@amazeifystore: It wasn’t simply that the rubber “froze.” At about 36°F, Challenger’s booster-joint O-rings were less resilient and couldn’t seal quickly as the joint shifted at ignition. Hot gas escaped and damaged the joint. The takeaway: test critical seals at the temperatures they’ll actually face.
