[3]In 1944, the Allied nations, including Canada, created air supply routes to transport both troops and war materiel from home bases and factories to the battlefield.

A concern that national interests could create rivalries and hinder future development, led the United States to advocate for an organization that would regulate airlines flying anywhere in the world.

Equally interested in postwar air routes was Great Britain, whose aviation industries may have to retool to convert to a peacetime role.

[8] As part of The World in Action series, Global Air Routes was produced in 35 mm for the theatrical market.

Each film was shown over a six-month period as part of the shorts or newsreel segments in approximately 800 theatres across Canada.
