Foo fighters: World War II lights before the modern UFO era

Foo fighters were wartime reports of lights or objects near aircraft, long before flying saucers became a public obsession.

Key points

The reports matter because they predate the 1947 flying saucer wave.
Wartime stress, enemy-technology fears, atmospheric effects, and misidentification all shape the record.

Why they remain interesting

Foo fighter reports are useful because they show that unusual aerial reports did not begin with postwar UFO culture. Aircrews described lights, balls, or objects that appeared near aircraft during combat operations. The records are historically important, but they are also difficult: wartime conditions limited documentation, and explanations can include enemy technology anxiety, electrical effects, atmospheric phenomena, or ordinary lights seen under stress.

FAQ

Were foo fighters alien spacecraft?

There is no solid public evidence for that. They are better treated as wartime mystery-light reports.
