The nine stages of flight. The people and their accomplishments.




1. 400 BC- flight in China





The Daoist book called "Bapouzi", which means "Master who Embraces Simplcity" describes some ideas intrinsic to rotary wing aircraft, as early as the 4th century AD. The ideas were stemmed from observing bamboo flying toys which children in China used to play with.





2. Ancient Greece





Hero of Alexandria, an ancient Greek engineer, worked with steam and air pressure to create sources of power. He developed the "aeolipile" which used jets of steam to create a rotary motion.





3. 1484 Leonardo da Vinci- The Ornithopter and the Study of Flight





An ornithopter is a type of flying machine that attempts to fly by imitating the flapping of a bird's wings. Leonardo Da Vinci conceptualised it in the 1400s, and many others attempted in troughout the centuries but none successfully.





4. 1783- Joseph and Jaques Montgolier- The Flight of the First Hot Air Balloon





These brothers were the inventors of the Montgoliere-style hot air balloon, Globe Aerostatique. On 4 June 1783 they flew their first balloon as a public demonstration to claim its invention. The flight lasted two minutes and flew two kilometres.





5. 1799-1850's- George Cayley- Gliders





Sir George Cayley was an English engineer and one of the most important people in the history of aeronautics. In 1799 he conceptualised the modern aeroplane as a fixed-wing flying machine with separate systems for lift, thrust, and control. Many consider him the "Father of Aviation".





6. 1891 Otto Lilienthal





Otto Lilienthal, known as the "Glider King" was a German pioneer of human aviation. He followed the same experimental approach as Sir George Cayley. The hang glider he created involved a triangle control frame and a basebar. By shifting his body, he was able to change the centre of gravity, and thereby control his gliders.





7. 1891 Samuel Langley





Samuel Langley was an American astronomer, physicist, inventor, and a pioneer of aviation. Langley built a rotating arm and powered larger flying models with steam engines. His first success came in 1896 when he flew an unpiloted plane of a mile.





8. 1894 Octave Chanute





Octave Chanute was a French-born American railway engineer and aviation pioneer. He also helped the Wright Brothers, both in terms of giving them advice and publicizing their experiments. He published the very influencial book "Progress in Flying Machine" in 1894.





9. 1903 The Wright Brothers- First Flight





Orville and Wilbur Wright were two American brothers who made the first controlled, powered, and sustained human flight in 1903. They were the first to invent the aircraft controls that made fixed wing powered flights possible.
