In honor of Astronaut Farmer's release, I thought I'd dig up a gem.
SALVAGE (1979) with Andy Griffith and Joel Higgins.
Nothing quite like throwing out a few minor constrictions like the gravitational constant to further the plot.
The pilot for the short-lived series that should have been called "What do we do with this Home-made spaceship now?", SALVAGE featured a gaggle of out-of-work NASA engineers working as junkmen for Harry Broderick, ex-Korean War pilot and salvage aficionado with a plan to bring back space-race artifacts from the moon. Also, perhaps the first television portrayal of computer hacking in network history.
