Project 10073 Record Card — San Juan, Puerto Rico, 8 April 1962

On April 8, 1962, two separate but likely related aerial sightings were reported near San Juan, Puerto Rico. The first incident occurred at 0353Z, when an air crew reported a green flare approximately 20 miles north-northeast of San Juan. A second report from a Military Air Transport Service (MATS) crew followed at 0400Z, describing a green 'meteorite' at coordinates 1913N 6739W, which was observed climbing to an altitude of 12,000 feet. These reports were transmitted via the CIRVIS (Communication Instructions for Reporting Vital Intelligence Sightings) system to various military commands, including CINCNORAD, the Chief of Staff of the Air Force, and the 72nd Bomber Wing at Ramey Air Force Base. The Air Technical Intelligence Center (ATIC) processed these reports under Project 10073. Following an evaluation of the data, the official conclusion reached by the military was that the sightings were likely related and possessed the characteristics of a meteor observation. Consequently, the event was classified as a 'no threat' to national security. The documentation includes the original record card and the subsequent incoming staff messages confirming the evaluation.
