Datasaab affair
The Datasaab affair (Swedish: Datasaabaffären) was a political and export-control controversy involving the transfer of technology from Sweden to the Soviet Union during the Cold War. The affair centered on the sale of the TERCAS (Terminal and En Route Control Automated System) air traffic control system by the Swedish company Stansaab to the Soviet state organization Elektronorgtechnica in the mid-1970s.
