuel to ignite huge fires instantly on half a dozen floors?

The sprinkler system wasn't operational? Just like the WTC's whose main pipes were taken out by the impacting aircrafts? You don't tell me!

Did not the "extensive renovation" involve the addition of fireproofing to the structural steel elements? Are you arguing that the possible addition of some such material really contributed to the collapse? You don't tell me!
