Percy Pilcher, working as assistant lecturer at Glasgow University, builds and flies his first hang glider "The Bat". Following correspondence with Otto Lilienthal, he develops advanced glider designs that would influence early aviation development.

Pilcher's most successful glider design, "The Hawk", makes its first flight. This aircraft would later set distance records and demonstrate the viability of controlled flight in Scotland.

Flying his glider "Hawk" at Stanford Hall, Leicestershire, Pilcher achieves a world distance record of 250 meters (820 feet). His sister Ella assists with aircraft construction and flight operations, making her one of the first women involved in aviation development.
