When someone flies to an enemy field and has air superiority it is reaally difficult for the defenders to kill that someone. The vulch factor, air advantage all play a prominent part.
With tanks it is totally opposite. If you take 4 tanks to a field.. someone can easily rapid spawn and defend that field. For that reason I think that the Vhangers should be a couple miles away from the airfield (possibly a 5 min drive). This would allow for engagements outside of the airfield vicinity and also allow for some dramatic field battles.
