Description
After the Lockheed L-1011 TriStar prototype was first flown in 1970, it was rebuilt around 1975 as the Advanced TriStar, which featured extended wings with active ailerons, reducing drag and enabling the jetliner to fly even when fully loaded. This was incorporated onto the mass production model, of which only 250 were sold instead of the original 500. The Lockheed bribery scandal in Japan led to All Nippon Airways (ANA) cancelling its purchase, and U.S. president Jimmy Carter's promise to focus on human rights in the Cold War, as well as concerns about selling advanced technology to an enemy nation, forced the cancellation of an order from the Soviet airliner Aeroflot. With the loss of these lucrative contracts, Lockheed failed to break even on the TriStar and withdrew from the civil aviation market altogether to focus on military aircraft, marking an unfortunate end to a history that included the Electra, Lodestar, and Constellation airliners. This model of the Advanced TriStar is on display at the Smithsonian National Air and Space Museum's Steven F. Udvar-Hazy Center (Chantilly, Virginia) as a gift from NASA. While NASA itself did not fly the L-1011, this airliner has been involved in the spaceflight industry, as the Orbital Sciences Corporation used modified L-1011 Stargazer to launch the Pegasus rocket.
