System Crash (2008)

Our most vital systems -- energy, transportation, finance and communications -- depend on complex, inter-connected global networks. They're fast, efficient and uniquely vulnerable to major failure or attack. In "System Crash", we go behind the scenes and look at how big, critical systems work and how they can fail in spectacular and sometimes devastating ways.
