I remember passing through Girua one day on the RPT run from Lae.
The local Talair pilot (and numerous helpers) were loading a tranqualised cow into the back of a C206. It was the funniest thing I’d ever seen, although I did feel a little sorry for the poor old cow, still showing some signs of consciousness!
I can only assume the cow arrived safety as there was no adverse chatter on the company HF network after that.
Unlike the infamous Pig incident!
