Breaking the Sound Barrier Pictures .
Here are some fascinating  photos of Breaking the Sound Barrier .
In aerodynamics, the sound barrier usually refers to flight at transonic speeds, between subsonic and supersonic speeds. The term came into use during World War II when a number of aircraft started to encounter the effects of compressibility, a grab-bag of unrelated aerodynamic effects. The term fell out of use in the 1950s when aircraft started to routinely "break" the sound barrier. Refer to the speed of sound for the science behind the velocity referred to as the sound barrier.
