Royal Canadian Air Force bomber squadrons which served overseas during the Second World War were not only identified on the Commonwealth air forces order of battle by the customary squadron number but by a title or nickname as well. Additionally, Canadian squadrons received formal sponsorship and support, generally from Canadian communities or other organizations. In one instance the sponsor was a major Hollywood film studio which also mobilized its roster of movie stars to the cause. Needless to say, these practices were something of a departure from the general orthodoxy within the parent RAF, where the normal practice was to identify squadrons by a unit number only. Nor were they much observed within the other Dominion air forces. But for Canada they played a part in fostering the identity and esprit of the RCAF, publicizing the contributions of Canadian bomber crews and serving the policy of Canadianization.
