A British biplane flies on, though the pilot and observer are both dead. The aeroplane was observing artillery when set upon by enemy Albatros scouts. With the aid of another aircraft from the same squadron, the British 'plane was able to drive the enemy planes away back to their lines. Assuming all was well with the first British 'plane, the second returned to its aerodrome. When it failed to return, it was only found the following night, fifty miles from the scene of combat. Both pilot and observer had been killed during the dogfight, and their 'plane had flown itself in broad circles until running out of fuel.
