"Black jet fuel smoke indicates a burning temp of approx 500F..."

Ah! well, if thatwere ALL that were burning, but have you ever seen plastics burn? 10 floors of synthetic materials, computer cases, furniture, etc - thus 'black smoke' is not a realistic indicator of the actual temperature of the fire.


"About the same as broiling bacon?"

Ah, I used to be into the "spontaneous human combustion" thing years ago, before it was debunked... but I won't say any more... ;-)
