It is a very odd set of circumstances, Centaurus. Didn’t the ‘bad guys’ fly the Stuka in WWII? That would account for ‘George’ being chased by the Soviets who were at that time among the ‘good guys’. But then how does he end up in the RAAF Reserve? Something does not add up.
I note, apropos nothing in particular, that ASIO was originally set up in response to the UK and USA suspending intelligence sharing with Australia, after they found out there was a Soviet spy ring operating in Australia, of which ring Australia was not aware. Aircraft transitting Darwin bound for Woomera and beyond? Seems the kind of information that might have been of some passing interest not only to plane-spotters but to the Soviets in the 50s and beyond.
Be fascinating to find out how ‘George’ got into the Reserve if he was, in fact, a Stuka pilot.
