One of the best ways to determine a secret space programme is when the deep state peddles a known informant as being a voice to trust. Bill Ryan takes an age to say what can be summed up in 10 minutes but its fairly evident that Corey Goode's testimony gets destroyed in this discussion.
I've no idea to what extent any secret space programmes exists or any breakaway civilisation associated with those groups but the chatter about TR-3B's has been consistent for years.
