Английская Википедия:Ader Avion II
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 the 1893.[1] 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.Шаблон:Citation needed
