Stratford, Connecticut – September 15, 1974
Sikorsky Airport
On the evening of September 15, 1974, an experimental helicopter containing four men and one woman was taxing onto the airfield at Sikorsky Airport when it suddenly exploded. The helicopter, a YCH-53E (Sea Stallion) prototype, was about to begin a demonstration test flight in the hopes of gaining a contract with the U.S. Navy or Marines.
All five persons aboard suffered severe injuries and burns.
By the time the fire was extinguished only the nose and tail section remained.
