I think the correct Boeing reply would be: "it is not part of the certification process". So yes, loss of thrust on both engines during the takeoff phase is not really countered for in the procedures.

That does not mean that the pilots "out of habit" would have reverted to the procedure. Who would not? But in that case, the fuel control switches would be found in the RUN position post crash (if anything was left). So did they find the switches in the cutoff position, or did the action of switching got "stored" somewhere in FDM (not a specialist on these things, only to hear many times in the past that "maintenance is already aware" if we had an issue and called maintenance post flight)

Don\x92t think there is. I can only think of CVR test and erase switches on the OHP. The FCOM is also vague and says \x93continuous recording\x94, so it may be from CCS power-up.
