Aircraft Adjacent tto Attacked Hex?

[richvalle]

I think the change, the +2 for air attacks is a change from the 3rd Edition, was to make aircraft more effective. Before, unless something like a P-47 arrived, there wasn't much to worry about. Now aircraft can be effective. You worry about a Me-109, and dread a P-47 when the +2 is involved.

Yep, this.  Being above is still being adjacent.
