The registration letters painted on an aircraft's tail are like its number plate: they can reveal the story of an individual aircraft and its different roles during its working life. Inspired by this novel way of looking at aviation history, Guy Halford-MacLeod follows the chequered and multi-faceted careers of forty different airliners to present a compelling insight into the wider story of British aviation: larger-than-life characters, politics, the aircraft manufacturers, the state-owned corporations, the independent airlines, some unwilling buyers, a lot of coercion, big financial losses, cheap holiday charters and, inevitably, going bust - the full story of Britain's airlines and the aircraft they used. This heavily illustrated book delves into the tales of a fascinating selection of aircraft, including many of Britain's finest airliners now preserved at museums around the country, to present the development of Britain's airline industry.
