Not sure where you got that. UFO, or unidentified flying object, means unidentified flying object. Calling something extra-terrestrial simply because it's unidentified doesn't work. To me there is zero correlation.

You and I are not commercial airline pilots or Air Force officers. In the past if they make a report about a ‘UFO’ their careers are likely finished.
