:''This article is about the claims. For the aircraft and flights themselves, see Early flying machines'' Several aviators have claimed to be the first to fly a powered aeroplane. Claims that have received significant attention include: * Clément Ader in the Avion III (1897) * Gustave Whitehead in his No's. 21 and 22 aeroplanes (1901-1903) * Richard Pearse in his monoplane (1903-1904) * Samuel Pierpont Langley's Aerodrome A (1903) * Karl Jatho in Jatho biplane (1903) * Wright brothers in the Wright Flyer (1903) * Alberto Santos-Dumont in the 14 Bis (1906) In judging these claims, the generally accepted requirements are for sustained powered and controlled flight. In 1890 Ader had made a brief uncontrolled and unsustained "hop" in his Éole but such a hop is not regarded as true flight. The ability to take off unaided is also sometimes regarded as necessary. The air historian Charles Gibbs-Smith has said that, "The criteria of powered flight must remain to some extent a matter of opinion."〔Gibbs-Smith (1959)〕 Much controversy has surrounded these claims. It is most widely held today that the Wright Brothers were the first to fly successfully. Brazil regards Santos-Dumont as the first successful aviator because the Wright Flyer took off from a rail and, after 1903, used a catapult. An editorial in the influential ''Jane's All the World's Aircraft'' 2013 edition supported Whitehead.〔''Jane's all the world's aircraft'', 2013 edition, editorial.
