1984, you sound as if you're trying to shift the blame from the pilots to the training you received.
I had under 200 hours when I started flying commercially and in the subsequent 15 years or so I have never, ever, ever "busted" any minima.
Can I ask you if, during your training, you had ever practiced a diversion?
You say you never practiced the Cork scenario in training. Really!? You never practiced 3 approaches below minima, illegaly and dangerously?
He would have known right from wrong, but lack of experience and sheer nerves/adrenaline will override good CRM and adherence to SOP's.
I take particular exception to this. Good CRM and adherence to SOPs will override lack of experience and nerves, that's called being professional.
Do you think that a simple diversion would have been so nerve wracking?
