In the RLV Hangar, members of the Columbia Reconstruction Project Team look at a stack of Columbia debris shipped from Barksdale AFB, Shreveport, La. Barksdale continues to be the receiving and shipping point for Columbia materials being sent to KSC for final identification. The team is attempting to reconstruct the orbiter as part of the investigation into the accident that caused the destruction of Columbia and loss of its crew as it returned to Earth on mission STS-107.
