There are many competing claims for the earliest powered, heavier-than-air flight. The first recorded powered flight was carried out by Clément Ader on October 9, 1890, in his bat-winged, fully self-propelled fixed-wing aircraft, the Ader Éole. It was reportedly the first manned, powered, heavier-than-air flight of a significant distance () but insignificant altitude from level ground. Seven years later, on 14 October 1897, Ader's Avion III was tested without success in front of two officials from the French War ministry. The report on the trials was not publicized until 1910, as they had been a military secret. In November 1906, Ader claimed to have made a successful flight on 14 October 1897, achieving an "uninterrupted flight" of around . Although widely believed at the time, these claims were later discredited.
