Shaock Only at supersonic speed

Message(about aircraft prasence downstream) waves go
upstream at the speed of sound.

But Aircraft goes more than the speed of sound.(supersonic)

Before upstream air get the message about aircraft prasence,
air encouter the aircraft.
No time to adjust the airflow,Hence Shock!
