In 1910 Paul Bataille, a mining engineer, and Pierre Brabant, an electrical engineer who worked for Bataille’s company, filed a patent for a quadruplane. The lowest wing was originally going to be a “flapper” (aile battante), but when the quadruplane was actually built it had four fixed wing. The heavily reverse-staggered-wing pusher featured a high forward elevator and a four-wheel undercarriage. The machine was tested in Kiewit in 1910 and in 1911 at the Casteau exercise field where it was piloted by Aimé Behaeghe. After a week of testing, and a roll-over accident, with no success, the decision was made to modify the machine into a triplane. Eventually the aircraft was abandoned.
