Long before men learned how to fly they sent objects soaring through the air. In the Stone Age they flew kites and the early Australians invented the boomerang (a wooden V Shaped thin piece of wood). Then in the 1930’s there were several terrible accidents as air ships exploded. Also in 1853 a man named sir George Caley from England launched off a hill for the first time with the first hang glider.
In 1783 J. Etienne and Joseph M. Montgolfier inflated a big paper balloon, which was powered by hot air. It rose six feet into the air. This happened the same year that the Montgolfier brothers sent up Jean Pilate de Rozier in one of their balloons to be the first human ascent. In 1852 their Gifford a French man, flew a dirigible powered by a steam engine and a propeller In 1842 William S. Henson, a British inventor, invented an aerial steam carriage. Al Phones Penaved from France made models that were powered rubber bands. His models of airplanes and helicopters were successful. During the second half of the 19th century less attention was given to the idea of flapping the wings in the air because it would hurt the persons arms and their legs. But some way the first planes flapped their wings without hurting the person’s arms or legs. Instead gliders were built with wings. Braced by struts and wires. |

A pilot is a type of hang glider flown by a pilot hanging
underneath a wing. The hang glider is made up from metal tubes and wings. The
wings are made of fabric. The hang glider is light and is very transportational
in cars. A para glider is a type of glider, which is developed from a parachute.
The wires are made of a synthetic materiel called kevlar; this material is
stronger but liter than steel.
