The expedition soon ends in disaster: the "Pensacola" breaks in two and crashes into the ocean during a storm. Frisky participates in the rescue of the expedition by aircraft carrier. He now gets a leave of absence from the Navy to pilot a Fokker Trimotor transport aircraft for Rondelle's next attempt at the South Pole. This proves too much for Helen. When she is unable to get Frisky to change his mind, she gives him another sealed letter (to be read when he reaches the Pole), but this time it says that she is divorcing him and will ask Jack to marry her.
