His assignment was to work at the supersonic wind tunnels of the rocket laboratories of the German Army. Here Wernher von Braun led a team that developed the V-2, the world's first large rocket-powered guided missile, and laid much of the groundwork for postwar rocket development. In this book, Wegener recounts his experiences during Hitler's time, World War II, and his years at Peenemunde. He tells how he was working one night in August 1943 when the allies bombed the laboratories, but left the wind tunnels undamaged. The tunnels were moved to Bavaria, and Wegener was ordered to follow in 1944. After the war, the tunnels were moved again - this time to the United States, accompanied by the author and other German scientists. Shortly before the end of the war, Wegener visited Germany's underground V-2 production plant to retrieve archival material on aerodynamics that had been stored in caves for safekeeping. He described the appalling history of the concentration camps where SS guards watched over inmates who toiled underground in inhuman conditions and often did not survive. A photo essay enhances this memoir.
