...what you younger aviators feel about single engine ops over the water imc at night etc.
Define "younger" first ;-)
Personally, I can not imagine that I will ever be desperate enough for flying time and/or money to do that myself. And flying privately even less so. But then, what do I know about the future?
And about day or night I really don't know if that makes any difference in these waters. You either wear a full immersion suit and carry a raft for the least chance of survival or you will drown a either way.
