My dad worked for IBM, and was contracted to McDonnell-Douglas, at the time. My dad called the assignment "Mac Auto", for whatever reason. My dad was there when the astronauts were told that they would be recycling their...drinking water. They were not agreeable to such immediate recycling, so changes were made. Those years were some of his favorite years. The contract ended, and my dad moved on to his next assignment.
As part of my dad's job, he had to work with the astronauts on various controls--including landing. As I type this, that doesn't make much sense. Anyway, if the spacecraft flipped or lost its orientation in the simulation, my dad had to adjust the computer controls; if the astronauts ran out of fuel, or crashed, it was their fault. Everyone had to keep working until the manager declared success.
I believe my dad was at Mac Auto before and after that project, but supposed to be on something else, and they appropriated him to help with that project.
