Preliminary NTSB Report on Dali Collision with the Francis Scott Key Bridge [pdf]

Editorialization on the why of the title I chose:<p>This is reported as a preliminary report in other locations (here: <a href="https:&#x2F;&#x2F;www.ntsb.gov&#x2F;investigations&#x2F;Pages&#x2F;DCA24MM031.aspx" rel="nofollow">https:&#x2F;&#x2F;www.ntsb.gov&#x2F;investigations&#x2F;Pages&#x2F;DCA24MM031.aspx</a>)<p>NTSB is the source, which I feel is appropriate to put in the title. It gives more weight to the report.<p>The initial title of the article is &quot;Contact of Containership Dali with the Francis Scott Key Bridge and Subsequent Bridge Collapse&quot; which is too long for HN. I felt that the outcome (collapse) was not important to include in the title, and the rest was just shortening in order to make the title more approachable.

I think these sentences sum up most of the article:<p>&gt; The [...] blackout [the day before the bridge collision] was caused by the mechanical blocking of the online generator’s exhaust gas stack. The second blackout in port [the day before the collision] was related to insufficient fuel pressure for the online generator.<p>So it sounds like there was an inexperienced crew and some mechanical issues.<p>I heard that there was some speculation around poor fuel quality, but this paragraph seems to argue against that:<p>&gt; Fuel-sample analysis results indicated that the [...] fuel [...] complied with international standards and regulations. The test results did not identify any concerns related to the quality of the fuel.
