Goes to show that any crisis, even a self inflicted one, can become a net win if you recover well, learn your lesson, and nobody gets killed.
With the Gimli Glider, Captain Pearson took some of the blame because he flew the plane when the minimum equipment list said he shouldn't have, and he miscalculated the quantity of fuel on board.
It's quite possible Captain Pearson would have been hung out to dry if there had been fatalities. Instead, his admirable performance in the air was enough to almost entirely outweigh whatever mistakes he made on the ground.
Whoa. I wonder if it was intentional or not to leave out an almost no-win simulation from the training.
