Jet fuel can burn as high as 1000* F, and the critical temperature for structural steel is 540* F

Its pretty hard to ignite jetfuel, like JP-8 or Jet A-1 it really needs to be pressurized to ignite…

no, structural wont unless its cycled many times.

Point being…a candle flame produces temperatures of 650°F … i’m willing to be this fire was well over 1000°F

A quick read of that article…

Color tells us about the temperature of a candle flame. The outer core of the candle flame is light blue – 1670 K (1400 °C). That is the hottest part of the flame.

i was rather shocked about this temp too… I thought it was roughly 650F too… I’m pretty sure since gasoline is an accelerant (may not be the right word) gasoline burns even hotter than a candle would…
