What happens to the paratrooper in Lord of the Flies?

At the beginning of Chapter 6, an aerial battle takes place ten miles above the island. During the battle, a paratrooper gets shot out of the sky and lifelessly descends onto the island. The dead paratrooper's body initially lands on the side of the mountain and is carried by a heavy breeze up the mountain, until it finally rests among the shattered rocks at the top. The strings from the parachute are tangled in the trees and strain whenever the wind blows, moving the dead paratrooper's head and chest up and down. This movement gives the illusion that the paratrooper is alive. Samneric mistake the dead paratrooper's body for the beast on the island, and quickly run down the mountain to inform the rest of the boys. The dead paratrooper's body symbolizes the manifestation of evil on the island. The paratrooper's descent also alludes to Lucifer's fall from heaven.
