Zillions of billionaire characters in fiction try to buy their way out of dying by funding crazy research efforts or moving into orbit or whatever—think of John Hurt in Contact or Lionel Luthor in Smallville. Are there any examples of such figures in reality, in history? Howard Hughes types with nothing to lose?
