Come on all you nay sayers: grasp as hard as you can on to one accident PRELIMINARY report of a pilot trying to find a reason why he hit terrain, and lets ignore the HUNDREDS of night unaided disorientation accidents shall we?
What was his training levels on NVG? Which NVG was he using, how good was the cockpit mod? What risk management was applied to the flight? What is the formal risk management requirements of the operator? What level of supervision was involved? What was the forecast weather and moon state? Were these formally considered in the operator's risk management process? What was the pilot's circadian cycles up to? What was the visibility? Why did terrain impact occur after de-goggling? Why did he not affect an instrument recovery? Did his training, recency, currency, etc require this? What was the physiological aspects of the pilot? Stress at home? Cold? Flu? Job stress? Blah blah blah.....
or instead of considering all these (and more) we could simply just throw away NVG and blame them! must be their faultmusn't it?
You know, there is even disorientation accidents during the day: but we haven't stopped flying during the day have we?
