🇺🇸 USAF — Project Blue Book
In September 1954, two U.S. pilots in Korea reported observing two white or silver objects that remained stationary in the sky for at least 10 minutes. The aircraft were on an intercept mission and, according to records, the objects were not detected by ground radar. The pilots described the objects as being at a great height, around 59,000 feet, and silent. Despite performing maneuvers to approach them, the objects did not move or disappear. Official reports considered the possibility of weather balloons, but no definitive confirmation was made. The lack of photographs and the inability to intercept the objects add mystery to this case.
The exact location of the sighting was northeast of Seoul, about 15 nautical miles from Kimpo Airport. The pilots, Vernon Hesterman and Richard McKibben, were in F-86F aircraft when they observed the objects. Weather conditions were favorable and the pilots were experienced, which increases the credibility of the testimony. Despite recording details such as altitude, direction, and duration of the sighting, there was no conclusive explanation. The official report classified it as "possibly balloon," but did not rule out the possibility of something unknown. This case is part of a series of sightings during the Korean War that remain unresolved.
