What significant achievement did the Wright brothers accomplish in 1903?

In 1903, the Wright brothers achieved the historic milestone of conducting the first manned, powered flight. This event took place on December 17, when Orville and Wilbur Wright successfully piloted their aircraft, the Wright Flyer, at Kitty Hawk, North Carolina. This flight lasted for 12 seconds and covered a distance of 120 feet, marking a pivotal moment in aviation history.

The significance of this achievement lies in the fact that it demonstrated controlled, sustained flight with a powered aircraft, something that had not been accomplished before. This breakthrough laid the groundwork for the development of modern aviation, leading to advances in aerodynamics, engine technology, and the eventual evolution of powered aircraft design.

The other options are focused on different aspects of aviation history such as jet engines and gliders, but they do not pertain to the Wright brothers’ accomplishment in 1903, which exclusively highlights the first successful manned and powered flight.
