Not sure if this was discussed or mentioned in here yet:
Runway lighting (night time).
Searchlights.
Cockpit lighting. Didn't LW fighters have a red light?
Bomb blast/explosion lighting (also hit sprite flashes and fires)
Rocket launch lighting.
Sparks and other nifty fire effects when landing with gear up or emergency "flopping" as you skid across the runway.
Town lights at night (ie, light through windows). Just a different texture, no lightmap required.
Dynamic fire lighting for damaged/destroyed structures.
Drop tanks still containing fuel exploding on contact after jettisoned
A better looking sun! Jane's WWII Fighters, as cheesy as it was, had an excellent looking sun. AH's sun at sunset/sunrise looks like it's fizzing out.
