Thirty minutes later, at 1.07am, the vessel entered Fort McHenry Channel.

Numerous alarms were recorded on the ship’s bridge audio at 1.24am. Around the same time, the voyage data recorder (VDR) stopped recording the vessel’s system data, but was able to continue taping audio from an alternative power source.

Two minutes later at 1.26am, the VDR resumed recording the Dali’s system data and captured steering commands and orders about its rudder.
