As the film says at the end "the characters and events depicted in this motion picture are fictitious any similarity to actual persons, living or dead, is purely coincidental". Very brave to show this film, in the way done, as it truly shows the heroism these people showed against seemingly insurmountable odds. To continually jump in their planes and take to the skies against this presence, of might and power, is truly a showing of the British "Stiff upper lip". Bearing in mind over the previous year the "Germans" had seemingly vanquished the whole of Europe, I'm sure they felt Great Britain "that small island" would cave as well.
What was so lovely about this was the camera angles, and shots made, in the sky. The German Luftwaffe "big planes" simply being overpowered up there as they couldn't turn in time to face the British "little planes, Spitfires" that just flew between and around them. Skies above GB recaptured by end October 1940, the Germans abandoning their attempt to secure those skies. As PM WC says "Never in the field of human conflict was so much owed owed by so many to so few". Well said that man!
