The tragedy was caught on film, radio and pictures. The bad publicity destroyed the future of this type of aircraft. The exact cause of the fire is not known, but there are several theories. One of which was that the skin of the ''Hindenburg'' was waterproofed with [[cellulose]] [[acetate]], which is very flammable, and was coated with the [[aluminium]] powder that is used as a rocket fuel today. Hydrogen burns with a blue flame, however the ''Hindenburg'' burned with a bright red flame. The hydrogen would have escaped upwards when the bladders opened and did not contribute to the disaster. | The tragedy was caught on film, radio and pictures.
