PROJECT 10073 RECORD CARD — Cockburn Harbor, South Caicos Island, 29 May 1958

This document contains a Project 10073 record card and associated correspondence regarding an unidentified aerial phenomenon observed on May 29, 1958, near Cockburn Harbor, South Caicos Island. The sighting was reported by the crew of the CGC GENTIAN, who observed a bright amber fireball with a tail extending vertically upwards. The object was visible for 10 to 15 seconds and descended slowly and vertically until it disappeared behind the island. The report notes that the entire horizon was brightly illuminated during the event. Weather conditions at the time were reported as cloudy with slight seas and an air temperature of 82 degrees. Following the initial report, the Air Technical Intelligence Center (ATIC) requested geographic coordinates for Cockburn Harbor from the 7th Coast Guard District in Miami, which were subsequently provided as 21 degrees 29 minutes North, 71 degrees 31 minutes West. The official conclusion reached by the investigating authorities was that the object was likely a flare originating from either an aircraft, naval units in the area, or a local ground installation. The case was ultimately classified as having insufficient data for a definitive evaluation, with an investigator's note stating that the report contained very limited information.
