Group Captain Al Sutherland
I presume that you may be alluding to the above Gentleman.
When Al departed No 55 Sqn in the late 1960s I replace him as Nav Plotter in Jock Carrol's crew. Bob Bonas was a superlative sidekick as Nav Radar and tought me so much about the Tanker game. I still have Al's notes on the intricacies of those magnificent Tanker Nav Tricks such as 'RV Bravos' etc
I had the pleasure in the mid 1990s of treating Gp Capt and Sally to a top nosh meal on Sydney Harbourside.
Lovely Man and Wife.
