Filming in England was at Duxford, Debden, North Weald and Hawkinge, all operational stations in 1940 – one surviving First World War "Belfast" hangar at Duxford was blown up and demolished for the "Eagle Day" sequence. Some filming also took place at Bovingdon, a former wartime bomber airfield. The title sequence scene, showing a review of German bombers on the ground by Fieldmarshal Milch, was filmed at Tablada Airfield in Spain. Stunt coordinator Wilson Connie Edwards retained a Mark IX Spitfire, six Buchons, and a P-51 Mustang in lieu of payment, which were stored in Texas until sold to collectors in 2014.
