Ancient Aliens - Season 10 Episode 2

When German aerospace engineer Wernher von Braun joined the U.S. military and space programs after World War II, he quickly became one of the foremost scientists credited with developing the ballistic missile, the first American satellite and the enormous Saturn V rocket that enabled man to reach the moon. Von Braun's bold predictions that we would explore Mars and build a space station have become reality. But how is it that von Braun--whose contemporaries included such scientific geniuses as Nikola Tesla, Robert Oppenheimer, and Albert Einstein--was so far ahead of everyone when it came to rocketry? Did he have secret information collected by the Nazi party during WWII--or access to advanced technology recovered from the alleged UFO crash in Roswell, New Mexico in 1947? Or is it possible that the greatest rocket scientist the world has ever known found his inspiration not on our world, but another?
