The two "Hindenburg"-class airships were hydrogen-filled, passenger-carrying rigid airships built in Germany in the 1930s and named in honor of Paul von Hindenburg. They were the last such aircraft to be constructed, and in terms of their length, height, and volume, the largest aircraft ever built. During the 1930s, airships like the "Hindenburg" class were widely considered the future of air travel, and the lead ship of the class, LZ 129 "Hindenburg", established a regular transatlantic service. The destruction of this ship in a highly publicized accident was to prove the death knell for these expectations. The second ship, LZ 130 "Graf Zeppelin", was never operated on a regular passenger service, and was scrapped in 1940 by order of Hermann Göring.
