This first part of a two-volume publication is not simply a new version of Air-Britain’s famous 1984 edition – it is vastly expanded and revised. The two volumes amount to over 700 pages with some 140 colour photos added to an extensive new black and white section. Drawing on the expertise of many specialists from around the world, this book contains the results of painstaking research on civil aircraft and is supported by a wealth of previously unpublished information on military use in the USA, UK, Canada, Australia, South-East Asia and elsewhere. The book provides full details of the known histories of almost 11,000 aircraft that were built in the United States, with added sections on the Ll-2 and Japanese production, as well as the various Turbo conversions. Plus, there is an invaluable regn-c/n cross-reference and extensive details of the operators that flew, and still fly, this amazing aircraft.
