Case Study – Space Shuttle Challenger
Please see the earlier section in this textbook that gives more background on this disaster.
Introduction to the Case
On January 28, 1986, seven astronauts were killed when the space shuttle they were piloting, the Challenger, exploded at just over a minute into the flight. The failure of the solid rocket booster O-rings to seal properly allowed hot combustion gases to leak from the side of the booster and burn through the external fuel tank. The failure of the O-ring was attributed to several factors, including faulty design of the solid rocket boosters, insufficient low-temperature testing of the O-ring material and of the joints that the O-ring sealed, and lack of proper communication between different levels of NASA management.

What profressional responsibilities were neglected, if any?
Should NASA have done anything differently in their launch decision procedure?
