The Full Story

thin copper spheres could not sustain ambient air pressure, and further experiments proved that his idea was impossible. Using a vacuum to create lift is called a vacuum airship, but it is still impossible to build with the materials available today. In 1709, Bartolomeu de Gusmão approached King John V of Portugal and claimed to have discovered a way for airborne flight. Due to the King's illness, Gusmão's experiment was rescheduled from its initial 24 June 1709, date to 8 August. The experiment was carried out in front of the king and other nobles in the Casa da India yard, but the paper ship or device burned down before it could take flight. === Balloons === In France, five aviation firsts were accomplished between 4 June and 1 December 1783: On 4 June, a crowd gathered in Annonay, France, to witness the unmanned hot air balloon display by the Montgolfier brothers. Their 500-pound balloon ascended to nearly 3,000 feet and traveled over a mile and a half. It stayed in the air for ten minutes before tipping over and catching fire. On 27 August, Jacques Charles and the Robert brothers launched the first unmanned hydrogen balloon from Paris' Champ de Mars. It landed almost an hour later in Gonesse, where terrified farmers mistook it for a monster and destroyed it. On 19 October, in front of 2,000 spectators, Jean-François Pilâtre de Rozier and the Marquis d'Arlandes boarded the Montgolfier aircraft as the first people. Later that day, Giroud de Villette, another pilot, took to the skies much higher. On 21 November, the Montgolfiers launched the first free flight with human passengers. King Louis XVI had originally decreed that condemned criminals would be the first pilots, but Jean-François Pilâtre de Rozier, along with the Marquis François d'Arlandes, successfully petitioned for the honour. They drifted 8 km (5.0 mi) in a balloon powered by a wood fire. On 1 December, Jacques Charles and the Nicolas-Louis Robert launched their manned hydrogen balloon from the Jardin des Tuileries in Paris, as a crowd of 400,000 witnessed. They ascended to a height of about 1,800 feet (550 m)[15] and landed at sunset in Nesles-la-Vallée after a flight of 2 hours and 5 minutes, covering 36 km. After Robert alighted, Charles decided to ascend alone. This time he ascended rapidly to an altitude of about 9,800 feet (3,000 m), where he saw the sun again, suffered extreme pain in his ears, and never flew again. Ballooning became a major interest in Europe in the late 18th century, providing the first detailed understanding of the relationship between altitude and the atmosphere. Non-steerable balloons were employed during the American Civil War by the Union Army Balloon Corps. The young Ferdinand von Zeppelin first flew as a balloon passenger with the Union Army of the Potomac in 1863. In the early 1900s, ballooning was a popular sport in Britain. These privately owned balloons usually used coal gas as the lifting gas. This has half the lifting power of hydrogen
