Ship lost propulsion, warned of collision, CISA report says
An unclassified Cybersecurity and Infrastructure Security Agency report said the container ship Dali "lost propulsion" as it was leaving port and warned Maryland officials of a possible collision.
The crew notified officials that they had lost control, the report said.
"The vessel notified MD Department of Transportation (MDOT) that they had lost control of the vessel and an allision with the bridge was possible," the report said. "The vessel struck the bridge causing a complete collapse."
The waterway into and out of the port has been closed and there is no other route into the port, which is the second busiest port in the mid-Atlantic.
