The typical temerature in the top of a hot-air balloon is 100 deg C. The fabric itself is capable of withstanding over 200 deg C.

Malcolm, I wasn't concerned about the balloon itself, but environment when the balloon (un)intentionally lands.

They said there was not a fire problem on landing because by then, all the fuel had burnt and the fire was out. I guess you could also launch it in an offshore breeze ...

Titanic did not need life boats because it was unsinkable.) If the kids, down under, are playing with fire like your colleagues, does that explain one potential reason for the big fire there was recently?
