Guam F-86D Intercept: 1st Lt. Ted Brunson and Blue Book Unknown 4577

In August 1956 the 41st Fighter-Interceptor Squadron began flying F-86D Sabres from Andersen Air Force Base in northern Guam. It was Andersen's largest unit at the time and was responsible for the air defence of the Marianas. The F-86D was an all-weather interceptor with its own radar. None of the case records name the pilot's squadron, but it is a likely link.

December 31, 1956. At 2:10 a.m. local time, 1st Lt. Ted Brunson was airborne near Agana, the island's capital, at roughly 20,000 feet. Beneath his jet he saw a round object that glowed white, and he moved to close with it. The light turned with him and stayed on the outside of his turn every time. As one early summary put it, the F-86D "was unable to turn as sharply as the object."

Then it passed between his interceptor and the lights of Agana. Brunson looked for a shape against the city glow. He saw only the light, with no silhouette. It headed south for about 10 miles at his altitude. Then it climbed to about 30,000 feet and moved directly over his aircraft. Brunson turned to keep it in sight, and the object began circling him.

He engaged afterburner and turned into it, trying to head it off, but it kept circling and he could not close the distance. The light moved west at his altitude, doubled back and passed over the fighter again. This time it was 10,000 to 15,000 feet above him. Brunson turned again, and again it circled him. About ten minutes in, his fuel ran low, and he broke off and returned to Andersen.

The report reached Air Force intelligence as an AFOIN message, and Project Blue Book filed a record card. The verdict was Unidentified. In 1974 Don Berliner compiled a list of Blue Book Unknowns from Air Force Archives files for the Fund for UFO Research. The case is number 4577 on that list. Brad Sparks catalogued it as Case 1217.

No further analysis appears in the published sources. Nobody mentions radar contact, from the jet or from the ground. There are no photographs. Brunson was the only witness. Even the date is uncertain, with one compiler adding January 1, 1957.

No explanation for the Guam case has been published. Still, a lone white light at night that seems to out-turn an interceptor is a familiar pattern. Skeptics often point to a bright planet or star in cases like this. Such a light is so far away that it always seems to stay outside a pilot's turn.

That was how J. Allen Hynek explained an F-86D chase over Japan in December 1957. His note reads "Definitely Venus." Skeptics would also question the altitude figures, which depend on a pilot judging the distance to a single light in the dark. Supporters see the same figures as proof of real maneuvering. No published check of the bright planets over Guam that morning has turned up.

Brunson later rose to lieutenant colonel. His son, Ty Brunson, commented on the incident in a Guam Pacific Daily News article about the island's long history of UFO reports. In 2021 the Pacific Island Times recalled the chase among Guam's encounters with the unknown. The Guam intercept is still what Blue Book called it. Unidentified.
