A Moment of Science
Speed isn't the only factor affecting the sonic boom. Size and altitude also plays a vital role.
In October of 1947, U.S. Air Force Pilot Chuck Yeager became the first person to fly a plane faster than the speed of sound.
Remarkably, when someone cracks a whip they actually make the tip of the whip move faster than the speed of sound. The crack is actually a miniature sonic boom.
