When used as a case study on MCC/CRM training (and referring to their existing understanding of the chain of events), most students initially feel that the accident was beyond the control of the crew. After evaluating the data in the report, they always (in my experience) come round to the view that the crew rushed the decision making and diversion, mismanaged their own workshare and workload and failed to make full use of their available resources (cabin crew etc.).
And I suppose that the students in your MCC/CRM training are magically exempt the environmental capture involved in being on the course, and thus don't come round to the conclusion that the crew did not perform well because they know it's what's expected of them in their environment...
Could you demonstrate to us precisely what benefit the industry has derived from CRM and MCC, please?
No? Thought not. No-one can, because it hasn't.
