 History 
Humans first built devices to fly in the air a long time ago. In the sixth century, Yuan Huangtou from China created a kite. Some primitive types of parachutes and gliders were also created in North Africa.

The modern age of aviation started on November 21, 1783, when the Montgolfier brothers flew in their hot air balloon. Airships followed. On December 17, 1903, the  Wright brothers flew the first flight in an aeroplane which was heavier than air; their invention is known as the first aeroplane.

Military aircraft became somewhat important in World War I. In the 1930s airliners began carrying many passengers. Jet engines began flying in fighter aircraft in World War II and in airliners in the 1950s.
