@Teach me : double roster of crew? The crew from the other EY flt in CGK?Safety guards? Where do you find them? Do you know they have to be rated, trained, approved to fly on an aircraft? 2 months?
I don't know the solution but as Nonsense said : you find it OK to fly with the pyroman just because you haven't found him?
So YES, as myself a long-haul captain, I'm criticizing the decision to take-off again from CGK in these conditions. Find him or find a solution but do not go with such a risk unsolved!
