This is a detailed review of the establishment and activities of government flight-test centers in Germany from the resumption of flight testing in the 1920s until the end of the Second World War. The authors begin with the secret testing in cooperation with the Red Army in the 1920-30s and cover the major locations where testing was conducted including Johannisthal, Lipetsk, Rechlin, Travemünde, Tarnewitz and Peenemünde-West. Other less well-known locations including early experimentation at Döberitz and Danzig are also covered.
The book draws on an extensive collection of photographs and documents, many taken from previously unpublished sources. There are also comprehensive listings of the aircraft used, with such details as Werknummern, markings and engines. There are similarly detailed lists of personnel and the various research and test units.
