Secret Weapons of the Looftwarfers, Secret Weapons of the, um, Narnians? Nibbelung? NoGoodNiks? Nanobots? Narcocapitalists? Nasties? Noncombatants?
Secret Weapons of the Nachtjägers (a total conversion for Secret Weapons of the Luftwaffe - one of the finest, only rivaled by the Russian Front and surpassed by Lucky Strikes).
Jumping in a little late but that mod is probably one of the few that I did NOT download for the SWOTL.
The only "sim" that comes to mind is the board-game Nightfighters published by GMT games. It covers practically the entire length of WWII, covering the impact that technological advances had on the night battles. I recall when flying WB there was at least one night fighting phase I took part in, flying a Bf110 and I had to get vectored in towards B-24s subbing as Liberators by another player in the control tower acting as GCI.
The problem with night fighting is that it's a lot different from day fighting and it's a totally different world. It's almost a cross between modern air combat with the radar and chaff flying around and a submarine sim. Most of the time, the player would be staring at a radar screen trying to make sense of what he's seeing, listening to GCI vectoring him in and everything else would be black with flak bursts, search lights and the occasional tracers streaking by.
