The Fight for the Sky is a short propaganda film commissioned by the US government to highlight the victories of the Allied air forces over Europe prior to the Normandy invasion.
Opening with shots of aerial combat over Europe the film turns to footage of the airmen acting casually in their base in East Anglia, reading newspapers, playing ping pong, and listening to the radio.
Captured German footage is shown to prove that the enemy was just as determined to stop the attacks as the Allies were to carry them out.
Then the focus turns to enemy transportation, and the Allies make it impossible for a railroad to operate at day, also targeting trucks, barges, and even flak towers.
A short version, narrated by Ronald Reagan, was released to theatres with a running time of approximately 20 minutes.
