WW2 Mystery: Foo Fighters (2021)

The Foo Fighters, the mysterious glowing orbs of World War II that later gave their name to a band, first appeared on a much bigger stage - the battle-torn skies over Europe. Glowing balls ducked and dodged military flight formations at high speed, under apparent intelligent control. Some were even photographed or filmed. Military chiefs rushed to explain the craft in official reports as Nazi or Japanese secret weapons. At the end of the conflict the mysterious interceptor sightings faded away, to be replaced with their modern counterpart: the UFO.
