This video from the upcoming Special Edition Ascent: Commemorating Space Shuttle DVD/BluRay takes a fascinating look at take-off from the point of view of the Solid Rocket Booster. This is absolutely awesome. Sound is a must, as the boosters become detached from the Shuttle and begin the surreal drift back towards earth. Watch to till the end to see how close both boosters end up back on the ground.
