Background Information:
The ZMC-2 was the only successfully operated metal-skinned airship ever built. Constructed at Naval Air Station Grosse Ile by The Aircraft Development Corporation of Detroit, the ZMC-2 was operated by the U.S. Navy at Lakehurst, New Jersey from 1929 until its scrapping in 1941.

While at Lakehurst it completed 752 flights, and logged 2265 hours of flight time. The ZMC-2 was the brainchild of Ralph Hazlett Upson, a balloonist and engineer. Upson teamed up with Carl B. Fritsche of Detroit and together they formed the Detroit Aircraft Corporation, with backing from Henry Ford and Edsel Ford, as well as Charles Kettering of General Motors, Alex Dow, president of Detroit Edison, and William B. Stout, a local industrialist. Chief of hull design was the young Czech-American designer Vladimir Pavlecka.

The ZMC-2 was nicknamed the 'Tin Bubble' and was also sometimes called a 'tinship'. The skin was not tin but Alclad. The airship was roughly teardrop shaped and had eight small stabilizer fins, four of which had rudders. It was held together with over 3.5 million rivets, which were applied by an innovative sewing machine-like device which produced airtight seams.

The ZMC-2 was constructed out of Alclad, corrosion resistant aluminum sheet formed from high-purity aluminum surface layers metallurgically bonded to high strength aluminum alloy core material. The result was about as strong as carbon. The downside was that Alclad was thicker than sheet aluminum, making the ship several hundred pounds heavier than originally envisioned. [wiki]
