There are two options:

At Mach-1, you’ve reached the
speed at which sound waves
travel. Past it, you’ve broken the
sound barrier. Before 1947, that
was believed to be impossible.
Until a group of dreamers did it
in an experimental plane with
four rocket engines flown by
Captain Chuck Yeager. With
both Proof and Frosted Proof
qualities on this coin, see the
plane that was the first to fly
faster than the speed of sound.
