On the 23rd day, Crimp disappears; Tommy eventually discovers his dead body. When Peggy and Pete go looking for Tommy, he leads them to Crimp, killed by a poison dart. Pete orders Peggy to take Tommy to safety while he covers their retreat. He is killed by the unseen natives. The remaining survivors board the now-repaired airliner, but as the engines turn over, the oil line in one engine starts leaking. Bill and Joe patch it, but inform the others that the patch will fail some time after takeoff, leaving only one running engine. As a result, the aircraft can only carry four adults and Tommy across the mountains. Vasquez suddenly grabs a pistol and announces that he will choose who goes, since he is doomed either way and is therefore the only one without bias. While the repairs are being made, Professor Spengler tells Vasquez that he and his wife volunteer to stay, as they have only a few years left anyway. Judson, on the other hand, tries to bribe Vasquez by offering to pay for a top lawyer.
