Chris, that is from
Fate Is The Hunter Chapter V, subtitled 'where the mind is honed and sweat is found to mix with ice.' The Captain on that flight was a guy named Hughen who had this to say about the circumstance, "If this were anything but a DC-2 we just wouldn't be in the air."
Like you, I've had a couple of experiences with clear ice in the DC-3. It's not a pleasant thing, one I would forgo any day. The PBY I flew had no boots, only prop alcohol, and during the season I spent on it we studiously avoided icing conditions. The worst icing I have ever encountered was with a Fairchild F-27, picked up on approach. After a hour in the warm hangar, chunks were still falling off the aircraft.
