In past decades whenever military pilot reported UFO they were laughed at, sent to psychologist, evaluated, sent behind the desk. Other pilots knew and when they saw something really weird they have kept it for themselves.
Then the higher ups panicked. If they don't report our drones, they will not report Chinese or Russian drones either. We have hundreds and thousands of eyes in the sky but they will not report because they are afraid to speak.
So they came up with a campaign. They started to publish official UFO footage and started more openly talk about it to show pilots that it is now ok to talk about UFO. Don't be afraid pilots, if you see something strange jus tell us, we take it seriously now.
There are no aliens. Videos you saw are created or modified to look legit, and officially supported or confirmed.
