CAT1 and MPH,
I have not been critical of the captain in this incident. He made a BIG mistake, as can any human being given the right (wrong?!?) set of circumstances.
What I do lay firmly at the feet of FR managment is the actions taken in the relative calm of the turn-around. The FO, clearly presented with an aircraft that required a maintenence inspection for the overspeed, a captain who admitted he was unfit to fly, and no doubt just a little shaken up himself- GOT BACK ON AND FLEW HOME.
Why? Refer previous posts. An FR FO, faced with a similar situation decided it was unsafe to fly, AND WAS SACKED ON THE ORDERS OF THE HIGHEST LEVEL OF FR MANAGMENT.
That is not error, that is not a mistake, that is a deliberate policy of intimidation, leading to a culture of "shut up and fly".
