Four lives depend on this. Two men and two women are trapped on an island. They don’t know where. They found a rescue plane with supplies for 40 people, but both pilots died and the plane lost one wing and only one engine remains. They have seen no other aircraft and no other ships.
The island’s inhabitants are hostile but the crash site is safe ground for the four survivors. They have set up camp but they want to go home.
How would you save them?
