Borgnis et Desbordes de Savignon

   After Achille and Paul Borgnis had left Firmin Bousson, they found another partner in Desbordes de Savignon, and built another triplane which may be considered a development of the second Bousson-Borgnis. It was of all-metal construction, built at Gennevilliers, with wings like those on the big Vaniman - they might have been built by Vaniman. There were no rear tail surfaces: steering was done with ailerons set on forward outriggers, and a forward elevator was set low ahead of the 4-wheel undercarriage.

   (Span: 14.5 m; wing area: 80 sqm; gross weight: 570 kg; 28 hp 6-cylinder engine)
  
   Modified, with new undercarriage and elevator moved to the rear, it was driven to Yffiniac on the northern coast of Brittany, where it flew and made a "memorable crash." Repaired, at the end of 1910 it was destroyed in a collision.
