As anyone who has read a UFO book knows, the name ‘foo fighters’ was given to the balls of light that appeared to tail Allied bombers over Europe during WWII.
The lights were a source of some concern for pilots, but were little more than a distraction for their commanders once it became clear that they weren’t a direct threat to aircraft. It’s generally thought that at least some of the foo fighters were a kind of flak or chaff. (As an aside, one of those who questioned pilots about the lights was the Goon Show and Potty Time’s Michael Bentine, then in RAF Intelligence, who took a keen interest in fortean phenomena throughout his life).
It’s generally thought that the name is a collision of ‘feu’, the French for fire, and ‘where there’s foo, there’s fire’ the catchphrase of Smokey Stover (above), a fireman in a popular American comic strip.
But there may be another meaning to the name: ‘foo’ might be ‘feu’, fire, but it could also be ‘fou’, meaning folly or madness (as in ‘amour fou’), or even ‘faux’, meaning ‘false’. Any of these words would appropriately describe these enigmatic, playful and ultimately deceptive lights.
Just a thought.
