Baltimore Bridge Collapse: The Call That Stopped Traffic

The Key Bridge collapse in Baltimore began with a label on one wire inside the containership Dali's switchboard. Twenty months later, the NTSB's final report explained how a heat-shrunk label kept that wire from seating, why a 984-foot ship lost power twice in four minutes, why the bridge had never been checked against a ship strike, and why the warning that stopped every car never reached the six men working on the bridge. The official final report (NTSB MIR-25-40): https://www.ntsb.gov/investigations/A... Chapters: 00:00 The label 01:39 Who was on the bridge? 03:34 Four minutes 08:11 The ship that kept blacking out 10:02 Why the wire wouldn't go in 11:07 Nobody called the crew 11:50 Why the bridge fell 13:32 Whose fault?
