I knew about the von Braun team when I was still a child in the1960s. It was only them. They were mostly employed at the now Marshall Spaceflight Center (formerly part of Redstone Arsenal, home to the Army missile program). I've been there multiple times on work assignments. Have you ever been there? NASA had centers all over the country, working on propulsion, aerodynamics, airplane flight control, and a host ot aviation subjects. The von Braun people were only part of a much larger whole.

The team was all fired from NASA after von Braun was kicked upstairs to Washington DC, to be basically in charge of nothing. (He resigned and died of cancer a few years later.) Looks like simple envy and resentment that they had such a prominent and indispensable role in engineering the Saturn V launch vehicle that took us to the Moon. They have been gone for half a century.

So much for the idiotic assertion that NASA was all Germans. Not to mention the ridiculous libel that they were all Nazis at that time. Every German under Hitler had to be a member of the Nazi party, or they wouldn't be permitted to work. Von Braun and his team had been employed by the German Army for their work before Hitler came to power. They threw all that overboard when they decided en masse to leave Peenemunde and surrender to the American forces. (Still reading your history?) I'm part German. I've been witnessing the casual, acceptable anti-German bigotry in this country all my long life. I guess for you, World War II is not over and you are expecting to turn up the Red Skull if you look hard enough.
