Yep,it's been long understood that,striking a vacuum will telegraph an intense pressure spike in a fully-compressible medium,all the way to the planet's surface.We'd hear it,if not for the fact that God tuned our ears such that they cannot detect the constant supersonic shockwaves coming through the atmosphere.
That's why all space craft immediately burn up in space,due to the skin friction up there.If you've ever seen crews returning to Earth,that's all faked.No one's ever been to space.It can't be done because of the solar wind.
