You can go through any catastrophe in a complex system and piece together a chain of events that show how "obvious" it was that it was going to happen. What you miss are all the chains that say every complex system is going to end in catastrophe, because when they don't end, nobody looks. It is kind of an anti-survivor bias.
It is also why it is a bad idea to make policy changes strictly off the cause of a single failure, and that is where things like commissions should help: you can move the focus to looking at the entire problem set for weaknesses instead of just leaving it with "make a better o-ring".
