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
Airliner US, and later designs like the BAC 1-11, Vickers VC10, and Hawker Siddeley Trident although successful would be unable to win a substantial part of it back again. Another committee was formed to consider supersonic designs, STAC, and worked with Bristol to create the Bristol 223 design for a 100-passenger transatlantic airliner. However, this was going to be so expensive to produce that the effort was later merged with similar efforts in France to create the first supersonic airliner—the Concorde. The United States, conversely, gained a huge advantage in design and production in the airline industry in the years leading
