I remember one mission, trying to sneak back to base, after accomplishing the main and secondary missions,, but there was this pesky YaK-38 sniffing around, just above me. He knew I was there, but his radar couldn't find me. I remember flying as low and slow as I could, to keep that detection bar as short as possible. I was more worried about stalling than being seen. That RTB lasted forever!! It is an awesome game; try it. For a land-based game of equal complexity and fun, try Seal Team.
