It's a true soldier's / airman's tale, very gritty, realistic, and a sheer experience. It's certainly not a barrel of laughs, but was totally engaging. Incredibly filmed, the music by Hans Zimmer is overwhelmingly brilliant with a touch of Elgar to be heard.
I'm not mentioning the lack of historical background (or whom they were actually fighting).
But it's more the story of survival of a group of men. Certainly food for thought.
Definitely a ride of a film. Proud to be British too...
And how the aerial shooting happened -
