In January 1986, NASA engineers knew the Space Shuttle Challenger's O-rings had never been tested in freezing temperatures. They recommended delaying the launch. Managers asked: Could the engineers prove it was unsafe? They couldn't-they could only say the system hadn't been designed for these conditions. Under pressure, the engineers withdrew their recommendation. The next morning, Challenger broke apart 73 seconds after launch, killing all seven astronauts.
