On June 27, 1931, Sikorsky submitted a patent application (no. 1,994,488) for a direct lift aircraft. The patent was granted on March 19, 1935. On September 14, 1939, the VS-300, the world's first practical helicopter, took flight at Stratford, Connecticut. Designed by Igor Sikorsky and built by the Vought-Sikorsky Aircraft Division of the United Aircraft Corporation, the helicopter was the first to incorporate a single main rotor and tail rotor design. Piloted by Sikorsky, the September 14 tethered flight lasted just a few seconds. The first free flight took place on May 13, 1940.
