On 29 February 1940, Hermann Göring issued the order to scrap both "Graf Zeppelins" and the unfinished framework of LZ 131, since the metal was needed for other aircraft. By 27 April, work crews had finished disassembling the airships and recycled all the materials. On 6 May, the enormous airship hangars in Frankfurt were levelled by explosives, three years to the day after the destruction of the "Hindenburg".
