Couple of questions about NVG (about which I admit I know nothing; never flown in a role which used them)
- Do they add to or detract from pilot's abaility to see/focus on indications/controls indside the cockpit (in partcular the electrical power selector above/behind his head?
- Where do NVGs draw their power from, and would this source be interrupted by the double flame out?
- The interim report says pilot and 2 x police observers were equipped with NVG: has anyone seen evidence as to whether they were actually wearing/using the NVG at the moment of the accident?
