Leonardo da Vinci
People have dreamt of flying for centuries. From the Greek Mythological times
to Leonardo da Vinci's sketches of a plausible helicopter, people have always
attempted to fly.
Roger Bacon
The first attempts of a heavier than air flight were based upon the structure
and movements of a bird. Roger Bacon used this ideology in the eighteenth century
when he proposed that men should use flapping wings in order to get airborne.
Although Roger Bacon's idea failed, it did not discourage others from continuing
to try.
Sir George Cayley
In the nineteenth century, Sir George Cayley, who was a scientist and an inventor, noticed
that birds were able to glide through the sky for long periods of time without flapping
their wings. He then continued on by building a pair of gliders, whose wings were shaped
like those of birds. Men running against the wind launched the craft. The craft made a few
short flights but could not carry anybody along.
Jean-Marie Le Bris and Otto Lilienthal
The first person to make a man-carrying glider was a Frenchman, Jean-Marie Le
Bris. He succeeded on making the short flight in 1855. Following Jean-Marie's
man accompanying flight, Otto Lilienthal, who was a German inventor and studied
the gliding flight of birds, built a glider with curved wings, opposed to the
traditional flat wings. He constructed a glider in 1891, which had bat shaped
wings made of delicate wood spars and was covered with silk. The amazing thing
was that he could control his flights shifting his weight to the desired side
using his legs. After making around 2000 flights, he was killed in 1896.
