May 21, 1966; Willow Grove, Pennsylvania
3:15 p.m. EDT. This one was personally checked by Dr. James E. McDonald, (listed as Case #5)  a close-range airborne sighting of a domed-disc, seen under midday conditions by two observers. One of them, William C. Powell, of Radnor, Pa., was a pilot with 18,000 logged flight hours. In a light plane encountered a bright-red disc with dome on top at 4,500 feet. Object first spotted as it apparently followed an outbound flight of Navy jets from Willow Grove NAS then made a sharp (non-banking) turn and approached his plane on a near-collision course, passing below their starboard wing about 100 yards away, and disappeared behind the plane. They both got a good look at the object. It was circular in plan form and had no wings or visible means of propulsion, both witnesses emphasized to McDonald in interviews. The upper domed portion they described as "porcelain-white", while the lower discoid portion was bright red.. It was slightly below their altitude as it passed on their right, and Powell pointed out that it was entirely solid, for it obscured the distant horizon areas.
