I did my civil IR (I had already held an RAF Master Green IR for many, many years) at Kidlington in 1974 with Dai Heather-Hayes.
He had a wonderful poster on the wall behind his desk. It showed two pilots sitting in a cockpit taken from behind with the instrument panel in front of them.
The caption was;
"Instrument flying is an unnatural act - probably punishable by God".
I thought that was a wonderful statement. Does anyone know where I could get a copy of this poster?
