Thank you Sharpie for a most comprehensive, and sobering, list.
A couple of edits........
1978 Nov Father V. Cafarella Cessna 206 -PAX Nr Gembogl Cru
Although he was flying for the Catholic Mission, Vince was not a priest; just a bloke who loved PNG and loved flying. his wife perished with him.
1982 Sep G. Craig Cessna 206 -SEG Nth Doma Peaks Cru
In fact Gavin Craig survived, although one of his passengers perished during the night they spent on the Doma Peaks. the passenger was uninjured, and possibly died of old age.
Fly safe.
