A Tale of Two Captains.
One was the Captain of US Airways flight 1549 from NYC to Charlotte N.C - Chesley B. Sullenberger. The successful ditching of the Airbus A320-214, with no loss of any of the 155 lives, has been named the "Miracle On The Hudson". I do not wish to detract from the miraculousness of the event, but on October 16 1956, a Boeing 377 was successfully ditched in the Pacific with no loss of life. So a good case can be made that the "Miracle On The Hudson" was the result of training, experience and discipline of the crew of flight 1549. Pan-Am Flight 6 was their sole successful example.
The other was Captain of the cruise ship 'Costa Concordia' - Francesco Schettino. From what I have read, it is a tragedy that never should have been caused. In my opinion it stemmed from lack of training, lack of experience and lack of discipline. I do not not know how many similar maritime incidents had successful outcomes as to be called 'Miracles' (Wikipedia is down) but the 'Costa Concordia' disaster has eerie resemblances to the Titanic disaster. (I saw two movies about it). Then there is the movie "The Poseidon Adventure" which showed, very effectively, the unsurmountable difficulties in evacuating a ship that is no longer on even keel.
There is an adage, "Learn from the mistakes of others. You will not be able to make them all yourself; and it will cost you nothing." (Wikipedia is down).
I believe that the world will miss "Sully" and his generation's ilk. They attended the classes, studied the text books, completed the assignments, learned the tasks and mastered the job. They then put into practice what they had learned - each and every time.
