Wright Brothers Day is celebrated on December 17, 2023. Wright Brothers Day is a United States national observation. It is codified in the US Code, and commemorates the first successful flights in a heavier than air, mechanically propelled airplane, that were made by Orville and Wilbur Wright on December 17, 1903, near Kitty Hawk, North Carolina.
The Wright brothers were two American brothers, inventors, and aviation pioneers who were credited with inventing and building the world's first successful airplane and making the first controlled, powered and sustained heavier-than-air human flight.
From 1905 to 1907, the brothers developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.
