The Grande Semaine d'Aviation de la Champagne was an aviation meet held near Reims in France during August 1909. It was the first international public flying event and was seen both at the time and by later historians as marking the coming of age of heavier-than-air aviation. Almost all of the prominent aviators of the time took part, and the 500,000 visitors included Armand Fallières, the President of the French Republic and the British Chancellor of the Exchequer, David Lloyd George.
