No but they did have armor over 4-5 CM thick which is pretty fire retardent.

Yes if exposed to enough heat, a simple blast from a flamethrower would not set it alight and that hits temperatures of past 1000°C.

Yes to set it off, but onlike humans I do not think dragons would fly to their nearest gas station to refuel on a flamable substance for the spark to actuall set off.

Yes which aids the fact that they would be less lightly to evolve it as all that hydrogen would be energy that the dragon could absorb and use itself to move and fly and fight. Remember that such bacteria would be atmost 50% energy efficent, which would mean that all that combustion energy would usually be absorbed by the dragon for and movement growth at a near 80%+ effcency (yes reptiles are a hell of a lot more efficent than us humans which only absorb about a quarter of the energy out of the food in the firstplace). Thus it would only make their survival less suscesful and so it would not form in the first place.

Very bad evolutionary trate, since the more they would breathe, the harder it would be to run away. Also you are aware HOW MUCH hydrogen is required to lift any serious volume and how easilly it escapes? No organic system can contain pure hydrogen without it gradually escapping, this is because the molecules are so small that they squeeze inbetween cells and through cells. The only real way to keep hydrogen is in metal (due to it being a higher density) and I dought dragons would have a huge sack filled with it made of solid metal, as the metal would weigh more than the hydrogen would displace.

Also hydrogen is a CRAP flamable fuel. It is one of the worst you can get because it burns in an almost explosive like manner (would hardly go far if breased out as a flame thrower) to form water which then absorbs most of the energy given out to form water vapour due to water's high latent heat capacity. This means that the average flame would reach no more than 250°C out side the mouth (the mouth being much hotter because most of the burning would occure there due to hydrogens explosive nature) which would inflict nothing to the scales of other dragons and would only badly burn some. Thus reducing the likly hood even more.

The entire idea was probably generated by some science fiction writer and they purly asked "experts" to pretend it was possiable. I definatly would not trust it if it was from the discovery channel as that is mostly "Ge WIZ" and not very scientific.

Remember that most things on TV are fake, and theroies like this can be written by 1-3 scientists that purly want fame without it being physcally possiable. It is like the ploy with putting solar technology in london which never pays off for its self, looks good from the outside actually is impossiable when looked into. Something like dargons is extreemly likly to be fake as it is so easy to make people believe anything you say about it, as they never existed.
