Lockheed XFY-1 Pogo VTOL Aircraft 3D model

The Pogo, as the XFY-1 was called, had a short, stubby fuselage, on which were mounted two near-delta wings and two enormous fins, one ventral and one dorsal, giving the arrangement a cruciform appearance. A small wheel was attached to the apices of all four of these surfaces and when parked, the aircraft rested, nose in the air, on these four wheels. Power was supplied by a 5,850hp Allison YT40-A-6 turboprop engine, driving two coaxial propellers and a large spinner. The ventral fin could be jettisoned in flight were it necessary to make an emergency belly landing (on land or sea). By March 1954 the prototype was completed and taken to Moffett Field naval base in California where, inside an enormous hangar, braced by a special rig to prevent any possible chance of the aircraft toppling over, powered tethered tests were carried out, during which the aircraft was allowed to lift itself a few inches off the ground.
