First Manned Hydrogen Balloon Flight
Only a few days later, at 13:45 on December 1, 1783, professor Jacques Charles and the Robert brothers (Les Frères Robert) launched a new, manned hydrogen balloon from the Jardin des Tuileries in Paris, amid vast crowds and excitement. The balloon was held on ropes and led to its final launch place by four of the leading noblemen in France, the Marechal de Richelieu, Marshal de Biron, the Bailli de Suffren, and the Duke of Chaulnes. Jacques Charles was accompanied by Nicolas-Louis Robert as co-pilot of the 380-cubic-metre, hydrogen-filled balloon. The envelope was fitted with a hydrogen release valve, and was covered with a net from which the basket was suspended. Sand ballast was used to control altitude. They ascended to a height of about 1,800 feet (550 m) and landed at sunset in Nesles-la-Vallée after a flight of 2 hours and 5 minutes, covering 36 km. The chasers on horseback, who were led by the Duc de Chartres, held down the craft while both Charles and Robert alighted.
Charles then decided to ascend again, but alone this time because the balloon had lost some of its hydrogen. This time he ascended rapidly to an altitude of about 3,000 metres), where he saw the sun again. He began suffering from aching pain in his ears so he 'valved' to release gas, and descended to land gently about 3 km away at Tour du Lay. Unlike the Robert brothers, Charles never flew again, although a balloon using hydrogen for its lift came to be called a Charlière in his honour.
Charles and Robert carried a barometer and a thermometer to measure the pressure and the temperature of the air, making this not only the first manned hydrogen balloon flight, but also the first balloon flight to provide meteorological measurements of the atmosphere above the Earth's surface.
It is reported that 400,000 spectators witnessed the launch, and that hundreds had paid one crown each to help finance the construction and receive access to a 'special enclosure' for a "close-up view" of the take-off. Among the 'special enclosure' crowd was Benjamin Franklin, the diplomatic representative of the United States of America. Also present was Joseph Montgolfier, whom Charles honoured by asking him to release the small, bright green, pilot balloon to assess the wind and weather conditions.

Famous quotes containing the words hydrogen, balloon and/or flight:
“All you of Earth are idiots!... First was your firecracker, a harmless explosive. Then your hand grenade. They begin to kill your own people a few at a time. Then the bomb. Then a larger bomb, many people are killed at one time. Then your scientists stumbled upon the atom bomb—split the atom. Then the hydrogen bomb, where you actually explode the air itself.”
—Edward D. Wood, Jr. (1922–1978)
“When I am on a stage, I am the focus of thousands of eyes and it gives me strength. I feel that something, some energy, is flowing from the audience into me. I actually feel stronger because of these waves. Now when the play’s done, the eyes taken away, I feel just as if a circuit’s been broken. The power is switched off. I feel all gone and empty inside of me—like a balloon that’s been pricked and the air’s let out.”
—Lynn Fontanne (1887–1983)
“Its shrill scream seems yet to linger in its throat, and the roar of the sea in its wings. There is the tyranny of Jove in its claws, and his wrath in the erectile feathers of the head and neck. It reminds me of the Argonautic expedition, and would inspire the dullest to take flight over Parnassus.”
—Henry David Thoreau (1817–1862)
