November 15, 1952 1307 GMT Pyongyang, North Korea
This case is presented in Air Intelligence Information Report No. 52-350 dated 28 November 1952. The sighting took place from a T-6 aircraft over the central sector of the friendly main line of resistance. Following are excerpts from this report:
"At the time cited, Lt. (Layten S.) Bass was flying in the vicinity of CT795418 at 130 miles per hour indicated air speed, 10,500 feet, indicated altitude and in a northerly direction. The weather conditions were clear, with visibility from 15 to 20 miles.

The sun at this time of day is in a south, southwesterly position from the incident area. Winds at 10,000 feet were generally from 240 degrees with velocities up to 20 miles per hour.

"Lt. Bass first noted the unidentified object moving north, apparently close to the terrain.... The object initially dismissed by Lt. Bass as an aircraft, moved north approximately five (5) miles and then turned south and gained altitude....When the T-6 aircraft was at point #2 as indicated in the map overlay, Lt. Bass again sighted the object and identified it as not being an aircraft. This sighting was to the right of the T-6, at an estimated 100-200 yards. Lt. Bass described it as spherical in shape, silver in color and approximately 8-10 feet in diameter He further described the object as lacking any visable (sic) means of propulsion and having no protrusions of any sort. The surface was smooth. There was no audible sound.

When Lt. Bass saw the object, which was moving at approximately the same speed as the aircraft, he turned the aircraft towards it slightly at which time the object headed south and began climbing at a high rate of speed, turning into a left orbit around the aircraft (note 1). Lt. Bass called the object to the attention of Lt. Barnard who saw it as it went into it's left-hand orbit. (Lt. Barnard estimated the closest distance to the object as being from 500 to 1000 yards).

"Lt. Barnard's description of the object was that it was a silver spherical object, approximately the size of a man's thumb nail held at extended arms length, (note 2). He further described the object as "shimmering" and having a "halo" which surrounded the object. The halo was only a hairline thickness. He further stated that the shimmering effect appeared to be more apparent when the object was between the aircraft and the general direction of the sun. The object appeared to Lt. Barnard as being darker at the edges, as a translucent sphere would appear when held up to a light.

Other details were given. "The object was viewed against various colored backgrounds, the dark terrain, and blue sky and white clouds. It remained constant as to shape, size, and color." "Both sources state that the general motion of the object was steady and gave the impression of controlled flight. They stated that it did not appear to be moving on the motion of air current." "The pilot had flown 54 missions in this theater and the observer had flown 48 missions."

The preparing officer (1st Lt. James F. Power) considered both observers to be "compitent (sic) observers and sightings reported by them are considered reliable." There was no ground radar contact other than that of the T-6 aircraft. He also stated that the object "could have been (a) 350 gram (white latex) weather balloon" released from the Army's 1st Artillery Observation Battalion, a light plane unit located at Tokchong, CS3089, southwest of the location where this UFO was sighted. A balloon of this size was launched at 1257I on 15 November about 50 minutes earlier. However, Brigadier General Charles Y. Banfill, Deputy for Intelligence stated: "The 350 gram balloon released 50 minutes previous to the sighting would not be expected to be at any visible altitude at the time of the incident unless it were leaking, (which would preclude the rapid climb described). There previously have been a number of unidentified sightings in the CT and DT grid areas of Korea. Of these, at least 5 sightings have tentatively been identified as enemy balloons. Vectoring an aircraft on a free balloon is actually difficult, and false impressions of rapid movement can easily be made. From the available information it appears that the object was probably a balloon, and possibly one launched by frontline enemy troops." (See Appendix 1for generally representative sizes and weights of U.S. balloons for comparison)

Notes:
1. The reported behavior of the UFO is similar to that described above for October 16, 1952, less than one month before! This apparent reactivity by the UFO is intriguing.
2. This is approximately equivalent to an angle of 1.8 degrees arc.
