"File No: 47150 November 25, 1944. Eyes and "Mechanical Brain" on the target. Bombardier of a Navy plane uses famed and still secret Navy Norden bombsight to determine just when to release his bombs. Designed by Carl L. Norden and Captain Frederick I. Entwistle, USN, Assistant Chief of Research and Development of the Bureau of Ordnance, the bombsight is used by Army as well as Navy and Marine bombers. The device, when fed certain information by the bombardier, computes how far ahead of the target the bombs must be dropped to "arc in" to the objective." 25 November 1944
