The L1649A Starliner was the outgrowth of the L1469/L1569 turboprop designs studied by Lockheed but never produced. Development of the L1649A began in May 1955 and was Lockheed’s response to the long range Douglas DC-7C that went into service in June 1956. The Starliner incorporated a totally new wing design, 3,400 hp –EA2 turbo compound engines and a fuel capacity of 9,000 gallons giving it a range of over 5,000 miles. The first flight of the prototype was October 10, 1956 with TWA introducing the L1649A on its North Atlantic service on June 1, 1957. Sadly, this superb aircraft was developed too late and was quickly overshadowed by the early jets with only forty-four being produced. TWA was the largest operator with twenty-nine aircraft with Lufthansa and Air France also taking delivery of new aircraft. Most were out of front-line passenger service in the beginning of the 60s with a number being converted to freighters and many going to second-tier operators and travel clubs.
