  • 1812
  • 1819
    • 6 July – Sophie Blanchard launches fireworks from her balloon in flight during an exhibition at the Tivoli Gardens in Paris. The fireworks ignite the gas in the balloon, which crashes on the roof of a house. She falls to her death, becoming the first woman to die in an aviation accident.[9]
  • 1824
    • Englishman Thomas Harris dies when his balloon crashes near Carshalton. His female passenger survives. The exact cause is not determined but is apparently due to a valve Harris has designed to release gas from the balloon becoming stuck open. Despite dropping all ballast Harris is unable to stop a precipitous plunge.[10][11]
  • 1836
  • 1837
    • Robert Cocking jumps from a balloon piloted by Charles Green at a height of 2,000 m (6,600 ft) to demonstrate a parachute of his own design, and is killed in the attempt.[15]
  • 1838
    • 4 September – Charles Green, George Rush, and Edward Spencer ascend to an altitude of 19,335 feet (5,893 meters) over England in the Great Balloon of Nassau before landing at Thaxted.
    • 10 September – Green and Rush ascend to a world record altitude of 27,146 feet (8,274 meters) over England in the Great Balloon of Nassau, reaching speeds of 80 to 100 mph (130 to 160 km/h) during the flight.
  • 1839
    • The American John Wise introduces the ripping panel which is still used today. The panel solved the problem of the balloon dragging along the ground at landing and needing to be stopped with the help of anchors.[16]
    • Charles Green and the astronomer Spencer Rush ascend to 7,900 m (25,900 ft) in a free balloon.

  • 1840
  • 1841
    • An ironsmith kalfa (journeyman) named Manojlo who "came to Belgrade from Vojvodina"[18] attempts to fly an ornithopter. Forbidden to take off from the belfry of St. Michael's Cathedral by the authorities, he clandestinely climbs to the rooftop of the Đumrukhana (Import Tax Head Office) and jumps off, landing in a heap of snow and surviving.[19]
  • 1842
    • November – English engineer William Samuel Henson makes the first complete drawing of a power-driven aeroplane with steam-engine drive. The patent follows the works of Cayley. The English House of Commons rejects the motion for the formation of an "Aerial Transport Company" with great laughter.
  • 1843
  • 1845
    • William Samuel Henson and John Stringfellow build a steam-powered model aircraft, with a wingspan of 10 ft (3.0 m).

  • 1848
  • 1849
    • 12–25 July – While blockading Venice, the Austrians launch unmanned incendiary balloons equipped with explosive charges from land and as well as from the steamship SMS Vulcano in an attempt to bombard Venice. Although the experiment is mostly unsuccessful, it is both the first use of balloons for bombardment and the first time a warship makes offensive use of an aerial device.[21]
    • 2–3 September – French balloonist Francisque Arban makes the first (and until 1924 only) balloon flight over the Alps, flying a hydrogen balloon from Marseille to Turin.
    • 7 October – Francisque Arban takes off from Barcelona, but his balloon is blown over the Mediterranean Sea and is lost.
    • Sir George Cayley launches a 10-year-old boy in a small glider being towed by a team of people running down a hill. This is the first known flight by a person in a heavier-than-air machine.[22]
  • 1852
    • 24 September – French engineer Henri Giffard flies 27 km (17 mi) from the Paris Hippodrome to Trappes in a steam-powered dirigible,[23] reaching a speed of about 10 km/h (6.2 mph).
  • 1853
    • Late June or early July – Sir George Cayley's coachman successfully flies a glider, designed by his employer, some proportion of the distance across Brompton Dale in Yorkshire, becoming the world's first adult aeroplane pilot.[24] Unimpressed with this honour, the coachman promptly resigns his employment.
  • 1856
    • December – French Captain Jean Marie Le Bris is towed into the air in his Artificial Albatross glider, flying 600 ft (180 m).

  • 1861
  • 1862
  • 1863

    • Outbreak of the Paraguayan War between the Alliance of Argentina, Brazil and Uruguay against Paraguay. The Alliance forces made much use of balloon reconnaissance over the next six years.
    • English philosopher-scientist Matthew Piers Watt Boulton of the UK writes his short paper, On Aerial Locomotion, detailing several inventions, including that of the aileron almost as an afterthought (he later patents them in 1868). Boulton's inspiration has been attributed to French Count Ferdinand Charles Honore Phillipe d'Esterno, whose detailed analysis of flapping and soaring bird flight, Du Vol des Oiseaux (On the flight of birds) was published as a pamphlet in 1864.[34]
  • 1865
    • Solomon Andrews flies a dirigible twice over New York City.
    • German experimenter Paul Haenlein takes out a patent for the "Earliest Known Airship With a Semi-rigid Frame," envisioned to have a coal-gas-burning engine which draws its fuel from the craft's envelope, which is filled with coal gas. He later will construct the craft in Germany.[35]
    • Jules Verne describes in his novel The Journey to the Moon the launch of a rocket from Florida, from which many years later American space flights actually will start.
    • The Frenchman Le Comte Ferdinand Charles Honore Phillipe d'Esterno writes in his book About the Flight of Birds, "Gliding seems to be characteristic for heavy birds; there are no odds which are stacked against that humans can not do the same at fair wind." He had earlier published the 1864 pamphlet Du Vol des Oiseaux (On the flight of birds).[34]
    • French artist and farmer Louis Pierre Mouillard makes a tentative gliding flight. After years of studies of bird flight he publishes his book L'Empire de l'Air in 1881. He thinks that imitation of gliding and soaring flight of birds is possible, but not the imitation of the flapping of wings.
    • 20 September – Jacob Brodbeck, in his coil-spring-driven airship, flies 100 feet before crashing in a field near Luckenbach, Texas, USA.[36]
  • 1866
    • First South American military balloon reconnaissance ascent. On 6 July, Lieutenant Colonel Roberto A. Chodasiewicz, an Argentine Army military engineer, makes the first South American military observation ascent, manning a Brazilian Army's captive ballon over Paraguayan troops, during the Paraguayan War.

  • 1897
    • 11 June – Salomon Andrée, Nils Strindberg, and Knut Frænkel attempt an expedition to the North Pole by free balloon from Spitsbergen. They crash within three days but manage to survive for several months in the pack ice. Their remains are discovered in 1930 on White Island. It was possible to develop the preserved film material.[75]
    • 12 June – Friedrich Hermann Wölfert and his mechanic are killed when their petrol-powered airship catches fire during a demonstration at the Tempelhof field.[76]
    • 14 October – Clément Ader later asserts that on this date he made a 300 m (980 ft) flight in his steam-powered uncontrolled Avion III also referred to as Aquilon or the Éole III. His claim is disputed. The French Army is not impressed and withdraws funding.
