SAS, did you read the report? Yes there were calls, yes the collective was raised but too little too late, until right at the end when it was fully raised.
Unfortunately I don't think there is that much more to it than meets the eye. My supposition is that Copilot was looking out. Captain was looking out too because he wanted to get in and was aware of the lack of copilot's experience, and no-one was looking at the instruments properly (they were looking at the altitude, but not the airspeed).
The only thing that doesn't meet the eye is the company training and operational culture that got them there - to what extent that is a factor is unknown at this time and will probably remain so.
