If they know the FO, etc. will come out at exactly 2 hours +/- a few minutes for his break, all they have to do is start some diversion in the galley over some stupid coffee or other trash, get the FA's distracted and wait for the door latch to move. The forward galleys should be OFF LIMITS to ALL passengers for a period of time when the FO's can do their business. This is a TRIAL RUN. Expect many more. I have no doubt that this was a PROBE of the defenses..........
Nothing could comes from the France.
