Since it was attempt to clone "Crimson Skies" action and even story mood, I was following this indie project. I bought it early on Desura. Early game "betas" was so-so. I think it is using "Ogre" engine, if they didn't swap recently. Now I have to wait till evening (to get to my home PC) to try this kinda "final" version.

P.S.: sorry about this news being a bit off-topic, but it is aerial shooting game, and also tribute to some old game, so I think it fits here
