Da Sylva

  Gomez da Sylva was a Portuguese who in late 1909 built a curious pusher biplane whose most distinctive feature was the curved downturned center-sections of both wings, coming to horizontal knife-edges. The fuselage was an uncovered rectangular box, with a pair of elevators forward which moved up and down independently; controls were 2 sticks on each side - there were no rudder pedals. Outriggers supported a pair of rudders and a rear tailplane. The whole thing sat on 4 wheels, the pilot far forward.
