I made my share of mistakes but they were caught by good CRM.
That's a ridiculous statement. Mistakes are made every flight and are caught by good CRM and other built in redundancies designed into the system. That's how it all works.
Landing at the wrong airport wasn't one of them. I was fortunate to get through the flying part of my career with no violations or incidents. Perhaps that was a lot of luck or perhaps a little bit of luck combined with adherence to SOPs.
The vast majority of airline pilots get through their career without violations or incidents. None of us make it through without making serious errors that had the potential to have ended badly. Call it luck or call it a result of a carefully designed system of redundancy that keeps us safe. In most cases it's a combination of both.
If an airline pilots uses all the tools he is supposed to use he/she simply will not land at the wrong airport.
You are a fool if you believe you are infallible simply because you follow rules. Why are the rules constantly changing and evolving? It's because the rules themselves are always flawed but it takes time and experience to iron out the wrinkles. Usually that experience is earned by yours or other's mistakes. You are arrogant because you think you are above that.
