I am Pax of 56 years experience. I am just reading the autoiography of Dr Alan Diehl, legendary of the NTSB and FAA for the Human Factors training programmes.
He is fascinating and one of his earliest success' as an ASI was to reveal the illegal rulings of the the owner of Downeast Airlines (Robert Stenger) and the culture he had, causing the deaths of crew and passengers. The crash that revealed publicly what was already known in private, was in May 1979. That was a tiny regional in the new days of deregulation.
Now, with a major world carrier, 40 years on, here we are again. Unfortunately, too many countries do not want to upset the ME. As we know from The Tombstone Imperative, not enough people have died - yet.
