Miami, FloridaApril 1952

On the night of April 5, 1952, an amateur astronomer and his nine-year-old son watched four circular dark objects pass across the face of a nearly full moon near Miami, Florida. The men were lying in hammocks in their yard at 9:15 p.m., looking up at the sky. The first object crossed the moon's lower edge, followed by three others that moved from west to east. The second and fourth objects passed directly across the moon, blocking out about half its visible surface. All four objects were dark and completely invisible except when silhouetted against the moon. The one that crossed the moon's face made the full transit in roughly one second. Its leading edge was sharp and well-defined, though a fuzzy halo surrounded about two-thirds of its circular outline. The objects made no sound and gave off no light of their own.

The amateur astronomer impressed the Air Force interviewer as a capable and credible observer. He was not using his small telescope at the time of the sighting, and he noted that the objects seemed to fly in formation. Because they were outlined only against the moon, he could not judge their actual altitude or size. After the incident, he searched the sky with his telescope but saw nothing else unusual. His son also witnessed one of the objects but described it as an irregular shape rather than circular, though the father's trained eye as an artist was considered more reliable. No one else in the area reported seeing the objects.

The Air Force field report noted that the observer was calm, level-headed, and well above average in intelligence. He had been watching the skies regularly for three or four years hoping to see a "flying saucer," but he was actually disappointed by the sighting because it seemed less spectacular than he expected. The report contains a freehand sketch by the observer and records that there were no other corroborating sightings.

The Air Force concluded the case as unidentified. The file consists of 9 pages as held by the National Archives.
