Aviator's Day is observed in Brazil every October 23, commemorating the first official flight of Alberto Santos-Dumont, a pioneering figure in aviation who is celebrated as the “father of flight” and a national hero. Santos-Dumont, born in 1873, moved to Paris in 1891, where he developed an interest in balloons and dirigibles before shifting his focus to heavier-than-air aircraft. His notable achievement occurred on October 23, 1906, when he successfully flew a powered heavier-than-air machine, a flight verified by the Aéro-Club de France. Despite spending much of his life in France, his contributions to aviation are deeply revered in Brazil, leading to the establishment of this day to honor his legacy. On this day, various events and celebrations may take place to recognize the advancements in aviation and Santos-Dumont's impact on the field.
