at least we know now why it crashed
It was an all female crew. We’ve known why it crashed from day 1. Why? It was an all female crew.
I know a guy who flies for a major airline. For a long time he flew regional jets for a small operator for that major.” They hire them young to build hours. Usually the right-seater does most of the flying, but in this case I doubt that the co-pilot was actually landing the plane. The wind & ice would have required the experienced, left-seat pilot to perform that landing.
