<p>209.105.200.134: </p> <hr /> <div>The '''Montgolfier brothers''', [[Joseph Montgolfier|Joseph]] and [[Etienne Montgolfier]], were sons of a paper manufacturer at [[Annonay]], south of [[Lyon]], [[France]]. When playing with inverted paper bags over open fire they found that the bags rose to the ceiling.<br /> <br /> On June 5, 1783, they sent up at Annonay, near [[Lyon]], a large linen bag inflated with hot air; its flight covered more than a mile and lasted 10 min. In the same year a Montgolfier balloon sailed over Paris in the first manned free balloon flight demonstration made at the royal court in [[Versailles]] in August, [[1783]]. <br /> <br /> Only one of the brothers ever flew himself in a balloon, and only once.<br /> <br /> The first manned ascent was made on [[November 21]], [[1783]], by [[Pilâtre de Rozier]] and [[Marquis d'Arlandes]].<br /> <br /> [[Hot air balloon]]s soon were surpassed by gas balloons and did not return until the [[1960s]] when propane gas became available as a practical fuel.</div>
