In the real world, not only had they looked at it, Mattingly said they had simulated something similar. An Apollo 8 simulation tackled the problem of what to do if one of the cabin fans had jammed up due to a screw that floated loose.

"The solution that they came up with was that they could make a way to use the vacuum cleaner in the command module with some plastic bags cut up and taped to the lithium hydroxide cartridges and blow through it with a vacuum cleaner," Mattingly said. "Well, on 13, someone says, 'You remember what we did on that sim? Who did that?' So in nothing short, Joe Kerwin showed up, and we talked about 'How did you build that bag and what did you do?'"
