“Unidentified flying object(s),” any aerial phenomenon that cannot immediately be identified or explained, often understood to be a craft of alleged extraterrestrial origin.

From the Ra Contact: There are four sources of UFO phenomena: weaponry of our governments, thought-form projections of the Confederation, crafts of the Orion group and, in isolated instances, those of no affiliation who penetrate the quarantine by chance; the reason for the increase in UFO activity in the thirty to forty years prior to the Ra contact was that our governments perverted technical information offered by the Confederation, and the Confederation felt a strong need to balance these distortions of information meant to aid the Earth.
