The crew at Mentour Now! did a pretty good job of explaining what these switches do and precisely how their operation would square with the videos of the incident, without straying into speculation or guesswork.
That said, I believe that if the preliminary report shows that (1) there were no engine failures and (2) fuel switches were indeed set to cutoff, this has some crazy implications, as speculative as they are.

The preliminary report is expected tomorrow, but it will likely only outline the currently known information.
