Leroy et Marzollier

  Either at a meet titled Nantes Aviation, or under the firm name of Nantes Aviation, these 2 men from Nantes showed their glider on 14-21 August 1910 - perhaps they flew it. It might have been meant to have developed into a powered aeroplane, with its long uncovered trapezoidal-sectioned fuselage, trapezoidal wings with the spars on the upper surface, ailerons attached to the trailing edges, classic tail surfaces, and a forward elevator.
