On January 28, 1986, the NASA shuttle orbiter undertaking a mission broke apart 73 seconds into its flight, killing all seven crew members: five NASA astronauts, one payload specialist, and a civilian school teacher. The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39 a.m. EST. The failure was caused by the failure of O-ring seals used in the joint that were not designed to handle the unusually cold conditions that existed at this launch. This disaster was widely publicized and the details of the event are used as a case study to understand workplace ethics and engineering systems.
