The Second-Generation Norden Bombsight Vault at the former McCook Army Air Base near McCook, Nebraska, is an example of the structures used by the military to help ensure the secrecy of this advanced technology device during World War II. The military quickly decided that strategic bombing would play an important role in the war. The Norden Bombsight was crucial in conducting that high-altitude precision strategic bombing by the U.S. Army Air Force and an essential factor in defining air war strategy. The sight was a highly accurate precision instrument developed by Carl L. Norden, a civilian consultant, and Captain Frederick I. Entwhistle, assistant research chief of the U.S. Navy's Bureau of Ordnance. In 1932 the U.S. Army Air Corps ordered its own Norden bombsight.
Charles D. Bright described the sight in his Historical Dictionary of the U.S. Air Force:'Precision bombing required meticulous control; to accomplish this, the Norden incorporated a gyrostabilized automatic pilot. The mechanism was modified in 1941 by the Minneapolis Honeywell Company and designated the Army C-1 autopilot. This modification enabled a bomber to be flown on a straight, level course, giving the bombardier a steady platform on which to operate the bombsight during the bombing run. Also known as the 'Blue Ox' the Norden could quickly calculate and correct directional changes due to wind drift. Flying at a preset altitude, it could rapidly compute the correct bomb release angle for a constant speed of closure to the aiming point. Under optimal conditions on an undisturbed run, the accuracy of the device was excellent. However, any last second changes in the altitude of the bomber, such as those encountered during battle, could markedly influence the accuracy of the sight.'
