I too consider it a privalidge and pleasure to have met and learnt a lot from Gary when also working out of Goroka.
In my opinion Gary knew more about the AS350 than any other pilot I have met prior or since.
He was very clear in his explanations and demonstrations and most importantly inspired and encouraged confidence and professionlism both in the cockpit and outside for some of us who needed a little gentle guidance
Very very sad to hear this tragic news
