Having been a UFO fanatic my entire life, I took a simple phrase from a book I was reading at the time, Above Top Secret, which was a collection of UFO sighting reports and accounts from the military dating back to the early forties. In a chapter about unidentified craft over Europe and the Pacific during World War II, I found a term that the military used as a nickname for these unexplained glowing balls of light and thought it was just mysterious enough for me. Not only did it sound like a group of people, it almost sounded like a gang: Foo Fighters.
