@Flying Stone, I agree with all of that.
I am a little uncomfortable when (other) people imply that the F/O has little or no responsibility for the safe operation of a flight. Of course they have. Sure if it comes to court, the F/O might not be the one in the dock, (although they probably will be), but if through their negligence or actions, an accident occured, that F/O is going to feel extremely responsible, whether legally so or not.
