it made a seven-day research trip to the Arctic. This had already been a dream of Count von Zeppelin twenty years earlier, which could not be realized at the time due to the outbreak of war. Eckener intended to follow the successful airship with another larger Zeppelin, designated LZ 128. This was to be powered by eight engines, in length, with a capacity of . However the loss of the British passenger airship R101 on 5 October 1930 led the Zeppelin company to reconsider the safety of hydrogen-filled vessels, and the design was abandoned in favour of a new project, LZ 129. This was intended to be filled with inert helium. Hindenburg, the end of an era The coming to power of the Nazi Party in 1933 had important consequences for Zeppelin Luftschiffbau. Zeppelins became a propaganda tool for the new regime: they would now display the Nazi swastika on their fins and occasionally tour Germany to play march music and propaganda speeches to the people. In 1934 Joseph Goebbels, the Minister of Propaganda, contributed two million reichsmarks towards the construction of LZ 129 and in 1935 Hermann Göring established a new airline directed by Ernst Lehmann, the Deutsche Zeppelin Reederei, as a subsidiary of Lufthansa to take over Zeppelin operations. Hugo Eckener was an outspoken anti-Nazi: complaints about the use of Zeppelins for propaganda purposes in 1936 led Goebbels to declare "Dr. Eckener has placed himself outside the pale of society. Henceforth his name is not to be mentioned in the newspapers and his photograph is not to be published". On 4 March 1936 LZ 129 Hindenburg (named after former President of Germany, Paul von Hindenburg) made its first flight. The Hindenburg was the largest airship ever built. It had been designed to use non-flammable helium, but the only supplies of the gas were controlled by the United States, which refused to allow its export. So, in what proved to be a fatal decision, the Hindenburg was filled with flammable hydrogen. Apart from the propaganda missions, LZ 129 was used on the transatlantic service alongside Graf Zeppelin. On 6 May 1937, while landing in Lakehurst after a transatlantic flight, the tail of the ship caught fire, and within seconds, the Hindenburg burst into flames, killing 35 of the 97 people on board and 1 member of the ground crew. The cause of the fire has not been definitively determined.
