Concerns Over O-Rings and Cold Temperatures
In January 1986, engineers expressed serious concerns about the performance of O-rings, critical components used in the shuttle's solid rocket boosters, particularly in cold temperatures. Thiokol's engineers had identified that these rubber gaskets become brittle and less effective at sealing joints when temperatures drop below 50 degrees Fahrenheit. Despite this knowledge, there was immense pressure on NASA to proceed with the launch of the Challenger, especially with the media attention surrounding the participation of school teacher Krista McAuliffe. Engineers like Roger Beaujolais attempted to raise alarms about the risks, but their concerns were often dismissed by decision-makers focused on maintaining the launch schedule.
