The Invention of the first successful helicopter by Igor Sikorsky

On September 14, 1939, the VS-300, 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 this 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.
