Complex is a good description of von Braun. Read the definitive
biograply, Michael Neufeld's Werhner von Braun: Dreamer of Space,
Engineer of War. I don't mean to excuse anything he did or was
involved in. I'm just saying Neufeld's exhaustively researched bio
goes into depth I could barely touch on in my 2004 book The First
Space Race.
The Nazi secret government - UFO thing... hmmm.. Don't you think it
might mean a little more if there was a fractions of a shred of
evidence besides attributed statements floating on the Web?
