U.S. Air Force Analysis of Flying Objects in the United States, 1-100

At 2045 hours, 6 July 47, Staff Sergeant Livingston's attention was called by a neighbor (a Mr. Herman M. Sockwell) to witness some "flying discs." The objects appeared in the west of Birmingham and were traveling southeast. They appeared to be 2000 above the horizon at a high angle at an unestimated distance away. They were approximately 2 ft in diameter, and round. They produced a dim glow of light and were traveling at an estimated speed of 500 to 600 MPH. The object (or objects) appeared to be traveling in a definite arc rather than straight, and as soon as one was out of sight, another would appear behind it but not always in the same path. One seemed to come straight up. The view of its source was obstructed by a nearby house but upon reaching the altitude of approximately 2000 ft it started off in the same direction as the others. Sergeant Livingston says that he did not at any time see more than one object at a time, and the it could have been one object it was his personal opinion that there were seven to ten objects. The discs were silent and appeared composed of a single light.
