Burning requires OXYGEN. in a NORMAL FIRE the only source is the air. How can it reach those temperatures without a good air supply.
What makes you think the fire didn’t have a good air-supply? There was air all around NYC and the Towers that day? Gosh! I think people were in those buildings breathing air every day!
I don’t recall people going to work there with SCUBA gear.
Fire just naturally sucks air into it! Just like the fire-bombings of Dresden and Hamburg. Large, high temperature fires in the cities core, winds of up to 200 m.p.h. sucking into the city!
Yeah! Well documented. I’m pretty sure there was air up there that day…a pretty good unlimited supply!
