Comment Why do they want to climb? (Score 1) 132
It's probably not the (only) reason for the crash, but I don't understand why they want to climb in this situation. The Air France flight did the same IIRC.
They can't hope to outclimb a CB and at FL390, the difference between stall speed and VNE gets pretty damn small.
Maybe it was too late to do anything else, but then they really need to improve their weather forecast in the area.
