Hot Air Balloon

Hot air balloons come in many shapes and sizes.

Hot air balloons have only been around for about 30 years. The year that you are considered a Pioneer is 1975. Gas balloons have been around for hundreds of years. They are even used today but only about a hundred remain. These balloons are filled with gases that are lighter-than-air, these are the same ideas that are applied to blimbs.

The most common shape is the shere but some have made balloons called Special Shape balloons. One of the most known is the Energizer Bunny. Other shapes are the Vigin Air Plane balloon and the very basic special shape the Tetrahedron(a four sided triange).

Hot air balloons are first pumped up with cold air with a fan. When the envelope is full is full you use a burner to heat up the air which creates lift. That is how balloons fly.

You can not control the direction that a balloon goes, the only thing that you have control of is up or down. You can use this to go up and down through the sky to try to find a wind that you like but when you come down you have to remeber that the wind is going a different direction.

When you use hot air balloons you need a team of people which is called the crew and chase crew. These are the people that help you set up,inflate, rise, and chase the balloon. You needed this crew to chase the balloon through it's flight so when you land they are there ready to help assist the deflation and packing the envelope away. You can conmunicate to the chase crew using walkie talkies and a GPS to find out the speed and direction to relay to your crew so they can change directions when you do.
