Ever since the beginning of history man has wanted to fly.The fascination with the act of flying has led human beings to design several ways in which it would be possible.Here are a few interesting facts about how man learnt to fly

Ornithopters-imitation bird machines-were conceived as wings powered by man.Leonardo da vinci studied flight,and designed a flying machine based on the study of bat's wing's
The wings of Otto Lilienthal's biplane glider are based on da vinci's principle.
Henri Giffard's airship which used the principle that hot air could lift objects up was the first craft to fly.The above principle was also used in the zeppelin.

Wright brother's flew a plane powered by a fuel engine for the first time in 1903

Bi-planes,monoplanes and flying boats were widely used during the first World War.
Nature,howerver,provied the best model for the flying machine.The basic desgin of the helicopter was based on the dragon-fly!
One of the biggest problems in the history of aviation was that of crossing the sound Barrier(flying at or higher than the speed of sound!)the aircrafts approaching the speed sound (supersonic crafts)usually vibrated too much and broke down.the sound barrier was officially broken in 1947 by a rocket propelled US air Force plane
The Concorde was the first supersonic airplane used for commerical purposes.
Today we have planes that can fly at twice the speed of sound(hypersonic aircraft),and planes that can fly round the world without refuelling.The SR-71 blackbird, which has flown at a speed four times that of sound,is officially the world's fastest jet-powered aircraft.
