John Killen's exhaustive work is a study of German air power between 1915 and 1945, from the early days of flying when Immelmann, Boelke, Richtofen and other First World War aces fought and died to give Germany air supremacy, to the nightmare existence of the Luftwaffe as the Third Reich plunged headlong to destruction.Here are the aircraft: the frail biplanes and triplanes of the Kaiser's war; the great Lufthansa aircraft and airships of the turbulent Thirties; the monoplanes designed to help Hitler in his conquest of Europe.
