Jemy,
There have indeed been many variations on the good old yard of ale. I well remember a course of pilots from a Middle Eastern country doing their command training on the 212 who tried a yard of Guinness - very messy
Pastis and tonic was my preference. It's a shame the Training School was closed down as so many good young men and women who passed through it have since done very well both in Bristow and other companies.
