Just broken the sound barrier.
So you can relax now.

And switch on your in-jet stereo...
would you hear anything

No, Chuck Yeager never had an in-jet stereo.

But, if he did, and if the noise was low enough,
he'd have no problem whatsoever. He's traveling
faster than sound relative to the air OUTSIDE his
jet. The air inside his cockpit, relative to him,
is not moving at all.


Oh wow... The speed of sound, c, is added to the speed of the jet, v.
But you don't have to be Chuck. Concorde has been born, flown and
died since then.
