Aviation safety is about catering for the weakest in the chain through prevention, not a cowboy can do attitude, so prevalent in the profession.
Strongly agree. A healthy culture of safety works from the bottom of the risk pyramid up. On the other hand, pilots, trainers, and staffers should be held to, and select from, the top of the pyramid. Institutional and regulatory standards should foster a high level of competence. In this case, we may find failures on both ends. That is yet to be seen.
The important thing is that in considering safety, the after action review should be ruthless and impartial. Just because one side erred does not mean the other should be absolved. In the case of air accidents, there are often numerous factors which arranged themselves just right to kill people. It's a dangerous mindset that calls on failures on one side to acquit the other.
