Yep to be fair. Temperature after combustion is around 1500C to 2000C but not for very long.
Correct me if I'm wrong but they have to cool it with extra air in the flame tube. Otherwise the components would melt.
However half the sun's surface temperature is 2700C.
But i guess it sounds more dramatic if I add that. Same as planes falling out of skies (okay he didn't say this but he didn't correct it either)
