For what it's worth ... Back in the mid-70s my mother was working as a stewardess for some fancy private East coast airline (the name of which escapes me at the moment), during which time she frequently served von Braun. They became friendly aquantainces. She remembers him as being one of the kindest men she's ever met. She was especially impressed by the lack of arrogance and pretention in the man.
That's her view of von Braun, anyway. I never met the man and know nothing else of his personality or character. Perhaps he was just a charming smoothee making the moves on a good looking stewardess.
Who isn't?
