1. Bombsite Storage Building Marker
Inscription.  Barbed wire encircled this double-compartment storage building and a 24-hour sentry kept armed guard. The top secret Norden bombsight, a mechanical analog computer, was accessed through bank vault doors, removed carefully for training missions, and returned under armed guard. The 50-pound instrument was used to determine the exact moment a bomb should be released. The bombsight contained 2,000 precision parts. Its accuracy depended upon the bombardier’s ability to correctly calculate speed, altitude, temperature, barometric pressure, and the “bomb curve.” Setting the instrument required such precision that one reporter likened it to playing a violin. Wearing silk gloves so that his fingers wouldn’t stick to the metal and breathing pure oxygen in temperatures reaching 40 degrees below zero, the bombardier crouched in the Plexiglas nose of the aircraft, the worst seat in the house. This is the only identifiable Norden bombsight building still standing in the United States.

Also see . . .  Norden bombsight -- Wikipedia. Postwar analysis placed the overall accuracy of daylight precision attacks with the Norden at about the same level as radar bombing efforts. The 8th Air Force put 31.8% of its bombs within 300 metres (1,000 ft) from an average altitude of 6,400 metres (21,000 ft), the 15th Air Force averaged 30.78% from 6,200 metres (20,500 ft), and the 20th Air Force against Japan averaged 31% from 5,000 metres (16,500 ft).
