Do the aliens fly in UFO?

Since UFOs are unidentified, it is unknown what flies in one of them.

UFO s are not unidentified do not use the Word UFO.Use the Word ophanim/n if you want a modern term to use say IFPs intelligent flying phenomenon.As far as aliens in UFOs well since these beings are not purely physical they seem to be PART OF the whole thing.Why they need/are of, or use vapourous rings who knowns.The clue here to you is.. have you ever wondered why a light source comes down from within this,it the light part of or separate from the disk,are the disks a guided phenomenon because vapour/gas can scientifically hold light,does it pass through or does the vapour start to glow because it is spinning?
