On the topic of ditching or overweight landing, the latter was something we practiced regularly in the Nimrod Sim. Trouble was, following Art's successful ditching, everybody started opting to "put it in the water". We, the instructors, had quite a time persuading folk that Art's circumstances were ideal; the aircraft was light, the water was calm - and it still broke in half!
Art will know I'm not taking anything away from his outstanding job, but in anything other than ideal circumstances ditching is merely a form of crashing.
