Wow. Just fecking wow.
From the upcoming Special Edition Ascent: Commemorating Space Shuttle DVD/BluRay by NASA/Glenn. It's 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 faked or replaced with foley artist sound. The Skywalker sound folks just helped bring it out and make it more audible.
