Sir George Cayley watched seagulls flying and realised that birds do not always flap their wings. The idea of gliding was born! Sir George was a native of Scarborough and around 1799, after making careful observations of bird flight he separated the forces involved in flight.

Sir george made many model gliders and even managed to get one of his servants to fly in a hang glider

One of Sir George Cayley's models
Otto Lillenthal was so rich he paid for his own hill to be made so he could strap a glider on his back and fly down this hill. He died in 1859. Otto's work advanced The work of Sir George Cayley and allowed others to develop gliders, kites and eventually powered fling machines.
