Lockheed L-1649 Starliner
Pratt & Whitney dropped the PT2 project in March 1955 due to expected unreliability, high specific fuel consumption and high operating costs,[citation needed] though the T34 military version of the engine powered the Douglas C-133 freighter, which was also plagued with unreliability.The new design used the L-1049G fuselage, the new 150 ft (46 m) wing and four Wright R-3350 988 TC18-EA-2 turbocompound radial engines, allowing the Starliner to fly nonstop from California to Europe.Lockheed said the new L-1649A would deliver 58 passengers over a range of 6,500 mi (10,500 km) at 350 mph (560 km/h), or from Paris to New York City three hours faster than the DC-7C.In September 1957, a Starliner made the first nonstop flight from Los Angeles to London; this was captained by TWA’s chief pilot, Bob Buck, who wrote an extensive magazine article describing the experience.[7] Boeing 707s replaced the last TWA transatlantic passenger L-1649 in October 1961; 707s and Convair 880s displaced them from domestic scheduled flights in December 1962.Starting in April 1958 Air France L-1649s flew from Paris to Anchorage to Tokyo, but they were not allowed to fly to the west coast of the United States.The DC-7C ended up selling more airframes than the Starliner, which had greater range than its rival but was expensive ($3,000,000 USD) and entered service a year later.
