Not to mention emergency life support requiring active intervention to work. It was like having seat belts that required you to push a button to engage in the event of a crash. Not surprisingly not a single astronaut survived Columbia's depressurization at altitude, because of failure to engage active life support. (A blessing because they had a literal snowballs chance in hell of surviving what followed, but still...)
