Various news articles were published between 1944 and 1945, regarding "The Foo Fighters" and the mystery of the weapons in the sky

Air warfare was a major component in World War II. Germany and Japan depended on air warfare that was closely integrated with land and naval forces. Britain and the U.S. were able to build bombers that could give the ability to win air superiority over battlefields, aiding the ground troops. Since air warfare was such a large aspect, new developments in the assembly and manufacturing led to confusion and the idea of 'secret weapons'. The term foo fighter was used by the Allies to describe unidentified objects seen in the skies, that were thought to be secret weapons employed by the enemy.
