Several aviators have been claimed as the first to fly a powered aeroplane. Much controversy has surrounded these claims. It is generally accepted today that the Wright brothers were the first to achieve sustained and controlled powered flight. Brazil claims it own native citizen Alberto Santos-Dumont as the first successful aviator, discounting the Wrights because their Flyer took off from a rail and would sometimes even employ a catapult. An editorial in the 2013 edition of Jane's All the World's Aircraft supported the claim of Gustave Whitehead. Claims by, or on behalf of, other pioneers such as Clement Ader have also been put forward from time to time.
