Gonnel

  This strange design by Arthur and Georges Gonnel was completed and tested by Pappaert at Juvisy in March 1911; it is unlikely to have flown. A square-sectioned uncovered fuselage sat on 2 wheels; the engine was set inside just over the wheels and drove a tractor propeller through a shaft. Above the fuselage, extending its whole length and about as wide, was a long covered boxlike frame, with fabric-covered extensions down each side, making rudimentary wings or fins. The underside of the box was left open, in which the air stream was to "induce a lifting reaction which ought to make it fly."
  The machine was to be operated from roads: it was named Uniplan.
