It's difficult to imagine that just a century ago, airplane contrails were never seen in the sky.  There was no airline industry to speak of.  In 1900, airplanes did not even exist.  Now we live in a world that relies on safe and reliable air travel. What was the genesis of our massive airline infrastructure?  Professor Greg Jackson from the "History That Doesn't Suck" podcast joins Infrastructure Junkies to tell the story of Wilbur and Orville Wright - brothers from Dayton Ohio who had the vision of a flying machine before any such machine existed.  How did the Wright Brothers transform a vague vision into the idea to fly off of the side of a huge hill in Kitty Hawk, North Carolina?  How did that experiment go?  And how did they get from a rudimentary hang glider to reliable air transportation and war machines?  Join Professor Jackson and Infrastructure Junkies to find out!
