I think there were some stories about this from Challenger. The cost, be it financial, political, or other was so great to get a part “space rated” that they’d use redundant bad parts to cope with errors in some cases. I vaguely remember this being used to describe a temperature sensor that was wrong like 1% of the time, they used a group of them and some algorithm to filter out error. Can you think of a more geek sexy project than working on a rocket, space craft or jet? Then the reality is that it has to be about the least satisfying engineering job around, it looks like you have to make a titanic effort just to do something
