performance (but better  gun platform) Hurricanes engaged the bombers. Shooting down German  bombers was the critical key since the bombers were attacking RAF  airfields in the first phase of the battle and cities after the  Luftwaffe changed target priorities. The film accurately depicts the  British need (and desire) to destroy bombers to protect their air  defense infrastructure and later protect civilian targets. For  similar reasons (the lack of working aircraft of the right type)  Spitfires and Hurricanes are shown flying together in tactical  formations whereas in reality RAF squadrons flew one or the other  type of fighter exclusively. Due to different performance  characteristics, the two aircraft would not fly and fight together.
