I think that the acceptance of failure in certain domains is a problem of system design. Why shouldn't doctor, pilots, ship's captains, train conductors etc be held accountable (blamed) for mistakes? I don't agree with your statement that air travel is designed around the acceptance of failure meaning that pilots aren't culpable for their mistakes. Watch a NTSB hearing into a pilots failures, and there's plenty of blame assigned when appropriate. Doctors and other medical professionals should be similarly scrutinized and ostracized when they perform poorly.
