Through subsequent chapters, Davis reveals many important points that greatly affected the war effort: * Reluctance of Allies to admit to city bombing until the end of the war despite dedicating numerous sorties for this purpose. * Arguments between advocates of the Royal Air Force's (RAF) night bombing and those who championed the Army Air Forces (AAF) daylight bombing, leading to creation of the Combined Bomber Offensive. * Gen Carl Spaatz's and other commanders' combat-tour policies and their effect on morale and survival of aircrews. * Radar development and testing on aircraft by the RAF and modifications by the AAF. * Mine-laying operations and their value. * Development of long-range fighter escorts as the Eighth and Fifteenth Air Forces sustained high casualty rates while bombing deep into Germany.
