US Navy C-5 airship. This hydrogen airship was operated by the US Navy between 1918 and May 1919. It was one of ten C-class blimps built by Goodyear and Goodrich. It had a crew of four, with a large ground crew needed to land and launch it. 60 metres long, it had a range of 2320 kilometres, and could fly at heights of 2.5 kilometres powered by its fuel engines. It was armed with a machine gun and bombs. With no crew on board, it was torn loose from its moorings in high winds in St John's, Newfoundland, on 15 May 1919, crashing in the Atlantic later that day.
