October, 1934: The vast and intricate framework of zeppelin model LZ 129, under construction at Friedrichshafen, Germany. With a gas capacity of 7,070,000 cubic feet, and christened “Hindenburg,” she became largest airship in the world.
While it was known that hydrogen was highly flammable, it was also far less expensive and far more plentiful than utterly safe, lighter-than-air helium, thus it was Hydrogen filled
Herbert Morrison was a radio announcer on the ground at Lakehurst when the Hindeburg burst into flame. Listening to a recording, or even reading a transcript, of his intensely emotional narration of the disaster is still, seven decades later, heart-rending. (His famous shouting of the phrase, “Oh, the humanity!,” meanwhile, has become something of a punchline.)
