The Avion II (originally referred to as the Zephyr (west wind) or the Éole II) was the second primitive aircraft designed by Clément Ader in 1893. Most sources agree that work on it was never completed, Ader abandoning it in favour of the Avion III that had a financial backer. Ader's later claim that he flew the Avion II in August 1892 for a distance of 100 m at a field in Satory is not widely accepted.
