(Donald J. Meiers, teniente del 41º escuadrón de caza nocturna de los Estados Unidos, es el primer piloto conocido que utilizó el término “Foo-fighters”)
“Foo fighter” is a name given to a small, round flying object which are best known for following Allied bombers during the latter phases of WWII. Sometimes they would appear singularly but more often in groups, often flying in formation. By day they appeared to be small metallic globes. By night they glowed with various colors. These objects attempted to approach Allied bombers closely which scared the bomber crews who assumed they were hostile and might explode.
