In 1945, a U.S. Army transport plane crashed in New Guinea, leaving three survivors marooned in the island's mountainous interior. Injured, starving, and exhausted, the group seemed beyond the hope of rescue. In this week's episode of the Futility Closet podcast we'll describe the plight of the stranded survivors and the remarkable plan to save them. We'll also reflect on synthetic fingerprints and puzzle over a suspicious notebook. Intro: What's the shortest possible game of Monopoly if each player plays optimally? Omen or crated inkwell.
