Jet Fuel has changed a lot since the F9.

I bring up the F9 because i know that plane better than any other.

Gavin, im talking about civilian jet fuel. I know the military has different sorts of jet fuels most common of which are kerosene based fuels.

and im talking about all jet fuel, the military is simply an extreme example, most civilian jets use mixtures too, either for cost reasons, or to reduce stress on the aircraft's engine.

Jet fuel burns at 800° to 1500°F.

Most jet fuel*

, not hot enough to melt steel (2750°F)

Does not need too, the plane smashing into the building creats a **** ton of heat and realeses a **** ton of energy too, the burning just weakens the steal, also, we dont even know what grade steel these towers where built with, as a son of a contractor, i can say almost none of these buildings meet code.
