Connect Shuttle hardware failures with decision processes

Challenger and its seven crew members were lost on January 28, 1986. The Rogers Commission identified failure of the right solid rocket booster field joint’s sealing system, allowing hot gases to escape. Cold conditions and the joint’s design and behavior were central to the technical account.

The commission also examined how information and concerns were handled before launch. Its findings included communication failures and a flawed decision process. A summary limited to “an O-ring broke” omits why the known concerns did not produce an adequate barrier to launching.

Columbia and its seven crew members were lost during reentry on February 1, 2003. Foam shed from the external tank during launch had struck and breached the left wing’s thermal protection. Hot entry gases then entered the damaged structure. The damaging event and the final loss occurred at different phases of the mission.

The Columbia Accident Investigation Board also addressed organizational conditions, assessment of foam risk and the handling of concerns and requests for additional information. Previous flights with foam shedding did not establish that another strike would be harmless. Surviving an earlier departure from expectations is not the same as proving the condition acceptable.

Connect the physical and organizational accounts

For a fictional launch review, engineers report that a seal has not been tested in forecast conditions. The question is not simply whether anyone can prove a disaster will happen. Decision-makers need evidence that the required performance is supported, and unresolved uncertainty must be communicated accurately.

Corrective action — open definition can involve hardware redesign, testing, independent review and changes in authority or communication. None is validated solely by being written into a policy. Compare implementation and later practice with the investigation’s findings, while keeping the lost crews and their work visible rather than turning these events into trivia.
