The Second Turbo Three was called the Super Turbo Three because it was converted from a surplus Super DC-3. Unlike the first conversion, the Dart engines were mounted in the rear part of the engine nacelle. Due to the small diameter of the Viscount propellers, airflow was restricted by the bulky nacelles and landing gear fairings. This caused the takeoff distance to be 6000 feet, making it unappealing as a commuter aircraft. The aircraft ended up parked at Groton-New London Airport in Groton, Connecticut where on February 19, 1984 its cockpit was hit by a wing from a Trans American Lockheed L-100 Hercules.
