Ten years ago last month, the Space Shuttle Columbia broke up over California on its return from a routine space mission, killing all seven crew members. After months of inquiry, the Columbia Accident Investigation Board (CAIB) determined that a piece of foam broke off during the launch and damaged the shuttle's left wing.
The George Washington University's Elliott School of International Affairs holds a day long conference on "Columbia +10: Lessons Learned and Unlearned."
Former astronauts and members of CAIB discuss the specific findings of the inquiry and the lessons learned about the oversight and maintenance of complex manned and unmanned space programs.
