LZ 129 Hindenburg (Luftschiff Zeppelin #129; Registration: D-LZ 129) was a German commercial passenger-carrying rigid airship, the lead ship of its class, the longest class of flying machine and the largest airship by envelope volume. It was designed and built by the Zeppelin Company (Luftschiffbau Zeppelin GmbH) on the shores of Lake Constance in Friedrichshafen, Germany, and was operated by the German Zeppelin Airline Company (Deutsche Zeppelin-Reederei). It was named after Field Marshal Paul von Hindenburg, who was President of Germany from 1925 until his death in 1934.

The airship first flew from March 1936 as a Nazi propaganda vessel until it burst into flames 14 months later on May 6, 1937, while attempting to land at Lakehurst Naval Air Station in Manchester Township, New Jersey, at the end of the first North American transatlantic journey of its second season of service. This was the last of the great airship disasters; it was preceded by the crashes of the British R38, the US airship Roma, the French Dixmude, the USS Shenandoah, the British R101, and the USS Akron.

Design and development

The Zeppelin Company had proposed LZ 128 in 1929, after the world flight of the LZ 127 Graf Zeppelin. This ship was to be approximately 245 m (804 ft) long and carry 140,000 cubic metres (4,900,000 cu ft) of hydrogen. Ten Maybach engines were to power five tandem engine cars (a plan from 1930 showed only four). The disaster of the British airship R 101 prompted the Zeppelin Company to reconsider the use of hydrogen, therefore scrapping the LZ 128 in favour of a new airship designed for helium, the LZ 129. Initial plans projected the LZ 129 to have a length of 248 metres (814 ft), but 11 m (36 ft) was dropped from the tail in order to allow the ship to fit in Lakehurst Hangar No.
