Chorwon Korea reported disc saucer observation — May 22, 1952

On or during May 22, 1952, at or near Chorwon Korea, Korea, the source reports the following sequence: BRIEF SUMMARY OF SIGHTING: Sighted by T-34 and visually from an A/T site at Chorwon (middle of Korea at 38° parallel) From maneuvers. Point at which object moved to fade DOWNGRADED AT 12 YEAR INTERVALS The object stopped falling at about 2000 feet and went straight back up to about 3000 to 4000 feet. The object started to head toward the East for about one half mile, then it stopped and reversed its course and headed back to the Northeast in a smooth flight at a speed of about 100 to 150 miles per hour. I thought a helicopter was hovering there with a light on one side and had turned that side to me. It stopped getting larger at about 2600 feet altitude and it took the form of a disc. It moved a ways and changed direction. There appears to be a partially redacted description of an observation, with the text indicating that the object "could still hear to 'From the time it first started climbing until it disappeared took approximately three to four seconds". The text of the document is as follows: could still hear to 'From the time it first started climbing until it disappeared took approximately three to four seconds.
