UFO Sighting Report - Brookville, Long Island, New York - 5 August 1964

This document is a formal report concerning a UFO sighting that occurred on the evening of 5 August 1964 in Brookville, Long Island, New York. The report was prepared in accordance with Air Force Regulation (AFR) 200-2 and forwarded by the Headquarters of the New York Air Defense Sector (NYADS) at McGuire Air Force Base to the Air Force Systems Command (AFSC) Foreign Technology Division (FTD) at Wright-Patterson Air Force Base. The sighting was reported by two individuals residing on Colony Road in Upper Brookville. The witnesses described the object as a star-shaped, orange entity with a tail positioned at a 90-degree angle to its path of flight. The object was observed for approximately three to five minutes as it moved in a straight line before disappearing behind trees. At the time of the observation, the object was noted at 85 degrees above the northern horizon under clear weather conditions. Captain John J. Guilfoyle, the Intelligence Officer for NYADS, investigated the incident. He determined that a weather balloon had been released from John F. Kennedy International Airport at 2330Z on 5 August. Based on the trajectory, it was concluded that this balloon would have traveled eastward into the area where the sighting occurred, and the official assessment is that the reported object was this weather balloon.
