May 1915: Alan arrives at ‘C’ Flight in St Marie, France and faces resentment from some officers because of to his background (‘A blacksmith? We are getting desperate for chaps’), but quickly wins over his CO, Captain Dornish, and is delighted to be reunited with his friend Charles. Following the death of another NCO on the day he arrives, Alan, initially sent out as a "spare" pilot, is sent on a mission to range for the artillery, in the company of Lt Richard Bravington, an experienced Observer officer. When they are attacked by a German plane, equipped with a machine gun, Bravington is wounded. Alan fails to follow Bravington's instructions correctly, and lands the plane behind enemy lines. However, he uses Bravington's rifle to fight off an attack by approaching German soldiers, thus winning Bravington's regard. At home, Alan's mother is invited to the cinema by the local grocer, Mr Rudkin, and Harry appears jealous, until she reveals that she has turned down a second invitation because she is not romantically interested in Mr Rudkin.
