20-30K hours and all the bloody swiss cheese in the world doesn't make this better, it was a major screw up. Fix it.
Fix it. That's the aim that of most on this thread I imagine.
Firing the crew could be warranted I guess but what does it achieve? Almost nothing from a safety perspective. All the other crews remaining still have the same motivation not to crash as they did last week/ last month/ last decade.
Learning what factors lead to the mis-perception would greatly improve safety globally when the lessons were trained to tens of thousands of pilots through recurrent training programs.
It's easy to see reading this thread those who understand how Aviation achieved it's outstanding safety record and those who find comfort in the romantic notion that everyone up the pointy end is made of ' the right stuff'.
