Alto (Tennessee) — April 5, 1966 (2400)
Two civilian men stopped to watch an object hovering above a swamp, tried to follow it, but it flew away. They observed that animals (cows, dogs, horses) were restless in all the areas that the object crossed. A photographic reconstitution by the U.S. Air Force showed an oval object, 30 m long, flying at 5 m altitude, between a high-tension line and a row of trees. (Atic)
