Thanks guys, and that's another nice P.1154RN too Darth!
In February 1958 BOAC began its first non-stop transatlantic service with the Avro Atlantic airliner, based on the wings of the Vulcan bomber. BOAC had operated some shorter commerical routes during late 1957 on its Empire routes and to European capitals. It was the first Avro 'flying-triangle' to reach Moscow in July 1958.
Not content to see a good thing wasted the RAF managed to get the Trreasury to approve the purchase of ten Atlantic C.Mk.1 transports alongside its five Comet C.Mk.4 transports. These were in use until 1975.
