That sounds like a whole bunch of fun, not!!! Why do I think this thread could end up with a bunch of Sea King dits?. .. .Mine, not quite so bad - night troop move up a fjord on NVG. Inevitable snow storm arrived, so the only visual reference I had was a single sodium street light about 2 miles ahead. No viz of the surface at 150', no viz of either side of the fjord 1/2 mile to R & L, and no climb option. Fortunately, I was flying with a Kiwi bloke who was pretty cool about it all, and we made the pick up, and got out again OK.
