Continuity mistake: In the scene near the end when the men are done dragging the plane, one of the men unhooks the dragging strap under the left wing. In the next shot, it shows the pilot standing on top of the wing with the strap still attached. When the men climb the ladder to board the plane, the strap is gone.
Factual error: Before the damaged plane is dismantled, in some shots the three propeller blades of the port side engine are a mixture of clockwise and anticlockwise type. (The twist along the length of the blade goes the opposite direction depending on the type).
Continuity mistake: When the Sergeant finds his Captain after the Captain's return, the blisters on his nose are prominent. Later they have disappeared and they come and go throughout several scenes.
