I worked with Don and to me he was a great mentor. He loved the aviation industry and despite having a wonderful career, Don was very down to earth and loved GA. Having finished a distinguished period with BASI, including being in charge, he was very happy to be back flying, and spoke of the very challenging MU2. I can recall exactly where I was when I heard of the accident on ABC radio, and sadly I had a gut feeling Don was in it. He was a very special individual, the likes of whom you are lucky to know, let alone be close to. Not forgotten Don.
