P2-FHC
AVDEV (I read Cloudlands Av), all Islanders, FHC ex Mexico and went back there, FHO ex NZ, withdrawn from use (no date), FHP ex NZ, crashed near Mount Hagen on 12.07.1983, FHQ ex NZ, went to P2-ALF with Airlink, FHR ex Philippines, went to P2-MFT with MAF. So, seems FHO and FHP would be the two involved. How far is Lake Kopiago from Hagen? If someone comes up with the date for the FHO incident at Kiunga, bingo.
