For which case(s), specifically, and how does human error resolve the issue? Or do you not know any specific credible cases of unexplained UFOs, and just dismiss the entire phenomenon because of its "low probability." (I'm being facetious because many or all of the interesting cases easily rule out human error as the source of the phenomenon. Simultaneous human (and radar!) hallucination maybe, but not error.)
