I'm not convinced it's a 2-engine aircraft - if you listen to the converstation carefully there's only references to "the engine" except for when they're punching out at the end where he radios that they've lost "an" engine. No references to adjusting power on the other engine to compensate. I'm guessing it's a training aircraft given the part where the back-seater tells the other guy that he'll fly the plane and to work on restarting the engine up front. In any event, shows how one unlucky bird can ruin your whole day.
