Early post-war operations
BOAC was also permitted to spend dollars on six new Boeing 377 Stratocruisers for its key transatlantic routes from October 1949, offering a double-deck non-stop eastbound service from New York City to London Airport (later Heathrow). However, because of the prevailing westerly winds, the westbound flights needed re-fuelling at Shannon and Gander before reaching New York. Another four Stratocruisers were taken over from a frustrated SAS order and seven were bought secondhand in the mid-1950s. The Handley Page Hermes and Canadair DC-4M Argonaut joined the BOAC fleet between 1949 and 1950, replacing the last of the non-pressurised types on passenger services. When service entry of the Bristol Britannia was delayed in late 1956, BOAC was permitted to purchase ten new Douglas DC-7Cs. These long-range aircraft enabled BOAC to operate non-stop westbound flights from London and Manchester to New York and other US East Coast destinations, in competition with DC-7Cs of Pan Am and Lockheed Super Constellations of Trans World Airlines (TWA). This was the first purchase of aircraft direct from the Douglas Aircraft Company in BOAC's history.
