According to Wikipedia: "The Hindenburg was a large German commercial passenger-carrying airship (commonly referred to as a zeppelin). It was the largest flying machine of any kind (by dimension) ever built. The airship flew from March 1936 until it crashed and was destroyed by fire fourteen months later on May 6, 1937, at the end of it's first North American transatlantic journey. Thirty-six people died in the accident, which occurred while landing at Lakehurst Naval Air Station in New Jersey. The Hindenburg was named after the late Paul von Hindenburg (1847–1934), President of Germany (1925–1934)."
