I think it is more attributable to situational awareness. Night flying over the ocean is difficult but not all that possible. Two radalt's on board and nobody watching the ROD or either RA.
Not that long ago we were deep in discussion regarding the NVFR accidents of the coast of Queenland. This goes to prove that 2 pilot, twin engine makes absolutely no difference. Give me more training and more practice and maybe a good autopilot.
Like Nick preaches, 2 engines are often irrelevant.
MORE TRAINING, MORE FAMILIARITY = Less accidents.
Good to see that the survival suits worked well and obviously the HUET training.
