Zeppelin Piano

The LZ129 Hindenburg featured the first piano ever to be carried on a passenger aircraft.
To meet the strict weight limits of a lighter-than-air dirigible, the Zeppelin company commissioned the renowned piano making firm of Julius Blüthner to create a lightweight aluminum alloy piano, and the Julius Blüthner Pianofortefabrik created a small grand piano that weighed only 162 kg (356 lbs). The frame, rim, fallboard, and top lid were made of duralumin, and the legs, back bracing, and lyre were made of hollow duralumin tubing.
