2. Hot air balloons are the oldest SUCCESSFUL human-carrying flight technology.
They have 2 parts: the bag or envelope and the gondola or wicker basket. They
also need a source of heat. The heated air inside the envelope makes the balloon
buoyant, which makes it rise. It can fly to extremely high altitudes.

3. Parts of a hot air balloon

4. As early as 200 A.D., the Chinese used small hot air
balloons to pass visual signals between military units.
Two French brothers, Jacques-Etienne, aged 38, and
Joseph-Michel Montgolfier, aged 43, developed the
first hot air balloon. They were papermakers who
were born in Annonay, France.

5. In June, 1783, the Montgolfier brothers launched
their hot air balloon. It was a paper lined linen
balloon, filled with hot smoke from a straw fire. It
rose 6,000 feet. This balloon did not carry any
passengers. In Sept, 1783, King Louis XVI
witnessed the first balloon with passengers – a
duck, a rooster and a sheep.

6. The Montgolfier brothers noticed that wood chips
float over a fire and they realized that heated air
collected inside a lightweight paper or fabric bag
would cause the bag to rise. This led to their
experimentation of capturing heated air in a balloon

7. Balloons were used during wartime for military
observation during the Civil War. They were also
used to carry mail out of Paris, over German lines
during the Franco-Prussian War.

8. Today, balloons are mainly used for recreation
