Just going back to Ian B-B's post 7521 on p377 for a moment; my father went through grading school at Shellingford in March-April 1944. He also had just one instructor, Sgt Porter, and went solo on 6 April in Tiger Moth T5842. Incidentally, when I did my PPL in 2003 I also had just one instructor. Thanks Alan.
Dad then followed a similar path to 5BFTS at Riddle Field near Clewiston in Florida, where he joined 25 Course in April 1945. Well through his training by August 1945, the dropping of the atomic bombs and subsequent surrender by the Japanese curtailed the course, and his last flight in AT6-D "AS", a one hour solo trip, took place on 6 September.
Some sources state that the training schemes in the US stopped immediately after VJ Day (15 August 1945), but my Dad's log book shows otherwise.
I hope this is of interest; I have followed this thread for some time and find it truly enthralling.
