Critics of the Army Air Forces argued that the strategic bombing campaign was unnecessary. All the production devoted to building bombers and the enormous effort to train men to fly and maintain them could have been better spent on fighters, ground troops, and the Navy. It would also have avoided the worst accusation of all: that the United States used a method of making war that killed hundreds of thousands of civilians. The bombs hit residences as well as factories, deliberately on the part of the RAF Bomber Command’s night bombing, but also from the American precision bombing, for the accuracy of free-falling bombs was far below the accuracy of artillery fire. Most bombs fell considerably outside their targets. Asked after the war, “Did you guys ever hit anything?,” one tail gunner replied, “Yeah, we always hit the ground.”
