where did the first hot air balloon land
Hot air balloon The hot air balloon is the first successful human-carrying flight technology. The first untethered manned hot air balloon flight was performed by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783, in Paris, France,[1] in a balloon created by the Montgolfier brothers.[2] The first hot-air balloon flown in the Americas was launched from the Walnut Street Jail in Philadelphia on January 9, 1793 by the French aeronaut Jean Pierre Blanchard.[3] Hot air balloons that can be propelled through the air rather than simply drifting with the wind are known as thermal airships.
History of unmanned aerial vehicles The earliest recorded use of an unmanned aerial vehicle for warfighting occurred on August 22, 1849, when the Austrians attacked the Italian city of Venice with unmanned balloons loaded with explosives known as Austrian balloons. At least some of the balloons were launched from the Austrian ship Vulcano. Although some of the balloons worked and successfully managed to bomb The Republic, others were caught in a change of wind and blown back over Austrian lines. This occurred on the first launch as the wind was not in Austria's favor on July 12, 1849[1] The Austrians had been developing this system for 66 years, since the idea was hatched in 1783. The Presse, of Vienna, Austria, stated: "Venice is to be bombarded by balloons, as the lagunes prevent the approaching of artillery. Five balloons, each measuring 5.7 meters in diameter, are in construction at Treviso. In a favorable wind the balloons will be launched and directed as near to Venice as possible, and on their being brought to vertical positions over the town, they will be fired by electro magnetism by means of a long isolated copper wire with a large galvanic battery placed on a building. The bomb falls perpendicularly, and explodes on reaching the ground."[2] Balloons do not generally meet today's definition of a UAV. Once winged aircraft had been invented, the effort to fly them unmanned for military purposes was not far behind.
