I agree to a certain extent with what you said Zanthrus, but I think we shouldn’t hold such a simplistic view of aviation safety unless that view allows room for consideration of the circumstances and factors that were present leading up to events such as these. If we don’t , we miss the opportunity to make improvements to the systems that support the P in C . We fail to get safer.
So, we can have “responsibility and duty of care” as well as finding shortcomings with other individuals and/or organisations.
My two cents anyway.
