Eighteenth Century Ballooning :: European Europe History
Eighteenth Century Ballooning    à          à          In a time where the skies are full of aircraft, it is hard to   à    imagine a time when air travel was nothing but a dream.  That was   à    just the case during the early eighteenth century.  The dream of flight   à    was so concentrated on winged flight that ballooning was actually and   à    accidental discovery.  The shift to alternate opportunities to fly   à    occurred in 1766 with the discovery of hydrogen.  Henry Cavendish   à    discovered the gas he coined the ââ¬Å"inflammable gas.â⬠  At that time this   à    meant that the gas was highly combustible, unlike todayââ¬â¢s   à    interpretation of inflammable.  What made this gas so important was   à    the fact that the gas was much lighter than the atmosphere.  The   à    lighter gas would give the balloon lift in the surrounding atmosphere,   à    hopefully taking a human along with it.  The new discovery brought a   à    lot of excitement to the pursuit of air travel.  The discovery began to   à    move forward in 1774 with Joseph Priestlyââ¬â¢s publication of   à    ââ¬Å"Experiments and Observations with Different Types of Air.â⬠  This   à    paper explored uses of the gas and further explained its properties for   à    future experimentation. In 1777, the paper was translated into   à    French and read by Joseph Montgolfier.  The paper inspired   à    Montgolfier to further explore the possibilities of the gas.  Montgolfier   à    and his brother Etienne began experimenting with the gas in hopes of   à    coming up with a device to give them flight.  This became a reality in   à    1786 when the two brothers were able to fly small cloth and paper hot   à    air filled balloons.  This was the small and modest beginning to hot air   à    balloon flight.            à          The brothers had some complication to work out with the first   à    flights being experimental.  They used dense smoke from burning   à    chopped wool or damp straw to lift the balloon.  The smoke idea most   à    likely came from a concept left over from the medieval times.  They   à    believed that smoke had more of a virtue of lightness, and lighter   à    meant that the balloon had a better chance of flight.  Another   à    possibility is that the brothers believed that the dense smoke would   à    simply be better contained in the balloon.  Some individuals even   à    believe that the brothers used thick smoke to conceal their ideas.
