Being a bit anal retentive here, Gnadenburg, but 'Deep Blue Sky" was about Czech pilots, not Poles.
I do agree that it was a damned fine film.
On the subject of the Polish pilots who flew for the Brits during WW2, I loved the (apparently true) yarn about one Major Unprounancoubleski who had a little more trouble than most with his landings during his RAF conversion onto Hurricanes. But eventually he made the grade and was passed out to move on to operational flying.
Some months later, one of his instructors ran into another Pole and asked how the Major was doing. He was told that the Major was doing well on his squadron and had shot down a number of German aircraft.
The instructor commented that the Major's landings had been a cause for concern, and the Ploe replied "Well, vhat did you expect? Major Unprounancoubleski voz navigator back in Poland."
