It demonstrates a high level of speed and efficiency in aircraft design, which can have implications for both military and civilian applications. It also pushes the limits of what is possible in terms of speed and maneuverability in flight.
The sonic boom occurs when an object travels through the air faster than the speed of sound, creating a shock wave. This shock wave produces a loud noise that is heard as a boom. So, breaking the sound barrier means exceeding the speed of sound, leading to the creation of a sonic boom.
