The Flying Machine
 
    When Leonardo da Vinci invented the Flying Machine, he intended it to be used by just one person at a time.  The aviator would lie in the wooden framework, in order to work the wings.  The two moveable wings were attached by pulleys and stirrups.  The pilot of the Flying Machine would pull on the wings simultaneously in order to create lift.  Once in the air, theoretically, the pilot would simply shift his body weight in order to turn the machine.  This invention went hand-in-hand with da Vinci's Parachute.  Even though that this invention never got off the ground, it was a steady foundation for many other models of flying machines.  The Wright brothers are probably thankful for da Vinci's invention, because without it, we may not have the types of airplanes, jets, and helicopters that we do today.
