Ever the voice of practicality and reason on the island, Piggy first offers up the notion that a rescue might just be a long time coming. He originally suggests this in an aside to Ralph at the very beginning of the novel. Ralph offers the opinion that the people at the airport must know their location, and Piggy corrects him:
"Not them. Didn't you hear what the pilot said? About the atom bomb? They're all dead" (14).
Piggy's grim view of reality does not shake Ralph's total faith in being rescued, and the topic is one of the first up for discussion at their first tribal meeting. The boys decide to ascertain if they are indeed stranded on an uninhabited island, and when they return, Ralph attempts to address their status.
In this particular tribal council meeting, Piggy pessimistically points out to the entire tribe of boys that they may not be rescues for a very long time. Using the same argument as he did with Ralph, Piggy tries to make his suggestion sink in with his fellow tribe members:
"'Nobody knows where we are,' said Piggy. He was paler than before and breathless. 'Perhaps they knew wehre we was going to; and perhaps not. But the don't know where we are 'cos we never got there'" (34).
In the frist Chapter Piggy introduces the idea to Ralph, "Not them. Didn't you hear what the pilot said? About the atom bomb? They're all dead." Thus no one knows about them and it's unlikey for them to get rescued.
maybe Ralph because he keeps on saying that if there isn't a fire, we won't be saved
