I'm under the impression aircraft is supposed to be repaired once they reach the hangar... But they don't; at first, I wasn't paying attention and thought maybe the alien ships were just too dang strong for my poor Stiletto, but, as it turns out, the engineers appeared to have been slacking off or something, but, the aircraft health was never being regained because... The engineers didn't repair the dang thing! Is there an option I should know about in the aircraft interface? Or this this some weird bug?
