I watched this movie at a friend's house out of state and we had an interruption that prevented me from seeing about the last 10 minutes of the movie, so I don't know how it ended, could someone please fill me in....I quit watching it as he was walking away from his dog at his former girl fiend's house.
That's pretty much the end. There was one more scene of Franta and the other political prisoners in the work camp. Their guard fell asleep and the sun shone in through the windows. They stopped working and enjoyed a brief moment of "freedom". There was also a coda that described how long the pilots were imprisoned, and when they were finally declared rehabilitated. IIRC, they were released in the 50s and finally pardoned (ha!) in the 1990s.
Marlonius missed an important point, the very last bit of the film. When the guard falls asleep, allowing them to enjoy a moment of freedom - Frantisek starts daydreaming about flying again and Karel's plane approaches him and talks to him over the radio, saying that he had had his back all along. The last line adds a moment of levity - as during the war, the British break in on their conversation, telling them to speak English please, and Frantisek answers, "Sorry, but this time it's personal."
