Sighting of Unusual Phenomenon Near Iran/USSR Border

Summary

On the night of June 17, 1966, a pilot reported an unusual phenomenon while flying near the border between Iran and the former Soviet Union. As he approached Tehran airport, he observed a bright sphere suddenly appearing on the horizon. The light was as intense as midday, and the sphere grew in size while remaining on the horizon. The pilot estimated the sphere to be at around 18,000 feet and located deep within Soviet airspace. The phenomenon remained visible for about five minutes, and another aircraft also observed it. After landing, they discovered that the phenomenon had not been seen from the ground, except possibly in the final moments, when the light had dimmed so much it was nearly invisible.

The CIA report, classified under a specific code, details the pilot's experience, including location, time, and weather conditions. Despite the pilot's observations, the report does not offer a clear explanation. The sphere showed no lateral movement, suggesting it was stationary or slowly ascending. The weather was ideal, with clear skies and unlimited visibility. The pilot concluded the phenomenon was not an aircraft, rocket, or any known object. Although no definitive conclusion was reached, the report reflects the CIA's interest in unexplained aerial phenomena during the Cold War.
