Looked in to see why this was still running as I thought the early answers were definitive (don't ! ) and noticed the sad news of the demise of the club in Moresby, a handy place to score any over-supply of kai from the airlines so drinking could continue without break for food collection. I still wear my badge from the days when it was the Aero Club of Papua,surprising that no one has recognised it in a long time.
As for guns, I carried a pistol for years (legally) but there is a big difference between carrying and actually using in anger, consequences of which might be nasty..
There were enough problems with tourists and PNG condiytions without the present safety situation.
The good old days are gone.
