If you were to describe a UFO how would it ACT not to be confused with how it looks.
for example legend says that when a UFO is near lights flicker or go out. radios or compasses go crazy, UFOs interfere with flight equipment in some way.
some would say that UFOs are magnetic or gyroscopic, others might say that UFOs are radioactive some even say that UFO's use sound to levitate or tractor beams to pull in victims. can they open vortex portals or something.
I'm looking to make a list of UFO characteristics based on their mythology.
all I'm asking is what do UFOs DO not so much how they look
