I guess my point was that airline safety hits a sort of horizontal asymptote as you put in effort. You'll go years and years without accidents, have one, and then struggle to generalize a rule from this incredibly freak event. My biggest complaint is that the whole 'East Asian culture causes deference to authority, crashes planes' argument is a huge generalization with very little data to back it up. In any other context, the number of events we're talking about would be anecdotal.
