Wow!  Here is something you don’t get to see every day.  Cameras mounted on the sides of the Space Shuttle booster tanks.  Notice when it breaks the sound barrier.  Cool!!! – GT

From the upcoming Special Edition Ascent: Commemorating Space Shuttle DVD/BluRay by NASA/Glenn a movie from the point of view of the Solid Rocket Booster with sound mixing and enhancement done by the folks at Skywalker Sound. The sound is all from the camera microphones and not fake or replaced with foley artist sound. The Skywalker sound folks just helped bring it out and make it more audible.
