Columbia Accident Investigation Board Final Report, Volume 1

On February 1, 2003, the space shuttle Columbia disintegrated over Texas mere minutes before landing, killing seven astronauts. This is the definitive account of why. The Columbia Accident Investigation Board spent seven months examining every fragment of the wreckage, every second of telemetry, every decision that led to catastrophe. What they found was not a single failure but a cascade of warnings ignored, warnings that began 16 days earlier when a piece of insulating foam struck the orbiter's left wing during launch. Through meticulous reconstruction, the Board traced the chain of events that allowed managers to dismiss engineering concerns, bypass safety protocols, and convince themselves that the crew was safe when the vehicle was already fatally damaged. This report is simultaneously a forensic investigation, a memorial to Rick Husband, Michael Anderson, Ilan Ramon, Kalpana Chawla, David Brown, William McCool, and Laurel Clark, and a ruthless accounting of how organizational culture can poison even the most well-intentioned institutions. It reshaped NASA forever.
