Oh, come on....enough of that "twin engine/twin pilot save lifes" crap...
no, the point is that a twin-engine, twin pilot operation would generally have more checks and balances than a single-pilot operation.
You would at least have to display some CRM to convince the other guy that your plan was safe and thought through and you would have considered your actions in the event of a single engine failure and possibly modified your departure to take that into account.
You would probably have a better instrument and navigation aids suite with maybe a backup GPS or moving map.
Instead we have a one-man band, albeit with a passenger, who decides that a night unaided mountain departure is a good idea, has some sort of problem he wasn't expecting (whether it was environmental or mechanical I don't know) who didn't treat the situation with the respect that it demanded.
So it appears it was another loss of life based on a pilot misjudging the situation, and being overconfidant on skills there were not up to the game.
exactly.
