Many moons ago (more than I care to think of) did some comparison work on the curricula (curriculiums?) of the different air forces (lower case, includes navys) around the world. While this was curriculium only and didn't begin to get into the numerous other things that make a training program when you
compare French, British, Australian, Italian, Russian, German, USAF and USN curriclaa for tactical jets from ab initio to OCU/FRS/TRU whatever you call it the curricula were all remarkably the same in terms of total flying hours and proportion of hours spent in different subject matter areas.
The other thing that was good for a laugh was the USAF argument that the T-38 and whatever replacement there would ever be must be supersonic because of the curriculum requirement. When you looked at the flight sylabus they had 1 supersonic introduction hop (instructor drives, student watches) and 1 hop where the student drives and instructor watches) Of course this 3 hours in the whole program drives a heavier, thirstier, more maintenance intensive jet and costs mucho dinero over the life cycle. We decided to use a button to make the ASI go supersonic on instructor option and save the money to buy more aircraft and use them more.
