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 V-1000 Victor. Armed with nuclear weapons and powered by jet engines, these aircraft would be enter service during the 1950s as the V-bombers. The first of the V-bombers to enter service was the Valiant; observing the favourable performance attributes of the Valiant, both the Ministry of Supply (MoS) and Vickers became interested in a prospective transport derivative as a potential long-range successor to the smaller Comet. The RAF had also noticed a demand for a suitable transport aircraft capable of accompanying the V-bombers on deployments to any part of the world, carrying a mix of personnel and cargo needed for such
