Who is the owner of UFO?

Could you clarify who you are referring to when you ask, "Who is the owner of UFO?" Are you referring to unidentified flying objects (UFOs) as seen in the sky, which by definition are unidentified and therefore have no known owner? Or are you perhaps asking about a specific company, brand, or asset named UFO that may have a clear owner? If the latter, please provide more context or details about the UFO you're inquiring about so that I can give a more accurate answer.
