What we know about the Baltimore bridge collapse

BALTIMORE (AP) — A cargo ship rammed into Baltimore’s Francis Scott Bridge early Tuesday, causing the span to collapse and rescuers to launch a massive search for at least six people who are missing.

Here's what we know so far about the disaster:

The operators of the Dali cargo ship issued a mayday call that the vessel had lost power moments before the crash, Maryland Gov. Wes Moore said. But he said the ship was still barreling toward the span at “a very, very rapid speed.”
