Jack McKillop: "This aircraft, owned by Lockheed, was the original prototype which made its first flight on November 16, 1970 powered by Rolls-Royce RB-211 jet engines. It was subsequently equipped with more powerful engines and served as a test aircraft for improved models of the TriStar. As the Advanced TriStar, it was used to test automatic landing equipment, automatic brakes, flight management systems, etc. Beginning in 1977, it was used to test wings of increased span to enable higher gross weights and improved fuel economy under a NASA-funded program. The aircraft was withdrawn from use and scrapped for spares at Ardmore, Oklahoma, USA, in August 1986. The forward fuselage was shipped to Disney World in Orlando, Florida, USA. The registration was cancelled on April 27, 1992."
