What is the setting in the opening pages of the novel, Wreckage?

The private jet serves as a method of transportation from Fiji Island to Adiata for the second part of the Carlton Yogurt dream vacation contest. It is piloted by Kent, attended by Theresa, and used by Lillian, Margaret, and Dave. The jet has seen many years of usage, and appears aged on the outside despite a comfortably remodeled interior. The jet is outfitted with an emergency inflatable life raft, life vests, and a first aid kit. The jet also has wireless internet capacity and private television screens embedded into the seats. The jet is the setting for the first several chapters of the novel and ceases to be a setting upon its sinking.
