This is my first venture into this forum. Nobody seemed to be doing anything in GD or GP, and the title caught my eye. I don't have time to read most of the foregoing -- a half dozen or so posts -- but thought that you might be interested in this. Although he certainly doesn't purport that dragons really existed, Larry Niven (one of the gods of hard SF) detailed how they could. I can't remember which book it was in, or exact details. Basically, it was thus:
large reptillian lifeform that reprocesses its gastrointestinal methane and stores pure hydrogen in a cavity similar to the swim bladder in a fish; bouyancy allows it to float like a balloon, so small wings are enough for propulsion and manoeuvring; fire breathing is achieved by releasing some of the hydrogen in a jet and igniting it by gnashing its teeth, which incorporate iron pyrite instead of calcium in their enamel
I think that there's even more to it than that, but you see what I mean.
I'm outta here now; have fun.
