Following right behind Vol. 1 Aviation in Canada: The Pioneer Decades, and Vol. 2 Aviation in Canada: The Formative Years, Vol.3 Aviation in Canada: Evolution of an Air Force is another “must have” book for any sincere fan of Canada’s great aviation heritage. This lovely assemblage of paper, ink and glue picks up where The Formative Years finishes: Between the wars and on the homefront 1939-1945. The story begins with a handful of capable, dedicated WWI veterans, determined to establish a peacetime air force. Equipped with war surplus aircraft, they negotiate for funding and set to work. In the late 1920's, the RCAF finally acquires its first modern fighting machines, but Ottawa has little interest in a fighting air force. World war comes in 1939 and the miniscule RCAF blossoms into a large effective air force. The BCATP spreads across Canada. Coastal defense squadrons form with Hudsons, Cansos, Digbys, etc. to meet any naval threat. In every role on the home front the RCAF excels. The photo coverage is magnificent - over 800 photos.
