> claiming jet fuel can't melt steel beams Just note: Jet Fuel probably can't melt steel beams, because steel has a significantly higher melting point than the temperature of jet fuel. Of course, Steel Beams are about as strong as a wet-noodle at Jet-fuel temperatures: https://youtu.be/FzF1KySHmUA?t=1m55s Which of course, would cause the towers to collapse. But seriously, Jet Fuel doesn't "melt" steel beams. It just…
Also there were documented hotspots that were in excess of steel melting temperature. This was due to regular office debris being burnt quickly, thanks to the jet fuel that had catalyzed it when it sprayed out into the center and floors above and below the crash site. I read about this in the excellent 9/11 debunk series by Popular Mechanics.
We tried the (UL approved) office debris theory: https://www.youtube.com/watch?v=VvQDFV1HINw (yt may axe that chan)
