I was referring to your explanation "When a plane goes faster than air, it makes air-waves. When a plane goes faster than sound, it makes sound-waves."
In physics, an air wave typically refers to a sound wave. While both of your statements are true (plane makes sound-waves at both speeds), they didn't explain the sonic boom, like you did now.
> You cannot move air any faster than the speed of sound in air.
Minor nitpick, doesn't a plane traveling above Mach 1 displace (i.e. move) air faster than the speed of sound in air? :)
Right, sorry. The wave can't propagate any faster than the speed of sound -- the air itself be moved faster, but you have to do so by physically displacing it.
