Meanwhile, the Royal Air Force (RAF) had been pursuing development of a new generation of strategic bombers, these being the Vickers Valiant, the Avro Vulcan, and the Handley Page
Regional airliner and British Aerospace ended production of their BAe Jetstream 41 after 100 delivered. By 2006 only the ATR 42/72 models and the Dash 8 remained in production.

Although a number of small jets entered service in the 1950s and 60s, notably the Sud Aviation Caravelle, Fokker F28 Fellowship and DC-9, these could not compete in terms of cost of operation with the turboprop designs, and were suitable for
