On July 1, the Soviet Union shot down a U.S. Air Force RB - 47 airplane, which was on a proposed mission from the United Kingdom near the northern borders of Norway and the Soviet Union and over the Barents Sea, and rescued two of the six crew members. The two survivors were Captain John B. McKone and Captain Freeman Bruce Olmstead. President Eisenhower discussed his initial reaction to a report that the Soviets had shot down the plane in a telephone conversation with Secretary of State Herter on July 11
