In my experience, risk matrices are created to make decisions based on risk. If the risk is unacceptable then it's... unacceptable!! Why have an unacceptable part of the matrix if it is not going to be used? And how can "a threat to the vehicle - not a direct threat to the crew" be possible. If it is a catastrophic risk to the vehicle then it has to be catastrophic to the crew--period. I must be missing something here. If NASA is truely making the decision as presented in the media then they are wrong, no matter how it is stated. I’m not sure I understand the gray area here.
