The training facility depicted in the movie, "Uplands Air Base," actually exists near Ottawa, Canada. After WWII, it served as a jet squadron training base and later as a military helicopter transport facility. In 1995, the Canadian government shut down the base and it now serves as a reception area for VIPs.
This was the first Hollywood picture to be filmed entirely on location in Canada.
The graduation scene was an actual graduation ceremony of the R.C.A.F. with Air Marshal W.A. Bishop in attendance. He also attended the New York opening along with 200 R.C.A.F. cadets and other officials.
The film opened simultaneously in New York, London, Ottawa, Cairo, Melbourne, Toronto, Winnipeg and Vancouver. The R.C.A.F. transported film copies to these cities.
