Foo fighters are electroballs that follow moving vehicles, generally metallic planes in flight, being reported mainly, since the Second World War by different sides.
In the bible it was identified as the angel Saint Raphael, the one who follows pilgrims.
CAUSE OF APPEARANCE
If a vehicle charged with static electricity, such as an airplane that had crossed a thundercloud, approaches an electroball in which the opposite electrical charge predominates, it will cause it to be attracted and follow the vehicle, often at a stable distance.
It is kept at a distance because the outer layer of the electroball, with the charge of the same sign as the vehicle, is repelled more than the core is attracted because it is a little closer.
This can be verified with the following analogy with magnets in the following video, since the magnetic forces in the plane behave the same as the electrical ones.
