I am deeply shocked to hear of Ian's passing, and, given that the weather was reported to be quite good, somewhat mystified that an aviator of Ian's skill and experience would come to grief like this.
I believe he was the BEST check & training pilot I ever flew with in a GA aircraft...............bar none. I will long remember my Baron endorsement with fairly spectacular Vmc demonstration.........the ex-GV Baron drivers reading this will know what I mean! Such was the thoroughness of that endorsement that I took Barons to some pretty "icky" places, but am still around today.
Ian loved flying in the bush, was not afraid of hard work, and was always willing to share his skills and knowledge with those of us who were still a little wet behind the ears.
He flies with the angels now.
RIP
