February 18, 1921. Œhmichen helicopter no 1, ships, Egyptian self rule, and Argentine arms.
The early history of the helicopter is complicated, and therefore capable of dispute. Most early flights weren't that, but hops.
This is the first "lift" of an Œhmichen helicopter. The gas bags were for stabilization. Obviously, this would have been a completely useless design but it was pioneering, and the inventor went on to some significant developments in helicopter features. Etienne Œhmichen was a biologist by training and employment.
