When any aircraft travels through the air it continuously produces air-pressure waves similar to the waves seen behind a ship when its bow ploughs through the water. When an aircraft exceeds the speed of sound, known as supersonic speed or Mach I, at about 760 miles per hour measured at sea level, it continually generates shockwaves which drop as a trail of sonic boom along its flight path. In relation to the aircraft, sonic boom sweeps backwards, away from the aircraft, in a cone shape. A person on the ground will hear the sonic boom as an explosion, similar to a clap of thunder, when the shock waves on the edges of the cone cross his location.
