The Lockheed L-1649A Starliner was the final derivative of the highly successful Constellation and Super Constellation series of airliners. Its very long range gave airlines the opportunity to schedule non-stop services between Europe and the US west coast and to operate ‘over the pole’ to Japan. Unfortunately, it was beaten into service by the similarly-capable Douglas DC-7C, and with the early transatlantic jets on the horizon, its sales were poor.
