There is an overly difficult trick...
First actually convincing the AI to take off with their formation then killing the leader. After that it is a toss-up whether or not the drone chooses to padlock onto you as an enemy... What makes even less sense is launching the mission HOWEVER taking off outside of the mission as a rook... "Even then a toss-up"
Sadly it's on the to-do list to have this wonderful time-killer/training tool to be rejuvinated...
