The Hindenburg was supposed to be a demonstration of the future of travel. The idea was that everyone would be amazed by the breathtaking balloon, and everybody would want to take a ride on it. Instead, it ended up disaster and tragedy.
On May 6th, 1937, the Hindenburg took to the skies. As it came back in to dock, a stray spark ignited the hydrogen inside the balloon, and there was an enormous explosion. 36 people were killed, and many more were injured.
