Do you know about history of Hot-Air Balloon ?

Made in 1784, soon after the Montgolfier flight this engraving shows the proliferation of balloon designs.

In an early test, a Montgolfier balloon lifts from its hear source, restrained by men on the ground.

History :

At 1:45 pm., November 25, 1783 in courtyard of the château da la Muerte on the outskirts of Paris, the balloon constructed by brothers Joseph-Michale (1740-1810) and Jacques-Étiennebde Montgolfier d'ADLANDES the flight high over the city lasted for 25 minutes and came to the ground on the Butte-aux-Cailles,10 miles(16km) from where it had started.

The Montgolfier's inspiration came from watching a fire burning and speculating as to the "force" that caused the sparks smokes and embers to rise. They constructed a large envelope from taffeta, lit fire beneath the opening and watched as it rose to the ceiling. The experiments grew grander in scale until on September 19, 1782 they were called to conduct a royal demonstration in Versailles. King Louis 14 and Queen Mary Antoinette witnessed the first passenger carrying air flight-albeit with a sheep,a duck and a rooster in the basket of balloon. 

The 8 minute flight saw the Montgolfier's creation rise to a height of 1500 feet before running out of fuel and landing safely two miles distant.

In spite of their success the brothers had still fail to understand the science that underpinned their work. They believed it was smoke from the burning wool and straw that cause their balloon to rise. In fact the balloon Rose because the property of their changes when its temperature is altered. The heated air inside the balloon became lighter than the colder Air on the outside causing it to ascend.

The two brothers were honoured by the French Académie des sciences and both were credited with further important inventions in their careers.
