Tim Howard heads to Fort Monmouth, New Jersey for the story of a WWII hero whose feats of navigation saved hundreds of lives. The hero? A pigeon named G.I. Joe. Museum Curator Mindy Rosewitz fills in the details. Professor Charles Walcott  helps Tim delve into the mysteries of how pigeons pull off these seemingly impossible journeys--flying home across hundreds of miles of unfamiliar terrain. Then, Dr. Lera Boroditsky tells us about a language in Australia in which a pigeon-like ability to orient yourself is so crucial...you can't even say hello without knowing exactly which direction you're facing. And finally, Jad and Robert talk to Karen Jacobsen, aka "the GPS girl," about her own navigational abilities.
