FULL AFTERNOON COVERAGE: Baltimore bridge collapses after ship hits it - people fall into water

A mayday call made by the cargo ship that struck the Francis Scott Key Bridge helped stop traffic and prevent more casualties.

The cargo vessel "Dali" lost power and collided with the Francis Scott Key Bridge in the Patapsco River early Tuesday morning. The bridge, which makes up part of the Baltimore Beltway, collapsed shortly after impact.

Officials say Dali sent out a mayday call as it drifted helplessly toward the bridge. Gov. Moore credited workers on the ground who received the mayday call and subsequently shut down traffic.
