[Teuthida]

Before UFO sightings were commonplace one have would list off all the things they could think of that flew trying to figure out what that thing in the sky was. If one were to see Superman in this day in age they would say "It's a UFO...wait a minute. Nope, it's Superman." Since before they realize that the flying thing in the sky is indeed Superman he is an unidentified flying object...or a weather balloon.
