Empire-
Breath. Count to 10. Relax. Fluff a pillow. When you are ready to listen, read further (and the above posts).
The plane exists on your system, if you are flying the latest version (have you played AH lately online, including H2H? Yes, then you have the latest version).
Can you fly it?
No.
Why not?
It is not enabled by HTC.
I think you are looking for the plane in your in-game menu. You won't find it there because it has not been enabled yet. The plane exists in your files, on your hard drive, but is not accessible for gameplay until HTC enables it. THERE IS ABSOLUTELY NOTHING YOU CAN DO FOR NOW BUT WAIT UNTIL HTC DECIDES TO TURN IT ON. You won't see it in any in-game menu until then.
Read this very carefully, and relax. You are not getting the shaft. No one is out to get you. You are not missing out on anything. You aren't being hosed. Nobody is flying this plane right now (they did at the con mission, but becaue HTC enabled the plane for a little while) Keep reading the boards, and you will hear more about updates and when new planes will be enabled. AS far as I know, this is the only one that is already on our machines, but not available for gameplay yet.
Breathe some more....
