When an item goes so fast through a fluid medium than the local speed of sound, a most disruptive phenomena known as a shock wave occurs. This occurs when the object shifts to a supersonic speed because before the object was moving at such a speed, the air molecules producing the sound were going faster than the object, and once the object reaches the speed of sound, the fluid molecules will be left behind the object, resulting in a traffic-jam like situation occurs in which the surrounding fluid molecules pile up and cause an almost inconceivable explosion of energy.
