On the third anniversary of the Plan President Roosevelt enthused that the BCATP had transformed Canada into the "aerodrome of democracy", a play on his earlier description of the United States as "the Arsenal of Democracy." Wrought iron gates were chosen by the UK, New Zealand and Australia to commemorate Canada's contribution to the Plan, and were placed to overlook the parade square at CFB Trenton. Various aircraft, transport and training artefacts may be seen at the Commonwealth Air Training Plan Museum, located in Brandon, Manitoba. As Canada was the main participant, the legacy of the plan there included a strong postwar aviation sector and many new or improved airports across the country, the majority of which are still in use. The classic BCATP airport consisted of three runways, each typically 2,500 ft (760 m) in length, arranged in a triangle so that aircraft could always land (more-or-less) into the wind – that was critically important at a time when most light training aircraft (such as the North American Harvard) were taildraggers, which are difficult to land in strong cross-winds. That triangular runway outline is perfectly preserved at Claresholm Industrial Airport, but is still easily visible under later runway extensions at most Canadian BCATP airports, such as Kingston/Norman Rogers Airport, Boundary Bay Airport and Pendelton, Ontario airport. Later modifications have often resulted in one runway being lengthened to handle larger aircraft such as jets, and in less-used runways being closed or converted to taxiways. The BCATP provided an economic boost in the Western provinces that were still recovering from the decade long depression. The final report of the BCATP Supervisory Board calculated that "more than 3,750 members of the RAF, RAAF, RNZAF and Allied nationals under RAF quotas married Canadian girls," many of whom remained in Canada to raise families. In 1959, Queen Elizabeth II unveiled The Ottawa Memorial, a monument erected to "(commemorate) by name, some 800 men and women who lost their lives while serving or training with the Air Forces of the Commonwealth in Canada, the West Indies and the United States and who have no known grave." The Commonwealth Air Training Plan (CATP) Museum is a non-profit, charitable organisation in Brandon, Manitoba, founded and operated by volunteers. The museum is dedicated to the preservation of the history of the British Commonwealth Air Training Plan and serves as a unique memorial to those airmen who trained and served, and especially those who died, while serving their country in the air war of 1939–1945.
