The blast wave, depending on the size of the blast, can travel much faster then the speed of sound.

It CAN?

I guess I must have been sleeping in my high school physics class the day the teacher taught the mysterious forces that can cause that effect.

(It IS true, however, that sound WILL travel faster through a solid or liquid medium than it will thru air.)

I’ve posted the relevant info TWICE, just google blast wave speed or shock wave speed and read all about it.
