Not to be anal but just worth knowing:
The Hindenburg was POWERED by 4 1200HP V-16 Mercedes-Benz Diesel motors, FILLED with hydrogen, and WENT DOWN over Lakehurst, NJ. Yes that's in the US
Only 2 people died as a result of burns while 33 died from jumping from the craft. Also it's worth mentioning that the fire started on the highly flammable aluminum powder coated skin NOT because of the Hydrogen.
