Columbia Accident Investigation Board - Author Collection

The Columbia Accident Investigation Board (CAIB) was convened by NASA to investigate the destruction of the Space Shuttle Columbia during STS-107 upon atmospheric re-entry on February 1, 2003. The panel determined that the accident was caused by foam insulation breaking off from the shuttle, forming debris which damaged the wing; and that the problem of "debris shedding" was well known but considered "acceptable" by management. The panel also recommended changes that should be made to increase the safety of future shuttle flights. The CAIB released its final report on August 26, 2003.
