Yeah, watched this today too. Kudos to them for the absence of 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.
Officially, now, it was the switches being moved to CUTOFF. They were put back to RUN in 10 seconds, after RAT deployment, with engine 1 spooling back up to thrust just before impact. Switches survived the fire damage in that position, so the detents appear to have been fully functional. Crazy implications indeed. The CVR transcript isn’t in the preliminary report, but the little bit referenced indicates one pilot asking the other why they performed a cutoff followed by the other responding that they didn’t.
