Vessbot, #136, "why not both" - system and pilot.
A glib response would be because you can never be sure that you have fixed the pilot, every single one, and for all of the situations that you can imagine.
Thus concentrate on the system, its never perfect because that also involves the human, but you should be able to improve previous efforts - learn and amend. And do not forget to place your trust in pilots because sometime they may be able to deal with those situations which management are unable to imagine.
‘You fix what you find; you find what you look for”. This crux of the point is that if you first focus on the pilot then the safety efforts may not progress any further.
Start with the system, this will involve humans; focus on how the system might help the pilots function - to do the day job, and not the other way round.
‘Fixing’ pilots in this incident (there were ‘fired’?) will not help the next crew faced with this or a similar dilemma.
