All flying models that are up high, from both sides, are placed together on a side table or suitable location away from the game. They are assumed to be wheeling around each other and aware of each other's presence above the battlefield. They may attack each other with 'glancing blows' as described below, but note that they are not affected by psychology in respect to other models which are high. This is because of the fleeting nature of aerial warfare, where it is easy to wheel out of danger and avoid confrontation.
