The flight was made to gain photo intelligence before the scheduled opening of an EastWest summit conference, which had been scheduled in Paris, 15 days later. Captain Francis Gary Powers had bailed out of his aircraft and was captured after parachuting down onto Russian soil. Four days after Powers disappeared, the Eisenhower Administration had NASA issue a very detailed press release noting that an aircraft had "gone missing" north of Turkey. It speculated that the pilot might have fallen unconscious while the autopilot was still engaged, and falsely claimed that "the pilot reported over the emergency frequency that he was experiencing oxygen difficulties."
