Tha Antoinette III was a pioneer aircraft developed in France during 1908.{{Citation needed|date=December 2012}} DevelopmentAfter the limited success of the Gastambide-Mengin monoplane Levavasseur completely revised the design resulting in the Antoinette III. The inadequate roll control was not greatly improved, retaining the wing warping of the Gastambide-Mengin. Ground handling and take-off / landing performance was improved, however, by revising the complex inadequate quadricycle undercarriage of the Gastambide-Mengin, with strut supported wheels forward and aft on the centre-line and side-by-side wheels midway between the singles. Other improvements came in the form of the cruciform tail unit with large triangular fins above and below the rear fuselage, as well as the large tailplane, all of which supported triangular control surfaces.[1] Control was found to be marginal at best, but short flights were made regularly.[1] Specifications (Antoinette III) {{Aircraft specs
