My dad used to watch me when I first flown. He once asked me what the white stream was coming from my plane, and I explained that it was leaking fuel. I flown through a fire on the base with this fuel leak. He told me that I should've blown up there. Should've seen the look of surprise on his face when I explained that it wasn't modeled in the game. He didn't say anything further on it, but wasn't fond of it.
I think having fires do damage or 'light your fuel leaks' would be cool. Causing your fuel tank to explode (maybe a new plane explosion 'emote' with this?)
