At 16102 on 31 Dec 56 an F-86D pilot flying in the G uam range holding pattern sighted an unidentified blinking white li^rt. Following is a copy of the unclassified message forwarded from Commander, 7th Air Force (Advanced), G uam, Marianas Islands, as a result of the sighting: "The following report submitted in accordance with paragraph 7, AFR 200-2, dated 12 Aug 1954 and FEAF Supplement 1 dated 30 March 1956.

P ilot turned with the object and descended so azimuth and elevation was not discernible. D. The object came in from a westerly heading and pilot, thinking it was a ' B-47, turned down and into the object. The object proceeded to turn with : the aircraft. P ilot began to get suspicious of object when he was unable ! to close with it and it continued to turn with him on the tun.. The pilot knew there were no other fighters airborne at the time and other aircraft stationed in the vicinity could not turn outside the F-86D's turning radius. The object passed between the interceptor and the city of Agana, G uam, and at this time no silhouette was seen. The object proceedec south for approximately 10 miles at the pilot1 s altitude (20,000 MSI) then it climbed to about 30,000 MSL and came directly over interceptor. P ilot turned aircraft to keep it in sight and it started circling him. The interceptor was placed in afterburner and turned into the object trying to head it off. It continued to turn around aircraft and he was unable to gain on it or close with it. Then it proceeded west at aircraft altitude ‘ and returned over fighter at 10 to 15,000 feet high. P ilot again turned to keep it in sight and it circled fighter again. At this time pilot hadtc break off and return to Andersen Air Force Base due to low fuel remaining. E.

Since the U FO B was similar to sightings of weather balloons, 7th Air Force (Adv) was advised to check on any lighted balloons that might have been released at a time to correspond with the sighting. Confirmation was received that a lighted balloon had been launched at 1432Z 31 Dec 56 by the U . S. Weather Bureau at the U . S. Navy Communications Station (13°13’N - 144°50'E). The balloon was last tracked five (5) miles west of the station at 13°33’N - 144C46'E, altitude 20,000 feet at 15002. The observing pilot was again questioned and he stated that he did not believe that the U FO B was a weather balloon because the U FO B maneuvered with the F-86D and accel­ erated past his aircraft. 3.

The check on the 1432Z and had ascended to limited weather balloon showed that it was launched at 20,000 feet at 1500Z. It was lost from view at that time It’s ascension rate was somewhat slower than standard. Normally a weather balloon would be near the 27,500 foot level twenty-eight (28) minutes after launching. 5. If the weather balloon had ascended normally, it would have been much higher than the altitude of the reported sighting. If the balloon had malfunctioned and leveled off or descended, it could possibly explain the reported U FO B. ALAN G .
