Project Blue Book Case #9031. On August 10, 1964, an unidentified object was reported over Wake Island — a tiny coral atoll in the central Pacific Ocean, approximately 2,300 miles west of Honolulu. Wake Island was a U.S. military installation with a runway that served as a refueling stop for trans-Pacific flights.
Wake Island's extreme isolation made any unidentified aerial object particularly noteworthy. The nearest major landmass was over a thousand miles away, and air traffic to the island consisted exclusively of scheduled military and civilian refueling stops — all meticulously logged. There was essentially no "casual" air traffic that might be misidentified.
The atoll had been the site of a heroic Marine defense against Japanese invasion in December 1941, and it continued to serve military purposes throughout the Cold War. Its strategic position along Pacific air routes made it a natural waypoint for military transport and patrol aircraft.
The object observed over Wake could not be correlated with any scheduled flight arrival, departure, or overflight. The island's comprehensive flight logs and the virtual absence of unscheduled traffic made the failure to identify the object especially puzzling.
The case was classified "Unknown" — one of the most geographically isolated cases in the Blue Book files.
