I noticed a mass log-out last night as the daylight dwindled off into darkness in the Main Arena. I was in the midst of a long Lancaster mission, so I WELCOME the night, as its another nice way to hide.
What I wish we had were lights on the runway, or even landing lights, so I can see as I am landing...it gets a little dicey there for a few minutes with the nose up so high.
Something that's stupid, tho, is that as the area darkens, so does your map. Why? Come on, they had flashlights back then

The night aspect is a lot of fun, but if you are in a fighter, like an La7, that G's out fast, the night effect can really ruin your fun.
If we're going to have night time, lets have night time equipment on the plane, and the appropriate lighting. Its too bad so many log when it arrives, but I understand their reasons too.
