BAC One-Eleven suffered disasters in service, strong passenger demand had been demonstrated for jet propulsion. Several manufacturers raced to release passenger jets, including those aimed at the short-haul market, such as the Sud Aviation Caravelle. In July 1956, British European Airways published a paper calling for a "second generation" jet airliner to operate beside their existing turboprop designs. This led to a variety of designs from the British aerospace industry. Hunting Aircraft started design studies on a jet-powered replacement for the successful Vickers Viscount, developing the 30-seat Hunting 107. Around the same time, Vickers started a similar development of a 140-seat derivative
Vickers-Armstrongs company produced the Wellesley, designed by Rex Pierson using the geodetic airframe principle of structural engineer Barnes Wallis. This would later evolve into the famous Wellington bomber, a mainstay of RAF Bomber Command and RAF Coastal Command during World War II. The Cold War-era Valiant V bomber was another Vickers product. Military aircraft with the Vickers brand: Vickers also competed for contracts with designs such as: Vickers was a pioneer in producing airliners, early examples being converted from Vimy bombers. Post-WWII, Vickers went on to manufacture the piston-engined Vickers VC.1 Viking airliner, the Viscount and Vanguard turboprop airliners and (as
