NTSB investigator Marcel Muise held a press conference to reveal the data on the DALI’s black box, also known as the Voyage Data Recorder (VDR).
• Approximately 6 hours of VDR data was provided to NTSB, with the time period between 12am-6am
• By regulation, VDR’s are required to record 30 days of history
• The quality of audio varies due to background noise and alarms — additional analysis will be performed at NTSB Lab to improve its quality.

TIMESTAMPS
• 12:39am, the ship departed
• At 1:07am (kek) the ship entered the channel
• At 1:24am, VDR Sensor Data CEASED recording…
— the VDR Audio continued recording being on a redundant power source.
• 1:26am, VDR resumed recording sensor data. No redundancy?
• 1:26am, the pilot made a general VHF for tugs in the vicinity to assist
• 1:27am, pilot ordered the DALI to drop the port anchor and ordered additional steering commands.
• 1:27am, the pilot issued a radio call reporting the DALI had lost all power
• At this time, MDTA duty officer radioed two of their units that were already on the bridge, due to construction, and order them to close traffic.
• 1:29am, the ship made contact with the bridge
• 1:29am, the DALI Pilot made contact with the Coast Guard to report the bridge down

MAIN TAKEAWAYS….
• The VDR Sensor Data is “missing” 2 minutes of data? Do you know how important this data is?
The VDR Sensor data records critical Information related to the operation of a vessel:
— ship speed
— engine RPM
— ships course and heading
— rutter angle
— as well as information on the ship's communications with other vessels, the ship's crew, and any external systems or equipment.
This does not look good…
