It's interesting to learn that there were orders to handle the device with the utmost secrecy within the US air force, while the Germans already had the blueprints: > But U.S. intelligence experts received a shock when they interrogated Luftwaffe personnel: The Germans had known the bombsight’s secrets even before the war, thanks to a spy at Norden. > Herman W. Lang, a naturalized U.S. citizen, had been employed as a draftsman and inspector at the Norden factory during the 1930s. American authorities didn’t know that he had served as Nazi stormtrooper in Germany between 1923 and 1927. Recruited as a member of the Duquesne Spy Ring, in 1938 Lang gained access to the plans for the bombsight and hand-copied the blueprints, which were then smuggled to Germany via ocean liner.
