Why did the captain of the AF447 asked the younger copilot if his papers as a pilot were on the system that night?
It might point out that:
Dubois never flew with Bonin before and it appears the Captain was not impressed with the copilot performance during the first four hours of the flight. Bonin kept nagging the Captain to go higher to avoid the storm by going over it even when the instrument showed 36,000' was the Max at the time only. Due to weight still. Also, ATC communications with Senegal for any altitude change request was not available due to the distance (temp black out). But 1,000' higher wouldn't had done a lot of difference anyhow.
When Robert sat on the left seat the first thing he did was to adjust the weather radar which looks to me, Dubois conducted the flight in a straight line to Bordeaux kind of set of mind. Dubois had Cape Verde, Canary Islands, Portugal and Spain to choose from to compensate for any lack of fuel in the worst case scenario. Better to be late than to be dead, right? That night little things started adding up fast.
Bad all around it.
