- The cause of the disaster was the failure of the primary and secondary redundant O-ring seals in a joint in the shuttle's right solid rocket booster (SRB). The record-low temperatures on the morning of the launch had stiffened the rubber O-rings, reducing their ability to seal the joints.

NASA's performance specification did not include the known weather conditions that occur in Florida during the winter months. A new joint design was accepted without sufficient certification and testing. Failure to accept recommendations to redesign the clevis joint. Establishing the upper limit of erosion tolerated in flight on the basis of a “com...
The space shuttle’s SRB problem began with the faulty design of its joint and increased as both NASA and contractor management first failed to recognize it as a problem, then failed to fix it, and finally treated it as an acceptable flight risk*.
There were serious ongoing weaknesses in the shuttle Safety, Reliability, and Quality Assurance Program, which had failed to exercise control over the problem tracking systems, had not critiqued the engineering analysis advanced as an explanation of the SRM seal problem, and did not provide the independent perspective required by senior NASA manage...
We cannot become complacent. We cannot be silent when we see something we feel is unsafe. We must allow people to come forward with their concerns without fear of repercussion.
