I agree, Angie. It's strange for me to think that was half a century ago and how much has changed. When I saw the movie Apollo 13 - and that was nearly a quarter of a century ago! - I was startled by seeing the guys in Mission Control with their slide rules! And how about the first cosmonauts in space? They returned to Earth by parachute, because that was safer than landing in their spacecraft. (That was a well kept secret for a long time.)
