I'll make you one if you tell me what you want in it.
Lrg , Med ,Small airfield? Maybe a Port or Carrier task group.
How far away from target? (Miles)
Or I could just place a Large Airfield at the center of the Terrain with alt. of 10,000ft like you said and then set enemy targets:
To the North: Airfields (Lrg, Med and Sml).
To the South: Vehicle Field, Port and Carrier Task Group.
To the East: Strategic Targets (HDQ's and a City).
To the West: Factories (Ack, Ammo, Bar, Oil and Radar).
