AT A GLANCE

A USMC F9F Panther pilot obtained gun camera footage of an unidentified luminous object over Okinawa during the 1952 wave. Ground radar confirmed the contact. The K-20 camera footage was classified and forwarded to Blue Book as one of the program's few authenticated aerial gun camera records.

DECLASSIFIED DETAILS

On August 22, 1952, a US Marine Corps F9F Panther pilot flying a combat patrol over Okinawa observed and locked onto an unidentified luminous object at 50,000+ feet altitude — above the F9F's operational ceiling. The pilot activated his K-20 gun camera and obtained several seconds of footage before the object accelerated beyond his pursuit capability. Ground radar at USMC Air Station Futema tracked the engagement. The gun camera footage was immediately classified upon the aircraft's return and forwarded under special handling to Project Blue Book. The footage reportedly showed a structured luminous object with clear aerodynamic features inconsistent with a balloon or natural phenomenon. Blue Book analysts rated the case 'unidentified' — one of approximately 700 cases that received that classification. The footage was among the most frequently referenced classified motion picture evidence in early Blue Book files, cited alongside the Great Falls and Tremonton films as the most significant motion picture evidence in the program's record.

KEY CHARACTERISTICS
  • K-20 gun camera footage classified
  • 50,000+ foot altitude above aircraft ceiling
  • Ground radar engagement confirmation
  • Blue Book 'unidentified' motion picture classification
  • Comparable to Great Falls and Tremonton films

Yellow Sea — Spherical UAP High-Speed Video

Yellow Sea, East Asia

A classified video captured in 2022 over the Yellow Sea shows a spherical UAP moving at high speed. The footage, described by intelligence officials as among the clearest recorded encounters in the archive, is included in the May 2026 Pentagon release. The object's speed and flight characteristics were assessed as inconsistent with any known aerial platform.

Japan JSDF Radar UAP Detections — Parliamentary Disclosure

Japanese territorial airspace (multiple sectors)

In April 2023, the Japanese government disclosed to its Parliament (the Diet) that the Japan Air Self-Defense Force (JASDF) had recorded multiple unidentified aerial objects detected by radar that could not be identified as any known aircraft or drone. The disclosure followed a formal parliamentary inquiry. Japan's Ministry of Defense established new UAP reporting protocols in 2020 and the 2023 disclosure represented the first formal parliamentary acknowledgment of operational UAP detections.

Korean War UAP Intercepts — USAF Combat Reports

Korean Peninsula and Yellow Sea, Korea

US Air Force and Navy combat pilots filed dozens of formal UAP encounter reports during the Korean War. B-29 bomber crews and fighter pilots described glowing orbs and structured craft performing extreme maneuvers in combat airspace. USAF Far East Air Force (FEAF) officially investigated and filed reports with Project Blue Book at Wright-Patterson AFB. Several cases were classified SECRET and are now available through NARA.
