Yeah, I get it, saw those early reports in the '80s. And the reports in the '90s of how prohibitively expensive it would be to remove the asbestos based fireproofing and replace with better insulation throughout the complex. Then Larry Silverstein leases the complex for 99 years in June 2001, fully insuring it, 2 months later it goes down. Insurance pays Larry Silverstein $4.6B **and** cleans up the mess. >Jet-A, being Kerosene with stuff in, will burn at well over 2000°F when given some airflow, and probably did so because of all the ample polyester, pressboard, and paper present in an office The paper, carpets, cubicles, etc in my estimation contributed ~5% of the heat generated compared to a plane full of fuel. The volume of fuel Btu's contributed an order or two of magnitude more heat than the paper and plastics. I don't know if the steel exostructure failed or not. In my mind IF the steel fatigued from heat, it should have slowly tilted off center toward the leeward side before coming down. Wind forces were pressing against the windward side thus trying to compress the leeward side and the heat emanating from the fire mostly exits the leeward side which makes those leeward steel beams more susceptible to heat and stress, they should have failed first if any of the beams were to fail. I think we agree, a lot of things just don't add up in the official narrative.
