Good morning from Meziesblog! Here we bring you NTSB’s timeline of events from the Baltimore Bridge collapse.

00:39 – VDR recorded ship’s departure from Seagirt Marine Terminal

01:07 – Ship had entered the Fort McHenry Channel

01:24 – Ship was on a heading under way on a true heading of approx 141 degrees at a speed of 8 knots/9.2mph

01:24:59 – Numerous audible alarms recorded on ships bridge audio – at same time, the VDR stopped recording sensor data, but continued to record audio using redundant power source

01:26:02 – VDR sensor data recording resumed. Steering commands and rudder orders were recorded on the audio during this time

01:26:39 – Pilot made general VHF (very high frequency) call for tugs in the vicinity to assist. At the same time, the power of association dispatcher phoned the Maryland Transport Authority (MDTA) duty officer regarding the blackout

01:27:04 – Pilot ordered the Dali to drop the port anchor and ordered additional steering commands

01:27:25 – Pilot issued a radio call over the VHF radio reporting the Dali had lost all power and was heading towards the bridge. Around this time MDTA data shows the following also occurred: the duty officer radioed to their units that were already on scene due to construction on the bridge – one on each side of the bridge – and ordered them to close the traffic on the bridge. All lanes were then shut down by MDTA

01:29 – Ship’s speed was just under 7 knots/8pmh and from 01:29:00 to 01:29:33 the ship’s audio recorded the collision of the bridge

01:29:39 – Pilot reported the bridge down over the audio to the coast guard
