Private Jet, I'd have to disagree with you that the 2 are linked in the way you describe. If the cause of the crash isn't positively determined then the crew can't be blamed. Thankfully, safety management has moved on since the accident and finding the guilty party has given way to understanding everything you can about an accident or incident and fixing all the problems you can and managing the risks of the ones that you can't. A structured application of Just Culture is a huge step forward. For a bit of light reading I can whole-heartedly recommend "Whack a Mole" by David Marx. The hard part of course is that "To Err is Human, to blame is even more human".
