Hi everyone,

Just wanted to share with you guys something that i only learnt today while surfing youtube for videos. I had never known that when an object breaks the sound barrier, it would create a cone of vapour, which is also known as the Prandtl–Glauert singularity. This is caused by the pressurised water vapour turning into liquid, or you can even call it instant clouds.

Here's a video that shows the effect.



You also realise that because the plane has been travelling at or near the speed of sound, the sound comes in all together as a massive boom, which is also known as a sonic boom.

Hope you guys were as amazed as me.
