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 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 such, it was notable for being the first British aircraft to be specifically designed for a military role. A contract for an experimental prototype was
