Hi Bill..
Joining the RFC in Canada in 1915-1916 was no easy chore. I suggest you go to the local library, and look for a rather massive book entitled
Canadian Airmen and the First World War by S. F. Wise. The second chapter of this book,
Recruiting and Training in Canada, 1914-1916, has a very good analysis of the restrictive requirements for Canadians to join either the RFC or RNAS. At times, volunteers were required to obtain their FAI pilot's certificate at their own expense! This would be good background information for the "next generation" to ponder.
