My initial post was simply to urge a sense of respect for those no longer with us.
I learned on the Cessna 310 that dead leg meant dead engine.
Ever since I have corrected yaw with a foot on a rudder pedal. That gets the ship airborne (you hope) then you have time to investigate what might have gone wrong.
A scan of the engine instruments should give a clue.
Best now is to see if your colleague agrees, beware, he may agree to please.
Those of you on light piston twins will know far better than I that there may be an element of time involved to get a prop feathered which would otherwise create drag.
Even on jets which are not so critical I remember an MEA 707 crew training at Beirut when, presumably, the student hit the wrong rudder and screwed into the ground before the check pilot could take over.
Best advise is ... Correct the yaw, get it safely airborne under control and then say what went wrong.
OK! I know, it ain't always that simple.
