In editor Phil Haun brings together nine ACTS lecture transcripts, which have been preserved in Air Force archives, exactly as delivered to the airmen destined to lead the US Army Air Forces in World War II. Presented is a distinctive American strategy of high-altitude daylight precision bombing as told through lectures given at the ACTS during the interwar period and how these airmen put the theory to the test. The book examines the Air Corps theory of HADPB as compared to the reality of combat in World War II by relying on recent, revisionist histories that have given scholars a deeper understanding of the impact of strategic bombing on Germany.
