I just marvel at the uninformed things written here. In all transport category airplanes, including the ATR, Vmc is below V2, which is the single engine, best rate of climb speed. All transport category airplanes will climb with an engine out, provided they are at or below the max takeoff weight for the ambient conditions. It is illegal in the US to take off above that weight, and I find it hard to believe that any carrier, worldwide would do so. There is obviously more to this story, and it is in extremely poor taste to second guess what happened here.
God bless the crew, passengers, and their families.
