How do the boys end up on the island in Lord of the Flies?
The castaway boys in William Golding's Lord of the Flies end up on the island when their plane crashes, leaving
... the long scar smashed into the jungle.
The boys are being evacuated from England, which is in the midst of a nuclear war, to Australia, where they will presumably be safe from the conflict in Europe. Although the plane may have only had engine trouble, it is almost certain that it was shot down by an enemy plane before crash-landing. A group of boys survive, but the wreckage is washed out to sea, probably taking other boys--dead and possibly alive--with it. No adults survive. Piggy claims in the first chapter that "We was attacked!", and that he saw the "other part of the plane" in flames when he looked from the window.
