Isn't the whole point of UFO's that they are unidentified? Don't they stop being UFO's the minute we find out what they are?

A UFO could be a drone, or small aircraft. There have been a lot of UFO encounters by our armed forces, including those with novel capabilities, and capabilities we do not understand. It is beyond unlikely that any of these are alien to Earth.
