This classic image of the USS Los Angeles shows what would happen when a gust of wind caught the backend of a moored airship. It could literally turn a 1,055m big blimp vertical. Amazingly, no one was hurt.
It looks like a laughably ginormous bomb was about to be dropped on top of a radio tower, doesn't it? But more seriously, it happened because a cold air front lifted the airship's tail before the airship could swing around the mast. This 1927 incident showed the risks involved with high mooring masts, risks that the Navy eventually would address and make safer. [Naval History via Flickr via BoingBoing]
