Crab,
I agree with all that but your penultimate paragraph identifies a problem.....the individual Pilot and Crew Member along with everyone in the process....and Operator and Authority must also see that there are no pauses, detours, or stays to that journey towards improvement.
I would suggest we might be seeing some systemic failure on display here that caught some folks out one dark night that caused them to pay a terrible price for that.
Formula One cars fail to win races unless all the bits and pieces come together to provide the driver a Ride that will afford him a chance to win if his performance is up to the task.
