I was watching a TV show on the Blue Angels. It was there first airshow ever. It was 1953 and the planes were taking off from an airstrip. In the background in this color video about 20° up and a maybe 5 miles away are two glowing silver saucer objects circling each other in an orbit maybe a mile across. Motion of both objects is clear and they are very distinct from the darker planes of the Blue Angels and the other aircraft visible on the ground and flying by.
