The first time I heard "Jointery" put forward as the way to go was in 1960, when I was a Grammar School Army Cadet. In 1963 I joined the RAF and in all my service as a Maritime Pilot, I found that the Army were very keen on Jointery, but the RN considered themselves to be the Senior Service and the rest of Her Majesty's Services to be somewhat below them.
What were they smokin' at Dartmouth?
