Who was the first man to break the sound barrier?

The first man to break the sound barrier was Chuck Yeager. This historic achievement occurred on October 14, 1947, when Yeager piloted the Bell X-1, a rocket-powered aircraft. He reached a speed of Mach 1.06, which is approximately 700 mph at the altitude of 43,000 feet. Yeager's successful flight marked a significant milestone in aviation history, demonstrating that controlled flight could be accomplished at speeds exceeding that of sound.

Chuck Yeager's accomplishment paved the way for advancements in supersonic flight and influenced aerodynamics research and aircraft design. His role as a test pilot and his daring flight have made him a legendary figure in aviation, often cited as a symbol of human courage and innovation in the field of aerospace engineering.
