As the war progressed, Great Britain found that it needed more trained aircrew and more training facilities. Training was provided both by the Curtiss Aviation School at Long Branch near Toronto (land plane training) and Hanlan's Point on Toronto Island (for flying boat training), and in the United States. During the last two years of the war 3135 pilots and 137 observers trained in Canada and Texas for both the RFC and the new Royal Air Force (RAF). Of these trainees, 2,624 went to Europe for operational duty.
