Leonardo da
Vinci who drew sketches similar to modern day helicopters established the
concept of flight. However he didn’t have the concept of aerodynamics and it
was doomed to fail.
The first man-made
flight was not actually in an aircraft but a hot air balloon by the Montgolfier
brothers in 1783. At first they used hydrogen because it was the lightest gas,
later hot air was found to be cheaper and today helium is used out of
preference.
The first
flight in an airplane, was achieved by
the Wright brothers in Kitty Hawk, North Carolina in 1903. The flight lasted
only 12 seconds.

The
development of flight remained in the developmental changes for about 30 years.
It was discovered that a major requirement was a light, reliable engine that
had good fuel economy as well. In this time the aircraft’s role began to become
wider and wider. It was used during World War 1 to deliver post. It was also
used for entertainment especially when pilots took on the challenge of long
distance flights in hope of winning prizes. In 1927 Charles Lindbergh’s
single-handed crossing of the Atlantic was a major breakthrough, which led to
the foundation o transportation of people as well as goods.
By the
time World War 2 came along the plane was at such a level that its use in the
war was extremely important. The commercial side of flying was also introduced
with the first airline, KLM, being set up in 1923. The original concept was to
use a propeller driven by a piston remained in use until World War 2 where jet
propulsion was used. Commercial airplanes continued the use of propellers
driven by gas turbines until the first commercial jet aircraft was introduced
in 1949, the de Havilland Comet. This was change the way people traveled making
international ports more accessible.
