If you look closely at the plane underneath the top Voidraven, there are definite differences:
1) The front of the top Voidraven has a clear canopy and a bombardier - the Voidraven underneath has a forked front, not unlike the Razorwing.
2) The top Voidraven has a small wing on it's side - the one underneath doesn't.
3) The top Voidraven has two missiles on it's upper wings - the one underneath has a single larger missile.
The crew over at Bell of Lost Souls Lounge have spoken - it seems this might just be a Razorwing after all!
Oh well - a man can dream...
