When I first saw this program on TV I knew instantly that I had to obtain a copy of it and I did. I feel that this is the best space documentary ever made, period. The fact that this documentary draws directly from the original mercury and gemini astronauts tells the story from those who lived in it. A lot of information about the space operations of NASA I had never heard about till I saw this and they were quite amusing. Sadly Deke Slayton died during the making of the film and Al Shepard just recently died. This film is a final tribute in my mind to two great Americans who helped lead all Americans into the unknown depths of space through their pioneering careers as astronauts.
