Going back a bit.....
So, in the past 20 or so years, how many times has the duration of Sandhurst and Dartmouth been changed?
No-one has answered that, so i can say that my Sandhurst course was 2 years, but had a very large "academic" content because the idea was that Sandhurst was the equivalent of a University degree. So we were turned out, up to the early 60s at least, as impeccably dressed, well-mannered 2nd Lieutenants without a huge amount of military skill, but well-versed in military history and, in my case, an Interpreter Class II qualification.
This is not all that relevant to flying aeroplanes; the Army's approach at that time was that driving its many aircraft, helicopters, Beavers, and so on, was a task that any NCO could do just as well as an Officer, so reasonably intelligent trainees from the ranks were promoted to Corporal (or Bombardier) when they went off to fly.
This annoyed the hell out of the RAF, who were determined to remove all non-commissioned pilots on the grounds that flying was an amazing skill that only Officers could perform, which was probably the main reason for the Army adopting that policy.
My Dad, wartime instructor (Rhodesia) then a Lancaster pilot shot down near to Munich and captured as a Sqn Ldr in 1943, said that lack of social skills training seemed not to make all that much difference to pilots' and crews' determination and ability to deliver their bomb-load accurately on to the target.
Some did it as best they could, some didn't. Some, very few, succumbed to terror, dumped the load under a shallow pretext and went home. Neither their commission or lack of it nor how they held their knife and fork was a factor, nor was their familiarity with a bow tie.
