I was thinking it would be cool to have some mobile or stationary lighting that could be popped in to a parking spot. I know it's not necessarily realistic, as airports usually have their own lighting, but nights are really dark. It's often hard to see what's going on. The headlights from the baggage loaders provide some light, but it's not a lot.
Edit: Also to note, I usually do Cargo Ops, that are far away from the main terminals, on some tarmac somewhere.
