Read this excerpt from The Man Who Went to the Far Side of the Moon.

Before Neil and Buzz can take off from the moon and return to the capsule, Michael has to make 850 computer commands. Surrounding him on the walls of the capsule are more than 700 switches, levers, alarm buttons, gauges, warning lights, and computer keys. There are sensors that should never, ever, point to red. There are yellow-and-black-striped buttons with functions so important that they are covered with plastic lids to prevent a tired, lonely astronaut from pushing them by mistake.
