Two weeks before Charles Lindbergh's famous flight, a pair of French aviators attempted a similar feat. Their brave journey might have changed history -- but they disappeared en route. In this week's episode of the Futility Closet podcast we'll follow the flight of the "White Bird" -- and ponder what became of it.We'll also examine a proposal to build hippo ranches in the Louisiana bayou in 1910, investigate historical outbreaks of dancing, laughing, and other strange behavior, and present the next Futility Closet challenge.
