The moment the plane pierced the sound barrier

The extraordinary phenomenon below happens only in moments when the plane pierces the sound barrier and is like it passes through a wall.

This unique image takes place before a plane reaches 1,200km / h to break the sound barrier.

When a plane reaches high speed, a cluster of cone-shaped steam will form and become bigger and bigger until an explosive sound is heard. The moment the plane breaks the sound barrier is very fast, occurring within 1/1000 of a second.
