A DC3 crashed in Canberra many years ago because the crew put the heat controls in full hot and both engines detonated themselves to death. Followed by the airplane and crew.
Have you got any details on that accident? I flew Daks for many years in that area and don't recall that specific accident. There certainly were two Dakota accidents that I knew of; of which one was at Canberra airfield around 1953-4 . That was a runway port propeller shortly after lift off and the aircraft crashed inverted killing all aboard. Another was an engine failure in cruise over the mountains north of East Sale and tracking for Canberra and despite full power on the live engine it was unable to maintain height and eventually crashed into a hill killing a few on board. Whether carb icing was involved or not I don't know.
