L-1011 Delta

"The Lockheed L-1011 TriStar is a three engine jet airliner. The L-1011 TriStar was the last Lockheed airliner to be developed and was launched in March 1968 in response to an American Airlines requirement for a large capacity medium range airliner. The L-1011-1 was the first production model of the L-1011 which entered service with Eastern Airlines and TWA in April 1972. It was designed for short and medium-range flights and was purchased by Air Canada, ANA, Cathay Pacific, Eastern and other operators with regional trunk routes requiring a wide-body aircraft. Pacific Southwest Airlines purchased two L-1011 models with lower deck seating. This variant was also the only wide-body ever to have the option for a full-height built-in airstair incorporated into the design, although it remained an option on other variants. In 1983, production of L-1011-1 ceased when 250 had been built. In 1986, the prototype was sold to be broken up for spares. The L-1011-1 TriStar has a cockpit crew for three and has a seating capacity of 253 in a 3-class. It has a maximum speed of .95 Mach and a range of 4,610 mi. There are approximately 156 TriStars which remained in service in 1998, with 122 standard fuselage models. In 2000, the number went down to about 137, with 109 standard fuselage models. By the end of 2002, it dropped further to 51 active TriStars, with 23 standard fuselage ones. Delta retired its TriStar fleet in 2001, replacing them with the Boeing 767-400ER. The airplane was also used in the television series Lost, featuring a dismantled L-1011 formerly belonging to Eastern Airlines."
