Igor I. Sikorsky's VS-300 was America's first practical helicopter and the first successful helicopter in the world to perfect the now familiar single main rotor and tail rotor design. The VS-300 was first flown (tethered) on September 14, 1939 and the first untethered flight was on May 13, 1940. Testing continued and on May 6, 1941 Sikorsky piloted the VS-300 to a new world helicopter endurance record of 1 hour, 32 minutes and 26 seconds.
On October 7, 1943 the VS-300 was presented to the Henry Ford Museum in Dearborn, Michigan.
