At my initial SEP when I joined easyjet it was explained that " a ditching was very unlikely because we don't fly over sea much"
I mentioned that a friend of mine had ditched a large aircraft just off the scotish coast due to fire and my last employer almost put and a/c in the sea off jersey by putting both props to feather instead of cruise.
You don't have to be mid Atlantic or lose both engines to end up in the drink!
