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 F.B.5 trainers. The Vickers company persisted with an active experimental program during the First World War period, including a line of single-seat pusher fighters that culminated in the Vickers F.B.26 Vampire of 1917-18, but the F.B.5 remained their only significant production aircraft until the Vickers Vimy bomber, which entered service too late to affect the war. Despite its moderate effectiveness, the Vickers F.B.5 did have a lasting legacy as German pilots continued to refer to British pusher aircraft as "Vickers-types". Many victories over D.H.2 or F.E.2b pushers were reported as destruction of a "Vickers". A flying replica of the F.B.5 Gunbus
