Maybe it has happened with a whisper, not a major public announcement or event.
Maybe the tipping point was the recent publication of journalist Leslie Kean's book "UFOs: Generals, Pilots and Government Officials Go on the Record" or a recent press conference by retired Air Force officers.
Or, it could have been the steady release of information through discreet ways via Hollywood movies, TV shows and other communications platforms over the past months, years and decades.
