Agana, Guam: F-86D pilot Ted Brunson circled by round white object he cannot close on

At 2:10 a.m. on January 1, 1957, USAF 1st Lt. Ted Brunson was piloting an F-86D jet interceptor over Guam when he observed a round, white object flying beneath his aircraft. As he attempted to close with it, the object kept turning with him, always staying on the outside of his turn; it passed between his interceptor and the city of Agana, but he saw no silhouette, only a maneuvering light. The object headed south for about 10 miles at his altitude of roughly 20,000 feet, climbed to about 30,000 feet, moved directly over his aircraft and began circling him. Brunson engaged afterburner and turned into the object to head it off, but it continued circling and he could not gain on it. The object then moved west, doubled back and passed over the fighter again 10,000 to 15,000 feet above him, circling him once more when he turned to keep it in sight. With fuel running low, Brunson broke off and returned to Andersen Air Force Base. The entry cites Sparks's list of Blue Book unknowns (p. 249) and Loren E. Gross's history of November to December 1956 (pp. 64 to 65). 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.
