AIRCRAFT - A device that is used or intended to be used for flight in the air. The two main classifications of aircraft are lighter-than-air and
heavier-than-air.
Lighter-than-air is applied to all aircraft which sustain their weight by displacing an equal weight of air (example aerostats, airship , sky lanterns).
Heavier-than-air aircraft's works on the principle of Newton's third law of motion, it requires some external power source to propel forward.
AIRCRAFT HISTORY :
5th Century BC - Kite ( The first form of aircraft).
13th Century - Roger Bacon ( Told that air could support a craft just like water supports boats).
16th century - Leonardo da Vinci ( Developed airscrew and parachute).
1783 - Joseph and Jacque Montgolfier (Developed first hot air balloon).
1804 - George Cayley (First model glider).
1891 - Lawrence Hargrave (Created a rigid-wing aircraft with flapping blades operated by a compressed-air motor).
1903 - Wright Brothers ( First heavier-than-air aircraft).
