Lockheed P-80 Shooting Star at the National Air Races in Cleveland, Ohio

A Lockheed P-80 Shooting Star jet aircraft on the tarmac at the National Advisory Committee for Aeronautics (NACA) NACA Lewis Flight Propulsion Laboratory in Cleveland, Ohio. The Air Force aircraft was participating in the 1946 National Air Races over Labor Day weekend. The air races were held at the Cleveland Municipal Airport seven times between 1929 and 1939. The events included long distance, sprint, and circuit competitions, as well as aeronautical displays, demonstrations, and celebrities. The air races were suspended indefinitely in 1940 for a variety of reasons, including the start of World War II in Europe. The nature of the National Air Races changed dramatically when the event resumed in 1946. The introduction of jet aircraft, primarily the Lockheed P-80 seen here, required an entire separate division for each event. Since military pilots were the only ones with any jet aircraft experience, only they could participate in those divisions. In addition, the performance and quantity of commercially manufactured piston aircraft had increased dramatically during the war. By 1946, the custom-built racing aircraft that made the pre-war races so interesting were no longer present. The P-80 was the first US-designed and US-manufactured jet aircraft. Early models were tested during the war in NACA Lewis’ Altitude Wind Tunnel. A modified P-80 set the world’s speed record at the 1947 air races by achieving 620 miles per hour.
