Rep., 2011. 406 pp., photo-plates. D.j., 24 x 15cm. Upper and lower edges of inside flaps (only) of d.j., very narrowly trimmed, not affecting any text, with a little faint scuffing from tape to pasted e.p.'s & a small owner's label to f.f.e.p., o/w Nr.FINE. This is the thrilling, little known story of the partner organisation to the famous code-breaking centre at Bletchley Park. It tells of the daring reconnaissance pilots who took aerial photographs over Occupied Europe during the most dangerous days of the Second World War, and of the photo interpreters who invented a completely new science to analyse those pictures. They were inventive and ingenious ; they pioneered the development of 3D photography and their work provided vital intelligence throughout the war. The interpreters were based at Medmenham in the Thames Valley and their work was arguably even more important to the outcome of the war than that of the Bletchley Park code-breakers. The intelligence gathered there covered almost every aspect of the war : from finding the BISMARCK to tracking down Hitler's V-weapons in 1944 ; from clearing the Mediterranean and the success of D-Day to the disaster at Arnhem. With a whole host of larger-than-life characters at its heart - from the legendary pilot Adrian 'Warby' Warburton, who went missing while on a mission, to photo interpreters Glyn Daniel, later a famous television personality, and Winston Churchill's daughter, Sarah, this book is compelling reading and the first full account of the story of aerial photography and the Intelligence gleaned from it in nearly fifty years.
