Convair XFY-1 Pogo VTOL Fighter

The Convair XFY Pogo tailsitter was an experiment in vertical takeoff and landing. The Pogo had delta wings and three-bladed contra-rotating propellers powered by a 5,500 hp Allison YT40-A-16 turboprop engine. It was intended to be a high-performance fighter aircraft capable of operating from small warships. Landing the XFY-1 was difficult as the pilot had to look over his shoulder while carefully working the throttle to land.
