Exactly but I don't think he read the links. Engineering designed system with triple tolerance. o rings had triple the corrosion, but management said it's still within tolerane, right? Triple corrosion but we have triple tolerance, so we're even right? Engineering knew pretty well that wasn't the case, and that is not how tolerance works. Feynman in his reports goes a long way to list all the overrides management did and how much the whole shuttle program was built on wishful thinking. http://science.ksc.nasa.gov/shuttle/missions/51-l/docs/rogers-commission/Appendix-F.txt http://science.ksc.nasa.gov/shuttle/missions/51-l/docs/roger...
