BALTIMORE (AP) — A container ship lost power and rammed into a major bridge in Baltimore, causing the span to buckle into the river below. The collapse plunged a construction crew into the dangerously cold waters. Rescuers pulled out two people, but six others were missing and presumed dead. The ship’s crew issued a mayday call moments before the crash took down the Francis Scott Key Bridge. The Maryland governor said the mayday enabled authorities to limit vehicle traffic on the span. The ship struck one of the bridge’s supports, causing the structure to collapse like a toy. It tumbled into the water in a matter of seconds
