The information on this site has been gathered from many sources. This page contains the books, magazines, etc, I have used for the production of the site. However since our collection of Imperial Airways material has been accumulated over the years, and this includes old photocopies and clippings from publications, it is not always possible to credit the original source, but we have endeavoured to do so whenever possible. British Civil Aviation Archive British Commercial Aircraft 1920-1940 - Arthur Ord-Hume/GMS Enterprises Imperial Airways and the First British Airlines 1919-1940 - Terence Dalton, The Illustrated Encyclopedia of Aircraft - Aerospace,   Handley Page Aircraft since 1907 - Putnam, Images of Aviation series (various) - Tempus, Cigarette Card albums - Brooke Bond, Lyons Teas, and John Player & Sons, Model Kits - Airfix, Stan and Diane Holmes - Wartime photographs for gallery And not forgetting: John Charles and Frank Gray for their continuing help. All images on this site are from a private collection. Where other images have been used, the sources have been credited where possible.
