How do the boys reach the island in "Lord of the Flies"? Are the boys from the choir in the same school as the non-choirboys?
Golding leaves the wider context of the "Lord of the Flies" story deliberately vague. But it seems that there are two - or perhaps more - different sets of boys all on the same plane, being taken to an unknown location, when the plane crashes or is shot down on the island. Not all the boys are from the same school.
The boys believe that
The plane was shot down in flames. Nobody knows where we are.
Piggy, earlier, also claims
When we was coming down I looked through one of them windows. I saw the other part of the plane. There were flames coming out of it.
Golding, however, remains specifically vague about what has happened - though seems to imply that the boys' plane was shot down in some wider war (of which the Navy Officer at the very end is a representative). But where was their plane going?
Perhaps the boys are being evacuated; remember that the novel was written very shortly after the Second World War, during which many English children were evacuated, and sent to live in the country while bombing raids endangered them in the city. Perhaps they are on some sort of trip. Unfortunately Golding doesn't specify.
