MILESTONES IN AVIATION HISTORY
THE EARLY EXPERIENCES
Dated back as early as 400 BC, an unknown
Greek scholar had build a wooden pigeon that
was able to fly in circle. How exactly he did it is
The early Chinese built kites that were big
enough to enable people to ride on them. They
were early gliders, but had to have strings
EARLY ATTEMPTS TO FLY
In 1500 Leonardo da Vinci came up with early
design of flying machine, known as
The early attempts emulate the flight of the
birds, with flipping wings, all attempts failed as
our hands are not strong enough to flap the big
Montgolfier brothers demonstrated in 1783
using balloons about 100 feet in diameter,
filled with hot air was able to travel more than
However the flight lack the directional control,
leaving it to the mercy of the blowing wind.
The problem of directional control was
overcome by making the balloon elongated and
providing the powered thrust.
The most famous of the balloon generation was
the Zeppelin in 1930s. Zeppelin was making
trips across the Atlantic with the cruise speed
The era ended with the tragedy of Hindenburg,
when the balloon caught fire on landing.
In 1804, Cayley, a British built the first
successful glider. This is the sparked up the
idea that flying can be achieved by using a fixed
wing design and a power unit to push the glider.
The first man to fly was a boy of unknown
BIRTH OF GLIDER
Around 1890, a German Lilienthal, developed
the first controllable glider.
He was fascinated by the idea of flight based
on the flying birds. He wrote a book on
aerodynamics in 1889 and his text was used
by the Wright Brothers as the basis for their
After more than 2500 flights, he was killed
when he lost control of his glider.
WORKS IN USA
Samuel Langley who started to build the
foundation of the present airplanes
He knew that a power unit was required, and
based on the technology available at that time,
he built an airplane powered by steam.
In 1891, his model just managed to lift of the
ground. He was frustrated and gave up
