The term foo fighter was used by Allied aircraft pilots in World War II to describe various unidentified flying objects or mysterious aerial phenomena seen in the skies over both the European and Pacific theaters of operations. They were formally reported from November 1944 onwards.
NAZI UFOsEditAuthor Renato Vesco revived the wartime theory that the foo fighters were a Nazi secret weapon, in his book, Intercept UFO, reprinted in a revised English edition as Man-Made UFOs.
During April 1945, the US Navy began to experiment on visual illusions as experienced by night time aviators. This work began the US Navy's Bureau of Medicine (BUMED) project X-148-AV-4-3. This project pioneered the study of aviators' vertigo and was initiated because a wide variety of anomalous events were being reported by night time aviators.
