The "effect" you speak of is not part of the mission file. As such, it can't be recreated using AlliED or any other mission editor. The effect is in the XWA executable. Any mission that you put as the 2nd mission in the game will result in AI control of the players craft. So, if you want to "recreate" this effect, you need to put your mission in place of the 2nd mission.
