The tragedy was so devastating that NASA suspended flights for 33 months. What went wrong? How could such a precisely designed and built machine fail? A Presidential Commission that investigated the disaster included the Nobel Prize winning physicist Richard Feynman and astronaut Neil Armstrong. During one of the most profound moments of the investigation, the Nobel Laureate demonstrated, with a rubber O-Ring and a glass of ice-cold water, that the disaster was the direct result of the failure of the O-Ring, a component costing less than $10, because it did not have the capability to expand as required at low temperatures.

The probability of anyone being killed by a bolt of lightning is one in eight million. The probability of being killed in a road accident is one in four thousand. Has this simple statistic made you a more ca
