    Researchers from Lehigh University are working on a way for an aircraft to be in perpetual flight. Nobel laureate John Strutt first put forth the theory of perpetual flight in 1883, when he observed how pelicans could fly without beating their wings.

    Airplanes have come a long way since the early 20th century. Flying thousands of miles without stopping is so common that it's no longer remarkable.

    Now, researchers from Lehigh University are working on a way for an aircraft to be in perpetual flight.

    With funding from Lehigh University and the National Science Foundation, the team of researchers is putting together an unmanned aircraft that can fly using jet stream winds.

    They built a 21 foot long wing made of carbon fiber composite that can fly in jet streams 20 thousand feet up in the air at speeds of up to 300 miles per hour.

    Using the different wind speeds the aircraft will need little or no fuel to fly and can theoretically stay aloft indefinitely.

    This kind of flying is called dynamic soaring, and has been used by the United States Air Force and NASA on the L-23 Blanik, a large aircraft that was able to use dynamic soaring to execute flight maneuvers.
