DESCRIPTION: A spy for our soldiers in 1940, an artillery adjustment plane or a rescuer for our wounded in Indochina or in AFN, then a tug for our vlivoles of the Sixties, the Storch is now a star at airshows. We will discover together its history, its many adaptations and its exploits. This work has been carried out drawing on a large amount of both public and private archives. These have been exploited by avoiding repeating statements based on hearsay. Indeed, a large number of sometimes fanciful statements have been made about this device and it has been attempted to take stock each time an original technical documentation existed. Completeness is not claimed, but has been attempted to come close. The reader will undoubtedly understand the complexity of the task and will certainly apologize for any errors or omissions that may arise. This is particularly true for the history of each French device that completes this work. The archives of the post-war period are very incomplete, human memory was then more in demand and traceability not yet fashionable ... The author simply hopes that this book will bring back fond memories to pilots who, like him, were lucky enough to fly it, to glider pilots who, like him, were towed by the "Storch" and will help all those who restore. or maintain this wonderful machine ... About 320 pages, more than 380 photos, diagrams and plans as well as about twenty color profiles.
