Assumption: If a not-in-the-right-of-way glider operation caused you to have to bank or move suddenly, and you lost it, wouldn't you ascribe just a smidge of responsibility to that operation?
I know you're a twin owner and much higher time pilot than me, but we know you can stall an airplane very easy at any speed, attitude, or angle. I don't fly twins, but it appears from utube and what I read they can be especially twitchy during stalls and power up banks I'm assuming. Very little margin for error. Are you saying you could recover from any emergency maneuver or even a stall in your twin at that low altitude, and the baron pilot just freaked out? Help me understand. Should he have just plowed into everything under control? As it turned out, they're all dead, so staying in control even if it meant hitting the tow plane or line could not have been worse for the Baron. It might have killed more people, so the baron pilot may have hero'd himself for all we know.
But stay under control is the moral of this story imo.
I'm working it from the Baron pilot's side here for no other reason than discussion ...
