Operation Argument (‘Big Week’): The beginning of the end of the German Luftwaffe
A formation of B-17 Flying Fortress aircraft on the way to bomb industrial targets in Germany, early 1944. Starting in late 1942 through October 1943, B-17s, along with B-24 Liberator strategic bombers conducted unescorted daylight precision bombing raids on German industrial targets. However, these raids temporarily ceased after the disastrous unescorted raids in August and October 1943 produced unsustainable aircraft and aircrew losses. (U.S. Air Force photo)
