For much of World War II, this was among the most secure facilities on base. Inside are five closet-sized walk-in safes, where the Norden bombsights were stored, and a work bench area. These bombsights were complicated analog computers with target sights, which were used to calculate the proper moment to drop bombs to hit their targets, with consideration to the complexities of elevation, wind direction, speed, and other factors. The bombsights had more than 2,300 parts, and were kept here for security purposes—never left on the aircraft. Unknown to the Allies, though, the specs for the sights had been leaked to the Germans by a spy inside the Norden company as early as 1938. But the sights weren’t very accurate anyways. This building has been restored by the airfield, and may be visited by contacting the Wendover Historic Airfield Museum.
