what does simon find on the mountian-top?

Simon awakens and finds the air dark and humid with an approaching storm. His nose is bleeding, and he staggers toward the mountain in a daze. He crawls up the hill and, in the failing light, sees the dead pilot with his flapping parachute. Watching the parachute rise and fall with the wind, Simon realizes that the boys have mistaken this harmless object for the deadly beast that has plunged their entire group into chaos. When Simon sees the corpse of the parachutist, he begins to vomit. When he is finished, he untangles the parachute lines, freeing the parachute from the rocks. Anxious to prove to the group that the beast is not real after all, Simon stumbles toward the distant light of the fire at Jack’s feast to tell the other boys what he has seen.
