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 E.F.B.1 to be started on another aircraft of similar design, the Vickers E.F.B.2, and this line of development would eventually lead to the Vickers F.B.5 Gunbus. Vickers E.F.B.1 The Vickers E.F.B.1 'Destroyer' was an early British military aircraft prototype. Although not itself a success, the design was considered worth developing, and a series of similar aircraft were produced in prototype form, eventually leading to the Vickers F.B.5 "Gunbus", which saw widespread service during World War I. The Experimental Fighting Biplane No. 1 (E.F.B.1) was designed in response to a British Admiralty requirement for an aircraft intended for an offensive role. As
