I know humans make mistakes, etc., but...
If I were spending literal millions on a custom-made vehicle, I would expect it to do be checked with a micron-level toothed comb and do everything correctly up to laying golden eggs.
Or is that just me?
Remember the Mercury days, when even at the end Cooper's vessel couldn't even last ONE DAY in space before almost all the automatic systems had failed. Disregarding the level of such early 1960s technology, I just have to wonder why his ship couldn't have held it together for just 22 orbits? And there wasn't even any software onboard to blame!
