Introduction:
The hot air balloon is one of the
oldest and most successful flight technologies; it was once used to carry
passengers to travel across the region. Then it was used for military purposes,
nowadays it is mostly used for tourism.
Almost three centuries ago the hot air
balloons were invented and they were tested on animals, On the 19th September
1783 by Pilatre De Rozier, a scientist who built and launched the
first hot air balloon ever and he named it 'Aerostat Reveillon'. The passengers
were a sheep, a duck and a rooster and the balloon stayed in the air for a
grand total of 15 minutes before crashing back to the ground.
The hot air balloons have started
an era in transport where scientists started looking on air travel and space
travel. Scientists started building air balloons that can go higher than
100,000 feet with a capsule (where the passengers will be) to balance the
air pressure in the balloon so it may flew as higher as it
can get.
Unfortunately they are not the
most popular travel methods nowadays. Scientists are going more on wings and
jet airplanes although this technology was of the most powerful invention ever
at that period in mankind history.
