Gilbert, O

   In 1909 Octave Gilbert built a biplane glider based on the Wright design, with a single large rudder and large forward monoplane elevator. All surfaces consisted merely of fabric stretched over a frame outline. The pilot lay prone in netting slung between the wings, which had only 4 flat crosspieces for ribs in each panel - no camber at all. The undercarriage was made from 2 bicycle wheels and forks.
