Project 10073 Record Card and Air Intelligence Information Reports - Northern Kyushu, Japan, 27 October 1952

This document is an Air Intelligence Information Report (IR-6-52) produced by the 527th AC&W Group, dated 3 November 1952, concerning an unidentified aerial phenomenon sighted over Northern Kyushu, Japan, on 27 October 1952. The report compiles statements from multiple personnel stationed at Moji D/F and Seburi-Yama D/F. Witnesses described a star-like object that appeared at an altitude of approximately 20,000 feet, exhibiting a color change from deep orange to pale yellow. The object was observed to disappear and reappear at intervals over a period of 25 minutes before eventually disappearing behind a mountain to the west. The witnesses, including D/F operators and maintenance personnel, consistently reported that the object did not produce any sound, exhaust, or trail. Despite the visual sightings, ground radar stations were unable to detect the object, leading investigators to conclude that it did not perform any erratic maneuvers. The report notes that a rawinsonde balloon was released from Itazuke Air Strip at 1753I on the same evening, which reached a maximum altitude of 57,995 feet and drifted 10-12 miles west of the station. The intelligence assessment suggests that the sightings were likely attributable to a combination of factors, including the weather balloon, searchlights, distant surface vessel lights, or stars. The report emphasizes that no electronic contact was made by ground stations that could confirm the object's identity. The document includes multiple enclosures, such as individual statements from the witnesses and a map of the area. The final assessment, signed by Brigadier General Charles Y. Banfill, suggests that the unidentified object was likely a combination of common phenomena rather than an anomalous craft.
