Somne one once mentioned that the name is crap ... This is a peice of information to all the jerks who called it crap ... source : http://en.wikipedia.org/wiki/Foo_fighter The term foo fighter was used by Allied aircraft pilots in World War II to describe various UFOs or mysterious aerial phenomena seen in the skies over Europe and the Pacific theatre. Contemporary witnesses often assumed that the foo fighters were secret weapons employed by the enemy. Despite these fears, foo fighters (whatever they might have been) were apparently never reported to have harmed or tried to harm anyone. Though usually thought of as blobs of light or fire, several different types of reported phenomena were classed as "foo fighters".
