On or during May 30, 1952, at or near SEOf Japan 34DEG15N 139DEG30E, Japan, the source reports the following sequence: O. (CLASSIFICATION) Intelligence Office 61st Troop Carrier Group, Heavy, APO 704 30 May 1952 Crew Members, C-54 # 42-72152A 14th Troop Carrier Sqdn, APO 704 SUBJECT: UNIDENTIFIED FLY OBJECTS, sighted 16 Jan 52. On 30 May 52, the pilot, co-pilot and engineer of C-54 type aircraft # 42-72152A, 61st Troop Carrier Group, Heavy, APO 704, flying on a course of 190°, at altitude of 8,500ft, observed unidentified aerial object between 1900 and 1930 hours, that date, at approx 34°15'N - 139°30'E. Three crew members agree object was round, dark and that it hovered. The co-pilot and engineer, observing object from five to seven minutes, agree that object disappeared rapidly to the west, that no exhaust flames were visible, no means of propulsion ascertainable, and that object was unfamiliar and dissimilar to any aircraft known to them. Pilot, 1st Lt Arblaster, is 29 yrs of age, has 1,929 flying hre, states he frequently observes odd-appearing cloud formations, believes most unidentified aerial sightings are imaginative, and apparently does not attach any importance to reports concerning unidentified flying objects. (Intel. However, pilot probably sincere in his evaluation of incident since he only glanced at object, whereas other members witnessed object from five to seven minutes.) (See inclosed statement) Co-Pilot, Captain Leet, is 36 years of age, has 2,328 flying hours, states he, too, frequently observes odd-appearing cloud formations; insists subject object not cloud. Engineer, T/Sgt Roe, is 30 yrs of age, has 231 flying hrs, conscientious to an average degree. Intel Officer believes report significant since the two crew members who observed object appreciable length of time convinced object not cloud nor balloon. The apparent speed of travel was probably due to shifting light conditions as the aircraft turned into the sun. No instance of a balloon burning in the air has over been reported in this theater. AIR INTELLIGENCE INFORMATION REPORT 61st Trp O-r Tp, Heavy 14th Trp Car 3d, Heavy, AFO 704 IR-4-52 PAGE __ OF __ PAGES STATEMENT "On 29th of May 1952, climbing to 3,500 feet, enroute to Shina Range, on a heading of 190 degrees, at approximately 1925 hours, the co-pilot of my crew remarked that he saw an odd shape in the sky at about 4 o'clock. "It was flying the aircraft and raised up out of the left seat to get a look at what the co-pilot offered. It was approximately 60 to 70 miles from us reaching to about 15,000 feet. "Since I was satisfied that is was only another cloud formation, I did not deem it necessary to contact a GOI station and busied myself with flying duties. "I have enclosed a sketch of phenomena observed." "I hereby certify that I have made the above statement, which I have re- read for accuracy, in the 61st Troop Carrier Group Intelligence Office, AFO 704, this 7th day of June 1952." /s/ Robert J.
