He's the chief engineer on another merchant vessel. He's mentioned between (03:00) and (03:21) in the video in post #65.

April 10 NTSB before Congress Committee. Preliminary report will not be out until first week of May.
(I should also note, which isnt in this video, a third worker was recovered several days ago. Not sure if it was previously posted. so 3 still not recovered as of this time.)
NTSB statements:
9:30 she atlks a bit about Office of Highway Safety is looking at pier protection for new bridge.

NTSB statements:
Article: we're actually
4:27 our investigative team
is on the vessel as we speak. we
downloaded the vdr, The Voyage data
recorder, on scene and then we removed
the vdr in order to download the
past 30 days in our lab to learn from
that.
we formalized parties to the
investigation. I'm pleased to say that
Grace Grace ocean and Synergy have
4:52
become parties to our investigation as
well as the US Coast Guard Maryland
Transportation Authority and the
association of Maryland Pilots
Article: 5:37 our investigators are on
scene. they needed the assistance of
Hyundai, who is the manufacturer of
equipment in the engine room, to download
data from the electrical power system
and look at the circuit breakers. that is
where our focus is right now in this
investigation.
of course that's
preliminary, it could take different
roads, different paths, as we continue
this investtigation. it's very early
but we're collecting that data
Article: 6:39
6:43 we have had the manufacturer of equipment in
the engine room to look closely at
the electrical power system. we're
continuing to look at that.
we've asked for additional assistance from the
manufacturer who returned from overseas
this week with experts to look at the
circuit breakers
9:30 she atlks a bit about Office of Highway Safety is looking at pier protection for new bridge.
Article: 9:25
office of Highway Safety team is really
9:25
focused on peer protection ction looking
at the original bridge design and how it
would be built today under today's
standards I expect uh regardless of some
erroneous press report from Bloomberg
that our preliminary report will not be
out until the first week of May

or you could consult the footnotes in the NTSB report
Article: WASHINGTON (March 20, 2025) — The National Transportation Safety Board recommended Thursday that 30 owners of 68 bridges across 19 states conduct a vulnerability assessment to determine the risk of bridge collapse from a vessel collision, part of the ongoing investigation into the collapse of the Francis Scott Key Bridge in Baltimore.
The NTSB found that the Key Bridge, which collapsed after being struck by the containership Dali on March 26, 2024, was almost 30 times above the acceptable risk threshold for critical or essential bridges, according to guidance established by the American Association of State Highway and Transportation Officials, or AASHTO.
Over the last year, the NTSB identified 68 bridges that were designed before the AASHTO guidance was established — like the Key Bridge — that do not have a current vulnerability assessment. The recommendations are issued to bridge owners to calculate the annual frequency of collapse for their bridges using AASHTO's Method II calculation.
Today's report does not suggest that the 68 bridges are certain to collapse. The NTSB is recommending that these 30 bridge owners evaluate whether the bridges are above the AASHTO acceptable level of risk. The NTSB recommended that bridge owners develop and implement a comprehensive risk reduction plan, if the calculations indicate a bridge has a risk level above the AASHTO threshold.
The Marine Investigation Report is available online.
When the NTSB releases a report, it's a good idea to link to it alongside the video of the briefing. It's usually as easy as going to ntsb.gov and looking at the top item.
Was there anything interesting in the Q&A? I only watched the beginning of the briefing (which is reflected in the written material).
