Canada found itself at war with Germany on August 4, 1914. Several European nations were employing the airplane as a military weapon. Canada, however, had neither aircraft or aircrew in her armed forces.
The Canadian Forces 431 Air Demonstration Squadron, is the product of a proud history of military aerobatic demonstration teams.
The air battle over Britain was fought in three overlapping phases. From July 10 to mid-August the Luftwaffe hammered at shipping in the Channel and at the docks and harbor facilities of southern England. From August 13 to September 6, it concentrated on fighter airfields and aircraft factories. The Germans might have won if they'd kept at this. Instead, in the third phase, they turned on London and other cities, hoping to break the will of the British people.
The British Commonwealth Air Training Plan Agreement, between Canada, the United Kingdom, Australia and New Zealand was signed in Ottawa on December 17, 1939.
