My thoughts are that as the airlines don't believe it will happen, the "company minded" aircrew also think the same.
Due to my background, I'm always considering a ditching if things go haywire.
I know I will incur the ridicule of some (like a previous poster), but I sometimes wonder if the pilots of say UPS6, SWR111 and say SAA Flight 295 even "considered" such an option.
I knew a pilot once who was so glad to have the sim exercises over early. "What did you do then?", to which the reply was, "go home."
I was astounded and I remember my reply "you are bloody mad, why didn't you do some dead-stick landings?". Needless to say, I was scoffed at.
For me, every minute in a simulator is an incredible learning experience which I valued.
