I'm not sure accidents have nothing to do with the subject..
They show that a problem exists.
Have you ever seen a general aviation accident where the aircraft stalled from a high cruise altitude and never recovered ?
This does not mean, obviously, that general aviation is exempt from piloting errors, but they have much less training (PPL vs CPL or ATPL + TR), much less practise (average of 12 hours vs 600 hours per year), and only pilot required.
So flying errors are much more suprising for commercial aviation. It looks like we don't make the most of our advantages (two pilots, and potentially far higher practise)
