History of The "Balloon"

6214601.jpg

On the 19th of September 1783, Pilatre De Rozier, a scientist, launched the first hot air balloon called '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 first manned attempt came about 2 months later on 21st November, with a balloon made by 2 French brothers, Joseph and Etienne Montgolfier. The balloon was launched from the centre of Paris and flew for a period of 20 minutes. The birth of hot air ballooning!!!

 

Just 2 years later in 1785 a French balloonist, Jean Pierre Blanchard, and his American co pilot, John Jefferies, became the first to fly across the English Channel. In these early days of ballooning, the English Channel was considered the first step to long distance ballooning so this was a large benchmark in ballooning history.

 

Unfortunately, this same year Pilatre de Rozier (the world's first balloonist) was killed in his attempt at crossing the channel. His balloon exploded half an hour after takeoff due to the experimental design of using a hydrogen balloon and hot air balloon tied together. (no need to worry! Technology assures safety!).

 

 

Science Behind it

      If you actually need to get somewhere, a hot air balloon is a fairly impractical vehicle.You can't really steer it, and it only travels as fast as the wind blows. But if you simply want to enjoy the experience of flying, there's nothing quite like it. Many people describe flying in a hot air balloon as one of the most serene, enjoyable activities they've ever experienced.

 

      Hot air balloons are also an ingenious application of basic scientific principles.  Hot air balloons are based on a very basic scientific principle: warmer air rises in cooler air. Essentially, hot air is lighter than cool air, because it has less mass per unit of volume. A cubic foot of air weighs roughly 28 grams (about an ounce). If you heat that air by 100 degrees F, it weighs about 7 grams less. Therefore, each cubic foot of air contained in a hot air balloon can lift about 7 grams. That's not much, and this is why hot air balloons are so huge -- to lift 1,000 pounds, you need about 65,000 cubic feet of hot air.
