14/09/1939 Vought-Sikorsky 300 helicopter flies for the first time

The machine was tethered to the ground. It completed its first free flight eight months later. It was the first successful helicopter to use a single vertical-plane tail rotor configuration for antitorque. It beat the endurance record of another early helicopter, Focke-Wulf Fw 61, by sating aloft for 1 hour 32 minutes and 26.1 seconds.
