Graham was the quintessential stick and rudder man. If it had wings...he'd probably have a crack at flying it.
I had the privilege of flying with GW quite a bit, including an instructor rating under his tutelage. I learnt an incredible amount in that month or so and it held me in good stead to enter the industry as a professional pilot.
A lovely bloke, a great pilot and he will be sorely missed. Rest in Peace.
