How hot should this "office fire" have gotten? Please include local temps. If you don't understand this (it's been covered here to death) you can't accept claims that these temps are high. Does this make sense? That article does go into how local temps can get very high.
I think a realistic temperature for the office fires is 1100C.
Also, the fires didn't last that long, and they weren't all that insulated either.
How hot do you do think the fires could have gotten in the pre-collapse office fire?
I've seen sources from JOM that state the steel temps in the office fire of WTC would have reached between 750 and 850 C.
