Oval over Central Korea · South Korea

Investigated by a competent body and left unresolved. The rarest grade, and never awarded by us — only recorded.

The report, as filed

Central Korea. 3:03 p.m. Witnesses: four Marine Corps Captains and pilots of F4U-4B Corsair fighter planes. One 10-20' white or silver oval object made a left-hand orbit at terrific speed for 60 seconds.

Held as-reported from Project Blue Book, United States Air Force. Witness text is preserved verbatim, including its spelling; nothing is edited beyond formatting.
