Société Astra
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 product was the Astra-Torres airship designed by Spanish engineer Leonardo Torres Quevedo, 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.
