This story starts out as just a conflict about a new bomb being tested on a South Sea island. The natives of the island refuse to leave the island where "our fathers and our father's fathers are buried." It turns out they have ulterior motives. The reason for the title "The Castaways" finally becomes clear in the surprise ending. A good story written by Ernest Kinoy. (from "The Critical X Minus One" by Jim Fanisher)
