Serious question: What was the proposed course of action had they decided to cancel the launch? My (possibly wrong) understanding was that the O-ring damage only would have been apparent if they disassembled one or both of the solid rocket boosters. Was anyone seriously proposing to do this prior to the launch? The question is relevant because I’ve read conflicting sources about whether the damage to the O-ring caused by the freezing temperature was permanent. If the temperature permanently compromised the O-ring material, then a delay wouldn’t have saved the Challenger, only a disassembly of the boosters would have. However, if the O-ring performance would have recovered when brought back to a normal temperature range, then a delay could have prevented the disaster. Does anyone have any definitive sources on this?
