Just asking...
Could the CRM comment in the prelim not have something to do with the fact that a ground engineer was on the flight deck of an aircraft rated for two-pilot operation and said ground engineer was allowed to stay on the flight deck, kinda operating as unqualified flight engineer, instead of being sent back to his seat (as a the pax he was) and strap in?
I apologise unreservedly if I have any of that wrong...I'm just trying to make sense out of what was going on the flight deck.
