In which decade did the Wright Brothers make the first powered flight?

Orville Wright and Wilbur Wright, together known as the Wright brothers, were American aviation pioneers generally credited with inventing, building, and flying the world's first successful motor-operated airplane during the 1900s. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, 4 miles south of Kitty Hawk, North Carolina, at what is now known as Kill Devil Hills. The brothers were also the first to invent aircraft controls that made fixed-wing powered flight possible.
