In an average winter month, there were only two or three days when visual bombing was possible. In the winter of 1943–44, Pathfinder bombers led forty-eight raids, among them the only missions the Eighth conducted over Germany in November and December. Begun as an experiment, radar bombing soon became routine procedure. Throughout the war, only about half of the Eighth’s heavies bombed visually. In the winter of 1943–44, it was 10 percent.
