When i made my first rescue mission, i was to shoot at the sticks around the crashed firebird to finish the mission.
I think that this mission is not usefull, because thereĀ“s no aliens. In fact, the Earth is populated by human bay the time the game is started. In UFO AFTERMATH, the Earth falled down and the aliens roaming for all places, this mission had more sense. But in this game, the only reason for exist, is for save your team.
So, i think that must be an automission ever, and not a playable mission.
