Papua New Guinea brought a few current CASA staff undone in their previous RAAF career.
Another CASA employee was responsible for DHC-4 Caribou A4-264 over running the end of the strip a Tufi on July 20, 1971.
I think there were around six Caribou prangs in PNG, including A4-233 which pranged in the Kudjero Gap on August 28, 1972, with the loss of crew and all bar one of 25 PNG Army Cadets.
