It is nice to see that there is such a lively debate around this point.
...ATPL holder with 19,000 hours flew his B737-800 into Truk lagoon last year. And he was watched doing it by an ATPL holding co-pilot who said or did nothing until it was too late. Despite 16 EGPWS warnings...
I'd hope we could all agree that such per performance on the job is unexpected (without saying that it has never happened) and also unacceptable.
There is a big difference between me (as most of us would) not saying that it
couldn't happen to us on one side, and on the other side saying "that it can happen to the best".
Let us be our best, and let's assure to put all measures in place that it doesn't.
