History
Lockheed launched the L-1011-500 in 1976 and it first flew in October 1978. British Airways, its first customer, took delivery on April 30, 1979 and started flying it in May, and Delta used it on its Atlanta to London route. Pan American, Air Canada and the Royal Air Force were among its operators, and the RAF later converted some into tankers. Production of all TriStars ended in 1983. Delta, the largest TriStar operator, retired the type from scheduled flying on July 31, 2001.
