Only part way through the report, but I get the impression that no real detailed approach brief was made, had attention been paid to the route guide all the information was there, on the map Blackrock 282', in the notes Blackrock 310'. Unfamiliarity played a role, Captain had not been there for 15 years and Co-pilot not for some time, all the more reason for attention to the route guide. Then again there is operating at an unsocial hour and attendant human factors. NVGs may have been nice, but they were not relevant to the accident in my view.
Most interested in seeing what crab has to say, being in the business.
