Which sound barrier?
The sound barrier refers to the physical limit of how fast an object can travel through the air before it experiences a sudden increase in aerodynamic drag and a corresponding increase in the generation of shock waves, which produce a sonic boom. This barrier is commonly associated with the speed of sound, which is approximately 767 miles per hour (1,235 kilometers per hour) at sea level. Breaking the sound barrier was a significant milestone in aviation history, and it was first accomplished by Chuck Yeager in 1947. Today, supersonic aircraft and military jets routinely travel faster than the speed of sound.
