Incident #59 Sighting Report — Midway Island to Oahu, 12 September 1947

This document details a sighting of an unidentified object by a Pan American flight crew on September 12, 1947, while flying from Midway Island to Oahu. The report, compiled by the District Intelligence Officer of the 14th Naval District, describes the observation of an intense white light at approximately 0558 GCT. The pilots, who were experienced aviators, reported that the object appeared at 9,500 feet and traveled at an estimated 1,000 knots. The object initially appeared as a single white light, but after the pilots switched from automatic to manual control, the object veered to a course of 109 degrees and split into two parts, which then assumed a reddish hue. The pilots noted that the object maintained a constant altitude throughout the six-second observation before disappearing. The report includes a formal evaluation by the Air Technical Intelligence Center (ATIC), which concluded that the object was likely a fireball. The ATIC assessment suggests that fireballs are known to change course abruptly when splitting and that the reported color change and flight characteristics are consistent with this natural phenomenon. The document includes a check-list of the incident, correspondence between naval intelligence offices, and an index of incidents from the Project Grudge report, where this event is categorized under astronomical phenomena.
