Misawa, Japan 11:20 a.m. Near Misawa, Japan, USAF Lt. David Conant Brigham is flying a T-6 target plane on a practice intercept mission for two F-84s. The first F-84 overtakes him at 6,000 feet when the T-6 pilot notices a small disc gaining on the interceptor. The UFO curves toward the F-84, decelerates rapidly, then flips on edge in a 90° bank. It flies between the two aircraft, pulls away, flips again, passes the F-84, crosses in front, and accelerates out of sight in a near vertical climb. Both pilots notice the object, which comes within 30–50 feet of the T-6. The pilot estimates it is only 8 inches in diameter. There is a ripple around the edge.
