In reply to the discussion: Fire Breaks Out on 88th Floor of 1 WTC [View all]AtheistCrusader
(33,982 posts)WTC 1 and 2 were hit with aircraft travelling at 500+ mph, in excess of ~300,000lbs, full of fuel, and lit, again, multiple floors on fire across 1 acre areas, imparting ~7.4 million foot-tons of torque on each of the buildings at impact.
WTC7 was hit with burning debris from tower 1, some structural damage, but nothing like WTC 1 and 2 experienced, and simultaneously lost all water pressure as the collapse of 1 & 2 cut the local water mains. WTC7 failed entirely due to fire, and it took several hours longer to do so, than the steel framed components of the Windsor Tower fire.
The issues with WTC1 & 2 are not directly comparable to 7, because your starting point with the fires is already so far behind the curve, with structural members already removed by the physical impacts. Typically the 'hurf durf fire steel building' references are directed at WTC7, and this is what I was responding to. Towers 1 & 2 initated progressive collapse at the points they were physically impacted by aircraft for a reason. Had there ONLY been widespread fires in towers 1 & 2, they would have stood much longer, like WTC 7 did.
I'm glad this is just a big stupid fucking joke to you.
