divert to an undamaged airfield. A crestfallen Septic returns to his ground duties. Eventually, a reinstated Septic joins in Pimpernel's operations but he is mortally wounded while shooting down a German aircraft. His last words are heard over the Sector control room tannoy (public-address system), when he tells Small that their planned return foot race will have to be "postponed indefinitely". Small replies "Your message received and understood. Out". The final shot is of Squadron Leader Clinton's wife Nadine (Dulcie Gray) hanging an oil lamp in the ruins of their bungalow to aid returning pilots.

IIc aircraft (N ° 544, 554, 600, 601, 624) came from the Portuguese Air Force. The aircraft were all painted in the colours of No. 56 Squadron RAF and were based at RAF Kenley during the filming. The Squadron letters of No. 56 Squadron were ‘US’. A number of Hurricanes seen in the film carried the squadron letters 'AV' which were the letters of No. 121, the second American Eagle squadron. Other RAF types seen in the background include North American Harvard training aircraft, Avro Anson and Supermarine Spitfire. The enemy aircraft were represented by a captured Messerschmitt Bf 110
