Question: Information:  - The Astra C was a 1912 French single engine biplane , manufactured by Société Astra at Villacoublay . In 1913 , the Astra CM Hydro - avion three - seat floatplane version was used to make the world 's first scheduled passenger - carrying flights .  - The Astra-Torres airships were non-rigid airships built by Société Astra to a design by Spaniard Leonardo Torres Quevedo in France between about 1908 and 1922. They had a highly-characteristic tri-lobed cross-section rather than the more usual circular cross-section. This was the result of moving most of the blimp's bracing wires inside the envelope in an attempt to minimise drag. Early Astra-Torres airships could be trimmed by moving the entire gondola fore-and-aft.  - Société Astra des Constructions Aéronautiques was a major French manufacturer of balloons, airships, and aeroplanes in the early 20th Century. It was founded in 1908 when Henri Deutsch de la Meurthe purchased Édouard Surcouf's workshops at Billancourt. Its most significant products were the Astra-Torres airships, but beginning in 1909, the firm also produced Wright brothers heavier-than-air designs under licence. In 1912, these were supplanted by Astra's own designs, the Astra C and CM.  - Henri Deutsch de la Meurthe (1846, Paris  1919) was a successful French petroleum businessman (known as the "Oil King of Europe") and an avid supporter of early aviation. He sponsored a number of prizes to encourage the development of aviation technologies, including the Grand Prix d'Aviation and the Deutsch de la Meurthe prize.  - The Wright brothers, Orville (August 19, 1871  January 30, 1948) and Wilbur (April 16, 1867  May 30, 1912), were two American brothers, inventors, and aviation pioneers who are generally credited with inventing, building, and flying the world's first successful airplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft on December 17, 1903, four miles south of Kitty Hawk, North Carolina. In 190405 the brothers developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.    Given the information, choose the subject and object entities that have the relation of 'instance of'.
