A single loose wire on a cargo ship caused a power outage that led to the Baltimore bridge collapse that killed six highway workers last year, a National Transportation Safety Board (NTSB) report released Tuesday found.
The big picture: "This tragedy should have never occurred," NTSB Chair Jennifer Homendy said at a Tuesday hearing on the agency's findings into how the Dali ship crashed into the bridge, leading to its collapse that blocked full access to the Port of Baltimore's main shipping channel until June.
