Kimpo Air Base, Korea: RAAF flight sergeants see coin-shaped object spin and tumble

At 8:42 a.m. on June 6, 1952, Flight Sgt. Kenneth Dudley Smith of the 77th RAAF Squadron at Kimpo Air Base (now Gimpo International Airport) in Seoul, Korea, observed a dull silver object shaped like a coin and about 50–60 feet long. For 4 minutes it performed spinning and tumbling maneuvers at 345 mph. Flight Sgt. Kenneth Fawner also saw the object, for 30 seconds. The case is documented in Project Blue Book files and listed by Brad Sparks. The account follows the entry in George M. Eberhart's chronology UFOs and Intelligence (CUFOS) and the sources cited there; it is not an independent determination by From Beyond Space.
