Although the full details of the Wright Brothers' system of flight control had been published in l'Aerophile in January 1906, the importance of this advance was not recognised, and European experimenters generally concentrated on attempting to produce inherently stable machines. Short powered flights were performed in France by Romanian engineer Traian Vuia on 18 March and 19 August 1906 when he flew 12 and 24 metres, respectively, in a self-designed, fully self-propelled, fixed-wing aircraft, that possessed a fully wheeled undercarriage. He was followed by Jacob Ellehammer who built a monoplane which he tested with a tether in Denmark on 12 September 1906, flying 42 metres. On 13 September 1906, the Brazilian Alberto Santos-Dumont made a public flight in Paris with the 14-bis, also known as Oiseau de proie (French for "bird of prey"). This was canard configured with a pronounced wing dihedral, and covered a distance of 60 m (200 ft) on the grounds of the Chateau de Bagatelle in Paris' Bois de Boulogne before a large crowd of witnesses. This well-documented event was the first flight verified by the Aéro-Club de France of a powered heavier-than-air machine in Europe and won the Deutsch-Archdeacon Prize for the first officially observed flight greater than 25 m (82 ft). On 12 November 1906, Santos-Dumont set the first world record recognized by the Federation Aeronautique Internationale by flying 220 m (720 ft) in 21.5 seconds. Only one more brief flight was made by the 14-bis in March 1907, after which it was abandoned. In March 1907, Gabriel Voisin flew the first example of his Voisin biplane. On 13 January 1908, a second example was flown by Henri Farman to win the Deutsch-Archdeacon Grand Prix d'Aviation prize for a flight in which the aircraft flew a distance of more than a kilometre and landed at the point where it had taken off. The flight lasted 1 minute and 28 seconds.
==== Flight as an established technology ====
Santos-Dumont later added ailerons between the wings in an effort to gain more lateral stability. His final design, first flown in 1907, was the series of Demoiselle monoplanes (Nos. 19 to 22). The Demoiselle No 19 could be constructed in only 15 days and became the world's first series production aircraft. The Demoiselle achieved 120 km/h. The fuselage consisted of three specially reinforced bamboo booms. The pilot sat in a seat between the main wheels of a conventional landing gear whose pair of wire-spoked mainwheels were located at the lower front of the airframe, with a tailskid half-way back beneath the rear fuselage structure. The Demoiselle was controlled in flight by a cruciform tail unit hinged on a form of universal joint at the aft end of the fuselage structure to function as elevator and rudder, with roll control provided through wing warping (No. 20), with the wings only warping "down". In 1908, Wilbur Wright travelled to Europe, and starting in August gave a series of flight demonstrations at Le Mans in France. The first demonstration, made on 8 August, attracted an audience including most of the major French aviation experimenters, who were astonished by the clear superiority of the Wright Brothers' aircraft, particularly its ability to make tight controlled turns. The importance of using roll control in making turns was recognised by almost all the European experimenters: Henri Farman fitted ailerons to his Voisin biplane and shortly afterwards set up his own aircraft construction business, whose first product was the influential Farman III biplane. The following year saw the widespread recognition of powered flight as something other than the preserve of dreamers and eccentrics. On 25 July 1909, Louis Blériot won worldwide fame by winning a £1,000 prize offered by the British Daily Mail newspaper for a flight across the English Channel, and in August around half a million people, including the President of France Armand Fallières and the Prime Minister of the United Kingdom David Lloyd George, attended one of the first aviation meetings, the Grande Semaine d'Aviation at Reims. In 1914, pioneering aviator Tony Jannus captained the inaugural flight of the St. Petersburg-Tampa Airboat Line, the world's first commercial passenger airline. On 30 July 1914, Tryggve Gran made the first flight across the Northsea from Cruden Bay in Scotland to Reve in Norway in a Blériot XI in 4 hours and 10 mimutes, a distance of 465 km. Historians disagree about whether the Wright brothers patent war impeded development of the aviation industry in the United States compared to Europe. The patent war ended during World War I when the government pressured the industry into forming a patent pool, and major litigants had left the industry.
==== Rotorcraft ====
In 1877, the Italian engineer, inventor and aeronautical pioneer Enrico Forlanini developed an unmanned helicopter powered by a steam engine. It rose to a height of 13 metres (43 feet), where it remained for 20 seconds, after a vertical take-off from a park in Milan. Milan has dedicated its city airport to Enrico Forlanini, the airport is also named Linate Airport, as well as the nearby park, the Parco Forlanini. In Milan he also has an avenue named after him, Viale Enrico Forlanini. The first time a manned helicopter is known to have risen off the ground was on a tethered flight in 1907 by the Breguet-Richet Gyroplane. Later the same year the Cornu helicopter, also French, made the first rotary-winged free flight at Lisieux, France. However, these were not practical designs.
