Project 10073 Record Card — Bohol Island, Philippine Islands, 9 May 1958

On May 9, 1958, at approximately 0305Z, a pilot flying for Philippine Air Lines (PAL) observed an unidentified object over Bohol Island in the Philippines. The pilot reported that the object was falling from the sky, spinning, and leaving a trail of smoke. The object appeared to have a metallic surface that reflected the sun's brightness. The observation lasted for approximately 90 seconds before the object entered a thick cloud layer and was lost from sight. The pilot estimated the altitude of the object to be 10,000 feet or less. The incident was reported via a CIRVIS (Communication Instructions for Reporting Vital Intelligence Sightings) report. Following the sighting, a local investigation was conducted, which failed to identify any missing aircraft. The Weather Bureau confirmed that there were no balloons or other equipment in the area that could account for the sighting. The official Project 10073 record card classifies the incident as 'UNIDENTIFIED'. Handwritten annotations on the document indicate that the report provided insufficient data, noting a lack of specific azimuth, elevation, or heading information from the pilot, and the absence of radar confirmation.
