The story of a group of Scottish pensioners who spent 25 years building a replica First World War biplane. The original Sophie the Sopwith Strutter made history by becoming the first plane to land on Britain's prototype aircraft carrier - but for her modern pilot, flying a 110-year-old design is fraught with danger.

On an airstrip in Kent, engineer Nicky Wood and her team rebuild an RAF Tiger Moth biplane - one of 8000 that played an unsung role in winning The Great War. Outdated and barely able to reach 100 miles an hour, they gave tens of thousands of allied airmen the skills to fly and fight.
