The crash of a RAAF Caribou in Papua New Guinea on on 28 August 1972 involved an aircraft that was flying PNG school cadets from their annual training camp at Lae back to Port Moresby. It failed to arrive at Port Moresby and an extensive search was started.
Despite the search, it was not until three days later that four survivors were located near the crash site by an army helicopter, having attempted to walk out for assistance. They were able to direct rescuers to the crash site where a fifth schoolboy was winched out by RAAF helicopter, only to die later.
The Caribou’s crew of three, plus a ground liaison officer from the Army, and 21 school cadets were killed in the disaster.
I am gathering archival and other information on the crash.
