A cargo ship lost power and rammed into a major bridge in Baltimore early Tuesday, destroying the span in a matter of seconds and plunging it into the river in a terrifying collapse that could disrupt a vital shipping port for months. Six people were missing and presumed dead, and the search for them was suspended until Wednesday morning. The ship’s crew issued a mayday call moments before the crash took down the Francis Scott Key Bridge, enabling authorities to limit vehicle traffic on the span, Maryland’s governor said. Here's what to know about the cargo ship Dali that crashed into Baltimore's Francis Scott Key Bridge, causing it to collapse and leaving six bridge construction workers presumed dead. If stood upright, the Dali would reach almost to the top of the Eiffel Tower in Paris or about two-thirds of the way up the Empire State Building in New York. It can carry the equivalent of almost 10,000 standard-sized metal shipping containers, and at the time of the accident was carrying nearly 4,700 containers. But while those figures are impressive, the Dali pales in comparison to the world's largest container ships, which can carry more than 24,000 containers. There are environmental and economic advantages to operating giant container ships, but their sheer size and weight make them difficult to maneuver and stop — especially when something goes wrong.
