Grenfell Blaze

Jet fuel did not create temperatures to cause a collapse. Jet fuel was completely burned in minutes. But it ignited many flammable materials inside - especially tons of paper. It also blew fire protective materials off steel beams.

Anybody can see how long and hot that fire was. Eventually, exposed beams melted. In the WTC 7 collapse, the first collapsing beam was even identified after many super computer simulations.

NYC fire cheifs knew those towers may collapse - in a meeting held on the NW corner of that property. Orders went out long in advance to evacuate the buildings because heated steel beams would collapse. Unfortunately, retransmitters necessary to hear those orders could not contact many first responders.

Same concern existed with a Philadelphia skyscraper fire. A long discussion asked two questions. Was steel approaching melting points? And did heat compromise steel water pipes? In that case, heat damage to steel was significant; that the building had to be disassembled.

That conspiracy theory has been widely debunked by so many industry professionals. But it lives on among extremists who know but forget to first learn.

In this London fire, compromised structural beams were reinforced before body searches could commence in some locations.
