He is the Captain and the safe custody of the flight is in his hands. When he re-entered the cockpit he should have shown his authority when he seen things were being so poorly managed.By the so called pilots sitting in 0A&0B.
As PIC and Captain of the aircraft he has a duty of care to all personnel within his charge. If that means telling Bonin or Robert to get out of that******* seat now!!! then so be it. Ultimately he did nothing.....
Over 2 minutes and 30 seconds in the cockpit and all he did was watch it all happen with no input to improve the situation.
Its a damning indictment of Air France Cockpit Management Procedures and Policy.
