@Yoae I don’t think you should feel too much pressure to resolve these quickly. There will be official reports coming out in the coming weeks and months, and I don’t see any harm in keeping many of these open until verified by a credible source, for example the coast guard or NTSB investigations.
It's too late for me to edit it now, but in the "overload trip mechanism" option, I meant to refer to an "over SPEED trip mechanism", as described here.
Hope you don't mind me adding all the options, @Yoae - I'm also not seeing the option to resolve them (not to say that I'd resolve any at this time, just to say that I think you're the only person with power to resolve) so I hope I'm writing these clearly enough that you'll be able to settle them at close.
@Jwags I closed out one possibility. It is hard to verify anything about this incident so far. If you have any reliable sources with answers, please let me know.
