G'day Kabwum,
Yep, repatriating formerly live people to their wantoks was an every day event.
I recall one charter to Sialum via Siwea. No dead person on this particular day, I had just one pax, the Siwea longlong man who'd been down to the Angau Hospital for a tune-up, and several boxes of stubble coolers for the inimitable owner of the Sialum Resort.
The first thing I noticed was the (relatively) exuberant performance of the 206 having just stubby coolers on board instead of 500kg of tinpis. After dropping longlong man off at Siwea, it was always a peaceful flight down the hill to Sialum.
Joining the circuit I noted a large crowd of folk in the parking area. Upon engine shutdown the (conspicuously abject) wailing began. As I started unloading the boxes of stubby coolers a local came over checked out the back of the 206 and declared that "no body" was on board and the wailing immediately stopped. A colleague then landed shortly afterwards, (he had the body) and the wailing was restored.
