<P> Since the animals survived, the king allowed flights with humans . Again in collaboration with Réveillon, Étienne built a 60,000 - cubic - foot (1,700 m) balloon for the purpose of making flights with humans.It was about seventy - five feet (23 m) tall and about fifty feet (15 m) in diameter . Réveillon supplied rich decorative touches of gold figures on a deep blue background, including fleur - de-lis, signs of the zodiac, and suns with Louis XVI's face in the center interlaced with the royal monogram in the central section . Red and blue drapery and golden eagles were at the base of the balloon . Étienne Montgolfier was the first human to lift off the Earth, making a tethered test flight from the yard of the Réveillon workshop in the Faubourg Saint - Antoine, most likely on October 15, 1783 . A little while later on that same day, physicist Pilâtre de Rozier became the second to ascend into the air, to an altitude of 80 feet (24 m), which was the length of the tether . </P> <P> On 21 November 1783, the first free flight by humans was made by Pilâtre de Rozier, together with an army officer, the marquis d'Arlandes . The flight began from the grounds of the Château de la Muette close to the Bois de Boulogne park in the western outskirts of Paris . They flew about 3,000 feet (910 m) above Paris for a distance of nine kilometers . After 25 minutes, the balloon landed between the windmills, outside the city ramparts, on the Butte - aux - Cailles . Enough fuel remained on board at the end of the flight to have allowed the balloon to fly four to five times as far . However, burning embers from the fire were scorching the balloon fabric and had to be daubed out with sponges . As it appeared it could destroy the balloon, Pilâtre took off his coat to stop the fire . </P> <P> The early flights made a sensation . Numerous engravings commemorated the events . Chairs were designed with balloon backs, and mantel clocks were produced in enamel and gilt - bronze replicas set with a dial in the balloon . One could buy crockery decorated with naive pictures of balloons . </P> <P> In December 1783, father Pierre Montgolfier was elevated to the nobility and the hereditary appellation of de Montgolfier by King Louis XVI of France . </P>
