Its Alaska there's a few loose cannons up here. Aborting at Dutch probably made a lot of sense considering once you leave do you really want to go back and do you even want to try and go someplace else on one engine.

I'd say 50% of Captains I've been flying with brief a V2 abort when departing out of Anchorage. Its not standard but it sure makes more sense safety wise than flying an airplane around on 3 engines and risk losing another. Hopefully my thinking won't get too tainted by flying up here.
