That reminds me, seeing Ian's screenshots. Following some beta testing, it became obvious that this scenery really requires at least one airport completed before it is released. I tend to use saved flights to find my way around, rather than take off from one of the airfields every time I test the scenery, but the testers found it a bit disconcerting that the starting airports are a bit -- defaulty -- and tend to detract from the scenery.
This will delay the release a bit, how much I just don't know, but we should still be talking a few weeks.
