Ian BB,
There was bound to be a huge overrun when the Japanese war ended so suddenly: we were all "caught on the hop", and it was months before some sort of equilibrium could be restored. Meanwhile most units carried on more or less by a process of inertia, and of course the flying training schools were no exception.
I can well imagine the disappointment of the trainees part way through their courses in the BFTS and in Canada (the Arnold Scheme in the US had ended in '43), but if the Bomb had not dropped when it did, they would have come out to join us in the Far East (for there would have been no sense in our being repatriated, even though we'd ended our "tours") and taken part in the land, sea and air battles which would precede the final combined services invasion of Japan.
As to that project, at the time it was generally accepted out there that the Allied casualty list would be about a million dead (the majority American). See:

"...Okinawa, an archipelago whose northernmost islands are about 350 miles south of the Japanese mainland .." (Barry Friedman, quoted by Google)
That shows the scope of the enterprise. The 201 Cadets of Courses 25 and 26 were better out of it ! and should count themselves lucky (as did I).
