The movie's producer Dean Devlin gave Dirk Maggs permission to produce an original radio adaptation provided that he did not reveal certain details of the movie's plot, and that he did not depict the British as saving the day. Maggs wrote, produced and directed the programme, with Devlin credited as "Creative Consultant".
In order to achieve authentic aircraft sounds, Maggs' crew recorded actual aircraft and cockpit interior sounds at an RAF base.
The programme's tagline is, "It's the Battle of Britain all over again, but this time our enemies aren't just unstoppable. They're inhuman".
