In the RLV Hangar at KSC, members of the Columbia Restoration Project Team show Shuttle Program Manager Ron Dittemore (third from left) and Ralph Roe, with the Orbiter Work Group at JSC, a piece of Columbia debris. The team is examining pieces and attempting to reconstruct the orbiter as part of the investigation into the accident that caused the destruction of Columbia on its return to Earth from mission STS-107. To date, four shipments have arrived from Barksdale AFB, Shreveport, La., the collection point for debris.
