🇺🇸 USAF — Project Blue Book
In October 1952, two U.S. Air Force pilots reported an unidentified object while on a mission over Korea. The object, described as a metallic silver sphere approximately 25 feet in diameter, was observed at an altitude of around 6,000 feet. The pilots noted that the object changed speed, stopped, and hovered before accelerating rapidly toward the southeast at an estimated speed of 800 miles per hour. No sound or propulsion signs were observed, which generated confusion and surprise among the observers. The detailed description and distance and size estimates, based on comparisons with known objects, add credibility to the observation. Although a weather balloon was considered as a possibility, the pilots dismissed this explanation due to the object's solid and perfectly round appearance.
Air intelligence reports documented this observation as part of an effort to understand unidentified aerial phenomena. The pilots, experienced in combat, accurately described the object's behavior, suggesting their testimony is reliable. Despite favorable weather conditions and no optical interference, the object showed no aerodynamic features or smoke trails. This observation, along with similar ones in the region, contributed to a growing interest in UFO reports during the Korean War.
