Project 10073 Record Card and Air Intelligence Information Report — Sighting near Kisalon, Mindanao, 17 May 1958

This document comprises a Project 10073 record card and an Air Intelligence Information Report (IR-92-58) regarding a sighting of an unidentified flying object near Kisalon, Mindanao, Philippines, on 17 May 1958. The primary witness, a Jesuit priest, reported observing a very bright, silvery-bluish, round object at approximately 8:15 PM local time. The witness described the object as being more brilliant than Venus, emitting sharp rays, and moving in a path that included a pause followed by a rapid descent, covering a 90-degree arc in less than one minute before disappearing behind Paliapan Mountain Head. The report includes a detailed account extracted from a letter written by the witness to the Director of the Manila Observatory. The Office of the Air Attache in Manila, specifically Captain James O. O'Neal, conducted an investigation into the incident. Captain O'Neal interviewed the witness in February 1959 and concluded that the individual was a qualified observer. The Armed Forces of the Philippines (AFP) also conducted a ground search of the area but found no physical debris. The official conclusion reached by the Air Intelligence office was that the object was an astronomical phenomenon, specifically a meteor, with the observed path fluctuations attributed to atmospheric conditions. The document also contains speculative commentary from the preparing officer regarding the possibility of Russian re-entry techniques, suggesting that a rocket with properly designed fins could produce the observed flight pattern. The report is marked as unclassified and was distributed to PACAF, AF13, and COMNAVPHIL.
