## Summary

Hosts John Brunner and Alex Howe reconstruct the 1996 ValuJet Flight 592 crash, attributing the disaster to a layered failure involving expired chemical oxygen generators lacking safety caps, which ignited in the cargo hold. They analyze William Langewiesche’s account of how SaberTech mechanics, confused by inconsistent labeling of 'expired' versus 'expended' generators and a lack of provided safety caps, packed hazardous items into shipping boxes. The discussion applies Charles Perrow’s normal accident theory and Diane Vaughan’s normalization of deviance to explain how organizational complexity, 'pencil whipping' of paperwork, and systemic complacency created a tightly coupled system where accidents became inevitable.
