Night Witches? Other WWII?
Looks like War Stories is finished, and is geared toward Operation Overlord and beyond, using the 101st as the unit that everyone is in. Could also be fun. I'm not too particular, though I love the on-again, off-again; combat/air base divide of a pilot's group.
Years (and years!) ago I ran a GURPS game where the players were the aircrew of a Beaufort Ftr/Bomber based in Cairo - bomb runs & anti-shipping & hvy fighter sweeps, but also clandestine resupply of the LRDG, a little cthulhu-esque mummy action, spies in Cairo, etc. Great fun.
