From the article: "During several earlier shuttle missions, disaster did everything it could to crawl into the shuttle launch system and turn it into tumbling flaming wreckage. The primary O-rings on those flights suffered severe erosion from superheated gases, sometimes accompanied by lesser erosion. And the erosion had occurred after launch temperatures much higher than on this freezing Florida day -- 53 degrees was the lowest launch-time temperature up to that time. The booster engineers felt helpless. For months, they had been studying the O-ring seal problem. They knew a disaster was coming, but no one stepped forward and said, 'Stop this train until it's fixed.'"
