This document is a military sighting report filed by the 2230th Air Force Reserve Training Center at Floyd Bennett Naval Air Station in Brooklyn, New York. It details an Unidentified Aerial Phenomena (UAP) incident that occurred on September 24, 1953, at 1330Z. Two witnesses, a 13-year-old student and a 45-year-old police officer, reported observing a single, silver, round object in the sky over Prospect Park, Brooklyn. The witnesses, who were watching pigeons at the time, described the object as appearing similar to a star or a balloon. The object was observed for approximately thirty minutes, during which time it moved in a straight line from a 45-degree angle in the west to a 45-degree angle in the east, without performing any maneuvers. The weather was reported as clear. The report notes that there was no radar contact and no photographic evidence. The investigation, conducted by the Air Technical Intelligence Center at Wright-Patterson Air Force Base, concluded that the object was at such an extreme altitude that it could have been almost any type of airborne object.
