I had an uncle that was deputy director of design for the apollo project. Men like Grady Williams are very few & far between these days. He answered directly to Von Braun. He also managed the skylab project. I can promise that he was such a man of itegrity, that he would've walked away from nasa if anything was fake. He grew up under an old school baptist preacher. That ought to be enough said about him. Yes, men from America walked on the moon. He knew them all. One of the astronauts, I believe it was Jim Irwin, became a christian because of his apollo experiences.
