PROJECT 10073 RECORD CARD - Kimpo AB, Korea - 18 September 1954

This document is an Air Intelligence Information Report regarding an Unidentified Aerial Phenomenon (UAP) sighting at Kimpo Air Force Base (K-14), Korea, on 18-19 September 1954. Five military personnel, including weather forecasters and tower controllers, observed a bright, round object for approximately 11 to 13 minutes. The witnesses described the object as appearing like a star but significantly brighter, with a glare resembling sunlight reflecting off polished aluminum. The object was initially spotted at an elevation of 50 degrees and an azimuth of 175 degrees. It remained relatively stationary before moving in a westerly direction, eventually disappearing behind clouds at an azimuth of 180 degrees. The observers utilized 7x50 power binoculars to track the object, noting that it appeared to be the size of a pinhead at arm's length and lacked any streamers or tail. The weather station at K-14 confirmed that a weather balloon was released at 0600I on 19 September, but the intelligence assessment concluded that the balloon's trajectory did not match the observed object's position. Furthermore, the local radar station reported no corresponding plots in the area during the time of the sighting. Intelligence officers ruled out astronomical bodies such as the star Rigel or Sirius, noting the object's brightness and motion. The final assessment by the 4th Fighter Interceptor Group Intelligence office stated that there was apparently no explanation for the sighting, and the reliability of the five witnesses was considered good.
