In 1956 my father, John J. Glennon (Librarian for the what is now the American Institute of Aeronautics and Astronautics), was one of the few fluent Russian speakers in the US, as I was given to understand. He was recruited by the FBI's New York Office by John Connolly to work with the CIA. In November of 1956 my father traveled to Russia after a thorough background check of friends, family, etc. I understood that his assignment was to find out what was the status of aircraft (not sure what else). \He spent three weeks there.
Question: does anyone know more about the context for that trip, and about his project? He never spoke of this assignment. Does anyone have any information about John J. Glennon's visit to the USSR, or the name he used in Moscow?
He was driven around of course and attended a high level gathering on November 7, 1956. He did take 33mm videos, which we still have.
