I hereby propose a change of paradigm.

If you've decided that a UFO is an alien spacecraft, it's no longer a UFO. This is because "UFO" means "unidentified flying object". If you've identified it as alien spacecraft, then you can't call it a UFO anymore. You either need to call it a IUFO or simply "alien spacecraft".

For chrissakes, you guys. I know you're having a dandy time without your medication over there, but at least have your semantics make sense.
