A documentary reveals new insights into the March 2023 collapse of the Francis Scott Key Bridge after it was struck by the cargo ship M/V Dali. Transportation Secretary Pete Buttigieg recounts the chaotic event that led to the death of six road crew workers and left the cargo ship trapped under debris. Investigators suggest a power failure may have caused the accident. The extensive recovery operation involved numerous agencies working to clear thousands of tonnes of debris from the economically critical Patapsco River shipping channel.
