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.
Langley Air Force Base Langley Field was named after Samuel Pierpont Langley, an aerodynamic pioneer and a former Secretary of the Smithsonian Institution.  Langley began aerodynamic experiments in 1887 and formed a basis for practical pioneer aviation. He built and saw the first steam model airplane in 1896 and the first gasoline model in 1903.  Both planes were believed to be capable of flight.  He also built the first man-carrying gasoline airplane in 1903, which failed to fly on its first attempt and broke apart and crashed on its second. It was, after major modification eleven years later, flown "successfully" by Glenn Curtiss for a little over 3 seconds, traveling 150 feet through the air in 1914.[6]  Langley Field was the first Air Service base built especially for air power, is the oldest continually active air force base in the world, and is the oldest airfield in Virginia.
