During the closing eighteen months of World War II Allied aviators logged dozens of encounters with self-luminous spheres that shadowed bombers and night-fighters yet never fired a shot. Combat reports quickly dubbed the objects "foo fighters," a borrowing from radar-observer Donald J. Meiers's Smokey Stover catch-phrase. Intelligence files show the phenomenon spanned both European and Pacific theatres and vanished as abruptly as it appeared once hostilities ended.1

Intelligence assessment
At the time Allied analysts weighed three prevailing hypotheses: high-performance German ordnance, electrostatic phenomena akin to St Elmo's fire, or misperceived astronomical reflections.
Captured Luftwaffe personnel denied any such weapon, and post-war U.S. Naval Research Laboratory modelling showed observed manoeuvres exceeded the thrust–weight envelope of the Me-163 or V-2.
The Robertson Panel ultimately filed foo-fighter sightings as unidentified but non-threatening, noting the absence of aggressive action and the objects' disappearance after August 1945.45
