If you want to destroy aircraft loaded by submissions do not forget to include

//////////////////////////////////////////////////////////////////////////////////////////////////

    //Listen to events of every (sub)mission
    public override void Init(maddox.game.ABattle battle, int missionNumber)
    {
        base.Init(battle, missionNumber);
        MissionNumberListener = -1; //Listen to events of every mission
    }

 //////////////////////////////////////////////////////////////////////////////////////////////////
