April 6 in aviation: the first flight of the Freman III aircraft; launch of the Space Shuttle Challenger STS-41-C.

On April 6, 1909, the first aircraft designed entirely by the Anglo-French air pioneer, Henri Farman, flew for the first time to Bouy, France. Named either HenrI Farman III, or Freman III, or - because it represents a new departure - HF1, the biplane was the first aircraft to incorporate practical ailerons attached to the rear edges of the wings.
