Overview
Lockheed's only jet airliner, the TriStar was technically ahead of its time, with Rolls-Royce RB211 engines and an autopilot that could land the aircraft in fog. Engine development problems drove Rolls-Royce into bankruptcy in 1971 and delayed the programme, and only 250 were sold before Lockheed left the airliner business.
Air Lanka, the forerunner of SriLankan Airlines, flew TriStars on its international network in the 1980s and 1990s. Specifications are for the L-1011-1; the long-range L-1011-500 could fly about twice as far.
