The Chance Vought F4U Corsair was a fighter aircraft that saw service in World War II and the Korean War. Goodyear-built Corsairs were designated FG and Brewster-built aircraft F3A. When flown in 1940, the XF4U-1 became the first U.S. single-engine production aircraft capable of 400 mph in level flight. It was a remarkable achievement for Vought, as carrier aircraft are, compared to land-based counterparts, overbuilt to withstand the extreme stress of deck landings. The Corsair is also popularly known as 'The Sweetheart of the Marianas' and sometimes also as 'The Sweetheart of Okinawa' for its roles in these campaigns respectively - the names were given by ground troops rather than by Naval and Marine personnel. The Corsair has been named the official aircraft of Connecticut, due to its connection with Sikorsky Aircraft, in legislation sponsored by state senator George "Doc" Gunther; Gunther has also organized a Corsair Celebration and Symposium at Sikorsky Memorial Airport in Stratford, Connecticut, on Memorial Day, May 29, 2006.
