Zmc-2The Aircraft Development Corporation ZMC-2 was the first and only rigid metal skinned airship ever built. It was first flown in 1929, and flew safely for over ten years. As a sub-scale test vehicle, it was considered to be very successful, but the company that built it did not weather the Great Depression well, and by the time a successor might have been built, there was little interest in pursuing it. The US-Navy classified it as a blimp. The ZMC-2 was nicknamed the "Tin Bubble" and was also sometimes called a "tinship". It was not made of tin, but of duraluminum, an aluminum alloy. It was strange-looking for a blimp or a dirigble, being teardrop-shaped, and had eight small stabilizer fins, four of which had rudders. It was scrapped in 1941 for its metal content, particullary aluminum. Other blimps did go on to serve in the World War 2 however, specializing in protecting convoys. See also External links
