@eaa.oshkosh: On September 14, 1939, the VS-300, the world’s first practical #helicopter, made its brief maiden flight in Stratford, Connecticut. Designed by Igor Sikorsky, it was the first to feature a single main rotor and tail rotor. Sikorsky himself made the test #flight, which lasted only a few seconds. #aviation #aviationlovers #History #firstflight
