Andy Griffith and his motley crew build a spaceship out of a cement mixer. Uh yeah, right. It was a decent kids show but the whole idea of surving a trip to the Moon inside a rocket with a space capsule made from an old cement mixer was ultra ridiculous. Then to top it off they had some kind of miracle fuel that allowed them to get there on 1 tank fuel while NASA required a multistage enormous Saturn V rocket. Then the government apparently had no problem with them flying this thing around the world for 16 episodes? And if it was so easy to get to the Moon, NASA -not to mention every other country- would have copied it and a new space age would have dawned.
Ok, it was ridiculous but I was a kid back then.
