June 1915: On his arrival at ‘C’ Flight, Triggers' forthright manner and unusual ideas quickly make an impression. Seeing the inadequacies of the planes, Triggers encourages the pilots and NCOs to put forward ideas for improvement. Alan Farmer and his Observer, Bravington, get into trouble for firing a pistol to warn another British plane of the approach of a German plane, but this leads to a new strategy. Corporal Morgan, eager to win a weekend in Paris promised by Triggers, comes up with several ingenious plans for improving the plane's performance, but it is Alan who has a startling new idea that may help turn the tide. Back in Sussex, the Army begins recruiting in the village. Richard Hollis's grandfather, Sir John, leads the effort, and Lorna assists by playing the piano. As men come forward to volunteer, Harry receives news from Molly that Richard has been killed in an accident, during his first solo training flight. (thetvdb.com)
