🇺🇸 USAF — Project Blue Book
In December 1957, a dozen observers, including USAF personnel, reported the presence of an unidentified object over Hokkaido, Japan. The phenomenon was visually observed and detected by radar, with tracking lasting nearly two hours. The object appeared as a very bright light in the south-west sky, and several witnesses used binoculars to observe it in detail. Two aircraft were scrambled to intercept it, but they could not close in. Two to three days later, a blurry photograph of a white light was taken, presumed to represent the same object. Although Venus was considered a possibility, later analyses did not confirm this hypothesis. The nature of the object remains a mystery, with data inconsistencies and a photograph that does not clearly match the visual description.
