@Sasless, I agree mostly, however, there is blame to be put on multiple organizations in this case, including the Norwegian Air Force AND Leonardo Helicopters... Lack of training from one, or rather lack of relevant training, lack of knowledge between different variants etc from LH. Lack of continuity of flying from the Air Force, some of the OT&E pilots had not really flown in a year. or more... But read through the whole thing that jimjim1 posted. it may give some clarity. But blaming the crew alone for this fu$kup is a little rich.
We all make mistakes, just try to minimize the impact of such mistakes...
