Preliminary NTSB Report on Dali Collision with the Francis Scott Key Bridge [pdf] (ntsb.gov)

Editorialization on the why of the title I chose:

This is reported as a preliminary report in other locations (here: https://www.ntsb.gov/investigations/Pages/DCA24MM031.aspx)

NTSB is the source, which I feel is appropriate to put in the title. It gives more weight to the report.

The initial title of the article is "Contact of Containership Dali with the Francis Scott Key Bridge and Subsequent Bridge Collapse" 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:

> 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.

So it sounds like there was an inexperienced crew and some mechanical issues.

I heard that there was some speculation around poor fuel quality, but this paragraph seems to argue against that:

> 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.
