Who was the first person to break the sound barrier?

The first person to break the sound barrier was Chuck Yeager. This historic achievement occurred on October 14, 1947, when Yeager piloted the Bell X-1 aircraft, named "Glamorous Glennis," and reached a speed faster than the speed of sound, specifically achieving a speed of Mach 1.06. This flight marked a significant milestone in aviation history, proving that controlled, supersonic flight was possible and opening the door for advancements in aerospace technology and research.

Yeager's accomplishment has made him a celebrated figure in both military and civilian aviation history. His pioneering efforts and the technical challenges he overcame not only showcased human capability but also underscored the importance of precision engineering in flight. As a test pilot, Yeager's contributions to understanding aerodynamics and performance under various conditions paved the way for future developments in military aircraft and space exploration.
