The largest manmade object ever to fly, the 800-foot airship Hindenburg erupts in a fireball at Lakehurst, N.J., on its arrival from Europe on May 6, 1937. Static electricity ignited the airship's flammable fabric skin, and 37 seconds later the airship crashed to the ground, killing 35 of its 97 passengers and crew. This spectacle ended the era of the passenger airship. Photo by Sam Shere/INS/UPI
