Chimbu ... so maybe he did the Daugo thing twice?
Perhaps around the early 1980's Blackjack ran short of bang water in eight eigths over POM and peeled off to Daugo. The aircraft was an H4 registered Solair Baron, Cairns - Port Moresby - Kieta - Honiara after overhaul at Archerfield.
As it was a Solair aircraft, he didn't have the GV HF frequency (6.980 Mhz) so called the tower and requested they call GV/POM to send over a drum of fuel.
CAA got involved hoping to "get" Blackjack's PNG license for the final time, however it all got too hard with the aircraft being H4 registered and not being flown on a PNG license.
