Search for cause of Baltimore bridge accident: Black box read - ship reported emergency. Video footage from Reuters journalist Matthew Keys suggests that a technical failure may have been the trigger for the disaster.

The ship sounded the alarm via radio and asked for help from a tugboat a few minutes before it crashed into the Key Bridge. Federal officials presented the evaluations at a press conference on Wednesday. At this point, the operation in Baltimore had already been declared a pure recovery mission. For those people who are still missing in the cold water, there is no longer any chance of survival.
