In 1903, they built a powered airplane that had propellers and a small engine. The "Wright Flyer" airplane first flew successfully on December 17, 1903, near Kitty Hawk, North Carolina. This was the first time people ever flew a powered airplane they could control. Before that, people flew in balloons or gliders, or for a very short time in planes they could not control. The two brothers continued to make changes to their design and had a very good plane by 1905.
