Apollo 13 oxygen regeneration emergency

Workaround engineering when the design-time quality system has already failed. Brief aside reinforcing the Hubble teaching point.

There's often a way to work around the problem. That's the story of Apollo 13, where they had to come back and make their CO2 scrubber. These guys were going to die. Tom Hanks was about to die, right? Apollo 13 was the movie. The NASA engineers had to use duct tape and other things to figure out what was available on the lunar module and how they could regenerate the oxygen out of the air. There's often another way to work around it. In this case they worked around that.
