Paul Hoffman on "Alberto Santos-Dumont and the Invention of Flight"

Paul Hoffman is the author of “Wings of Madness: Alberto Santos-Dumont and the Invention of Flight.”  Hoffman tells Jim Fleming that Santos-Dumont’s craft (which he tethered to a light-post outside Maxim’s while he had dinner) was a motorized hot air balloon. Santos-Dumont was the toast of Paris, although today he’s only a footnote to the history of flight.
