Yes they were hot. I explained why. FDNY reached the bottom of the fire. Hot air rises. The heat above them was magnitudes higher. And of course they would say they could put it out in the moment. That's why they do. But in reality they were seeing a small portion of the problem.AggiEE said:double aught said:Quote:
They literally can't collapse from fire that burns significantly lower than the point where steel weakens and do so across the entire building despite fires localized at the lightest part of the building.
There would be no point in the painstaking detail and effort that goes into a controlled demolition if all it took to level a building largely symmetrically was office fires
Those fires were ridiculously hot. I don't know why you think otherwise. Modern office furnishings are synthetic and burn much hotter than traditional furnishings. Plus jet fuel. Plus minimal compartmentalization (which slows fire spread) due both to the design of the buildings and the damage they sustained upon impact. You are not giving those infernos the respect they deserve.
And steel fails in building fires all the time. The steel roof trusses in strip centers can collapse rather quickly if fire isn't gotten under control. You're right that it's extremely rare in high rises, but this was a pretty unique day.
They were not "ridiculously" hot. The fire department reached the impact zone and was confident they could contain the fires.
The temperature jet fuel burns at are nowhere close to weaken the ENTIRE core structure around or below it
And I didn't say the jet fuel weakened the steel. But it did serve as maybe the most kindling ever. It helped ignite an enormous amount of contents. Lighter fluid doesn't cook your steak. But pour enough on the coals and that fire will get going faster and hotter.
