Showing Golden Age of the Great Passenger Airships : Graf Zeppelin and Hindenburg by Harold G. Dick

Drawing on the extensive photographs, notes, diaries, reports, recorded data, and manuals he collected during his five years at the Zeppelin Company in Germany, from 1934 through 1938, Harold G. Dick tells the story of the two great passenger Zeppelins. Against the background of German secretiveness, especially during the Nazi period, Dick's accumulation of material and pictures is extraordinary. His original photographs and detailed observations on the handling and flying of the two big rigids constitute the essential data on this phase of aviation history.
