Frankly, looking behind you with the numberpad or joystick buttons is gonna be better than any mirrors. Helps your SA too.
Yeah, My SA's pretty good, but in a plane with poor rear sight, i.e. the corsair... manually changing positions with keypad and number keys (gotta look to both right and left side...) would take longer, with less sight than just taking a peek to the mirrors...
I see how it could be a programming, FR, and gameplay disaster, but I'd love to see it implimented without these issues :]
I mean, in buffs we've already got a rear view...
