 Thus, some of the configuration details of SAMOS were decided less by engineering logic than by the need to camouflage GAMBIT and thus, in theory, a GAMBIT could be launched without alerting many people to its real nature.Problems relative to tracking networks, communications, and recovery were resolved with the decision in late February 1961 to use Johnston Island as the film capsule descent and recovery zone for the program.On July 10, 1961 work was initiated on four buildings of the Johnston Island Recovery Operations Center for the National Reconnaissance Office.
