The Tumbling Disc in Korea (1952)

At 08:42 on 6 June 1952 a flight sergeant at an Air Force base in Korea watched a disc spin and tumble over the field, stop, shoot straight up and vanish into the sun. The Air Force's own statistical study kept it among its twelve best unknowns. This is the record of what was reported, not a verdict on what was over the airfield.

◆ THE SHORT VERSION

  • The Tumbling Disc in Korea (1952) is a reported UAP case in South Korea, 6 June 1952, 08:42.
  • A flight sergeant at an Air Force base in Korea reported a disc that spun and tumbled over the field, stopped, shot straight up and disappeared into the sun, then flew back and forth across it.
  • At one point an F-86 passed between the observer and the object, the Air Force summary says, and a second man watched it manoeuvre near the sun.
  • Project Blue Book Special Report No. 14 kept it among its twelve best unknowns but set it aside because its manoeuvres matched no other report.
  • An intelligence report outside the release places the sighting at Kimpo and names the observer as Flight Sergeant Kenneth Dudley Smith of No. 77 Squadron RAAF.
  • For this case Fractured Realities holds 1 distinct source and 1 corroborating primary document.
  • The archive grades it L0 · SINGLE ACCOUNT — the archive holds one account of it, from a single source.

The object kept changing its mind. At 08:42 on 6 June 1952, the Air Force summary says, a flight sergeant at an Air Force base in Korea watched it fly "in a series of spinning and tumbling actions". It flew level and stopped for a moment. Then it shot straight up, levelled off and tumbled again before changing course and "disappearing into the sun". It came back and was seen "flying back and forth across the sun". At one point an F-86 passed between the observer and the object. He pointed it out to another man, who watched it manoeuvre near the sun.

What is on the record

The released record is Project Blue Book Special Report No. 14, the Battelle Memorial Institute's statistical study of Air Force sighting reports, dated 5 May 1955. The Department of War published the CIA's official record copy as CIA-UAP-015 in its third PURSUE release on 12 June 2026. This sighting is Case VII (Serial 2728.00) in the appendix of twelve "good UNKNOWNS", chosen because each was described well enough to draw. The report strips out every name and place. Its sketch, redrawn from the observer's own, shows a flat disc seven times as wide as it was thick and marked with evenly spaced concentric lines.

Battelle did not explain the case. It set it aside because the shape was disc-like but "the maneuvers performed by the object are unique" among all its unknowns, so it could not help build a model of a flying saucer. The report concluded that no such model could be derived from the data.

An intelligence report on the same sighting survives outside the release. Air Intelligence Information Report 52-139, as transcribed by Project 1947, puts the observer at K-14 Kimpo Air Field. It names him as Flight Sergeant Kenneth Dudley Smith of No. 77 Squadron, Royal Australian Air Force, and the second man as Flight Sergeant Kenneth Fawner. Blue Book's own case file is recorded as missing. The Australian War Memorial records that Smith was killed on operations near Koksan, North Korea, on 8 July 1952.

Why it sits where it does

L0 · SINGLE ACCOUNT. The released document is one study that removes the witness's name, so the record carries no identified witness. The names come from a report the release does not include. A tier measures sourcing, not truth. What tumbled over the airfield is not resolved here.
