The Duplex was used in a secret U.S. Air Force project, code named Genetrix, in early 1956. Under the guise of a meteorological experiment, the Air Force launched more than 500 balloons to float over the Soviet Union. Few provided useful photographs. Many were shot down or landed in Soviet bloc countries. The high-altitude Lockheed U-2 took over this type of reconnaissance later that year. The Duplex was developed by the Boston University Optical Research Lab. Its two 6-inch metrogon lenses produced an overlapping field of view.
