meetings including the U.S. national Air Races at Cleveland in September 1937. Here it was reported as handling well both in the air and on the ground. In August 1938, Hawks and his passenger died on colliding with power cables shortly after takeoff. The surviving Aircar was donated to Consolidated Aircraft, Gwinn's old employers, where development continued. Convair 111 After receipt of the Gwinn Aircar, Convair began development of the Model 111 Aircar in 1945, which closely resembled the Gwinn Aircar but had cantilever monoplane wings in place of the biplane layout of the Aircar and a pusher propeller driven by a mid-fuselage mounted Continental A-65. Given the nickname "Pregnant Guppy", ground and wind-tunnel testing revealed low rudder control authority and poor directional stability, as well as problems with engine cooling. Convair persevered with the Aircar until it was deemed uneconomic to continue supplying engines and driveshafts to replace those damaged in testing. Once testing was halted the Aircar slipped into obscurity and was unceremoniously scrapped. Specifications (Niagara II engine) References Notes Bibliography Grey, C.G.
