Vol plané (meaning "gliding flight") was a phrase first used by 19th-century French ornithologists to describe downward flight by birds; it contrasted with "vol à voile" ("soaring flight"). Around the time Orville and Wilbur Wright were promoting their latest "aeroplane" in France, the noun and the verb "volplane" soared to popularity in America as terms describing the daring dives by aviators (Fly Magazine reported in 1910, "The French flyers are noted for their thrilling spirals and vol planes from the sky"). The avian-to-aviator generalization was fitting, since the Wright brothers had studied the flight of birds in designing their planes.
