Vickers V-1000 the world's first jet-powered commercial transport aircraft, the Vickers Viscount, the world's first turboprop-powered commercial airliner, and the Bristol Britannia, a turboprop-powered aircraft capable of conducting routine transatlantic flights; all of these designs had their origins in the specifications laid out by the wartime Brabazon Committee. With these aircraft, Britain appeared to be on track to capturing a large slice of the global demand for civil aircraft for the foreseeable future. Meanwhile, the Royal Air Force (RAF) had been pursuing development of a new generation of strategic bombers, these being the Vickers Valiant, the Avro Vulcan, and the Handley Page
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
