Any one knows why we hear sounds of fighter aircrafts after it passing us

Since this is due to the unnatural behaviour of sound waves. Since fighter aircrafts move with the speed more the speed of sound waves. the sound waves are restricted to the back side of the aircraft, bye a machcone. But in normal aircrafts we here the sound well in advance. since its speed is less the speed of sound. so sound wave travell well in advance to normal subsonic aircraft.
