So, my idea, which I am proposing, is making going past Mach 1 noticeable.
As in making a Vapor Cone/Shock egg animation once the aircraft has successfully extended past Mach 1 (767 mph)
If you do actually add this, I will be a happy person. But not only that! If it's added, please consider the fact that how loud the sonic boom would be. And, PLEASE do not reuse the explosion sound effect.
I know you could whip out a cool sounding explosion effect.
Keep in mind that an actual sonic boom is 200 decibels.
If you could add this neat little thing I thought of, I'd love it to death!
It'd also be a good thing for the 'tubers to showcase as well.
