I believe this image sums this wish up nicely.
CreditLocation: High above somewhere.
Obstacles: None (or perhaps a giant, unmoving artifact dirigible or two, AKA, the reason ships come here, possible King of the Hill or CK reason)
Floor: None. Boundary wind blows you back up.
Layout: This map is not very tall, and is divided into thirds. The middle third is clear sky, while the top and bottom thirds are dense cloud. Nothing to hide behind but water vapor and hope.
Play: Ships spawn in the upper or lower cloud layer, and stealth around before popping up/down to attack/capture a point.
Optional fun that can't be done because the mechanics don't currently support it: randomly placed invisible mines in the cloud layers that explode with a bight blue flash and damage everything on your ship and give away your location for a second along with the invariable shout of "God damn lightning!" from the pilot.
