==Accuracy of Events==
The film has a general accuracy on the wider events of 303 squadron, but many details lack accuracy. For instance, Jan was showing as stealing a German plane to arrive in England in 1940. In reality, he escaped France by boat, like many other Poles as they evacuated from the advancing Germans. Gabriel Horodyszcz, one of the characters, is fictional, who is shown as a pilot who is reluctant to shoot the enemy. He, instead, wants to pray for his enemies and is shown as devout Catholic where he sets up a shrine for the pilots. Also, 303 squadron is shown as coming up with the idea of putting cameras in the cockpits of aircraft, but that was not their innovation .
