In what year did the Wright Brothers improve their designs for longer flights?

The Wright Brothers significantly advanced their designs for longer flights in 1905. This year marked a crucial turning point in their aeronautical pursuits, as they developed the Wright Flyer III, which was a substantial improvement over their earlier models. The Flyer III featured better control mechanisms, a more powerful engine, and a greater wingspan, enabling longer and more stable flights. During the course of 1905, the Wright Brothers achieved several remarkable flights, with the longest being over 39 minutes, indicating a major leap in their capabilities and proving that sustained controlled flight was indeed possible. This year is often recognized as the first time powered flights could be sustained and controlled for significant durations, marking a pivotal moment in aviation history.
