Space Shuttle Orbiter Enterprise is rolled back as part of the exercise designed to help clear the way for the liftoff of its sister ship Columbia.

Space Shuttle Orbiter Enterprise, mated to a 15-story-tall external propellant tank and twin inert solid rocket boosters on top of a Mobile Launcher Platform, is rolled back to the Vehicle Assembly Building from Lauch Complex 39's Pad A July 23 at the completion of nearly three months of fit and function checks at the shuttle launch site as part of the exercise designed to help clear the way for the liftoff of its sister ship Columbia. The massive Crawler Transporter began moving its 11 million pound load the 3.5 miles from pad A to the VAB at 10:23 a.m. and reached the doorway to High Bay 1 at 3:48p.m. following serveral days of fit checks of modified extermiable platforms in the assembly bay, the nonlaunchable shuttle will be destacked. Enterprise will be returned to Rockwell International and stripped of parts for integration into orbiter destined for space, while the external tank and solid booster will be returned to their respective prime contractors and refurbished for use on a later shuttle mission.
