Muise then shared that the “VDR sensor data ceased recording. The VDR audio continued to record using the redundant power source.”

“VDR resumed recording sensor data, and during this time, steering commands and rutter orders were recorded on the audio,” added Muise.

Muise continued, “The ship’s pilot made a very high-frequency radio call for tugs in the vicinity to assist. About this time, the pilot dispatcher phoned the Maryland Transportation Authority duty officer regarding the blackout.”

He concluded his statement by adding that “The ship’s speed over ground was recorded at just under 7 knots. From this moment to approximately 1:29:33, the VDR audio recorded sounds consistent with the collision of the bridge.”
