If you have spare time on your hands I recommend you look at a thread that many of us think is the best on PPRuNe - look at Military Aviation ( its nearer the top of page ) and click on 'Gaining a Pilot's Wings in WW2'. Our senior member, Danny, has written extensively about his training as a pilot in the USA, and I think other posters have covered training in Canada. It may help give an understanding of your grandfather's time training to be a pilot.
