A replica of the Hargrave Tandem Monoplane Glider of 1894 built by Rob De Groot, photographed at the Hang Gliding World Championships of 1994 – the 100th anniversary of the glider designed and built by the Australian pioneer Lawrence Hargrave. As the originals only flight was unsuccessful, Hargrave shied away in his career from monoplanes, adopting instead the idea of biplanes (box-kite designs). The tandem wing monoplane however, became a concept Langley later saw fit to continue with his Aerodrome in 1903.
