Lofty,
I have to ask - how much NVG time do you have?
NVG's versus non-NVG's: NVG's - acuity about 20/35 to 20/45 (MIL-SPEC for AN/AVS 6). Human eye in low illumination: 20/200 to 20/400. Which do you prefer?
Come night flying with us and I'll give you a choice: Land in an unlit confined area with or without NVG's...
