I recall 3 of these DCA examiners - Peter Griffin, Ron East and Tony Christie.
Ron would never tolerate fools, but I always got on well with him. In another life, I used to ride around occasionally in the Aero Commander (VH-CAY) that was based at Perth then and he would generally let me fly the aircraft. That left a lasting impression.
Leading by example comes to mind when I think of him. A lasting memory.
