As for getting the cabin secure we also really struggled and it has nothing to do with breaks as all cabin secures are 20 mins out on long haul flights.
If the CSD was not part of the (usual) service before the loss of one crew member, what did the CSD do during the time for securing the cabin? How is that different now, since the 16th November? Would be interested to know, as would many others, I'm sure.
