It should be a Freemason flag the astronaut is saluting but don't let that distract you from listening to Peter Levenda, yet another researcher who carefully lays out the Nazi exodus to NASA (and more) after the second world war. He makes the point that the Catholics worshipped in secret for 200 years after suppression because that's what real cults to. They believe. Peter also makes the connection between Kennedy's olive branch of collaborative space travel to Kruschev before being gunned down in his successors home state on a visit arranged by LBJ. I believe they call that a coup d'etat.
The in-joke among followers of this subject is that NASA stands for 'never a straight answer'.
