I fly SE night without any worries. Usually I will end up over sea so it doesnt really bother me if I am going to crash in the light or dark, either way I am going to get wet or dead.
I have flown many more hours in day light than night time and I have had only one engine failure, so I am not quiet sure why everyone seems to have issues with night flying in an SE aircraft.
Maybe it is because darkness makes the engine more prone to failing????
