I thought helium, the gas is actually "renewable" hydrogen. oh boy.
Helium would be too expensive for this big boy. Can you say reserve

Hydrogen is unlikely to burn at those altitudes. Even down lower, it still needs to exit the balloon and mix with oxygen to burn. The Hindenburg did not burn because of the hydrogen. It was that very flammable envelop made from dope (acetate resin) with aluminum dust.
