EDIT: That's right Dion, the pilots (Japanese I think) called the UFO's 'foo fighters'. They themselves were not 'foo fighters'.

Better definition.

The objects were dubbed "foo fighters." because of a popular comic strip at the time, Smoky Stover. Smoky was fond of saying "Where there's foo there's fire" and the objects seem to be fiery, rounded shapes.
