History of transport balloons filled with hot air were used in the first half of the 19th century and saw considerable action in several mid-century wars, most notably the American Civil War, where balloons provided observation during the Siege of Petersburg. Apart from some scattered reference in ancient and medieval records, resting on slender evidence and in need of interpretation, the earliest clearly verifiable human flight took place in Paris in 1783, when Jean-François Pilâtre de Rozier and François Laurent d'Arlandes went in a hot air balloon invented by the Montgolfier brothers. The Wright brothers made the first sustained, controlled and powered heavier-than-air
Hot air balloon an open flame near the gas. All modern Roziere balloons now use helium as a lifting gas. Solar balloons are hot air balloons that use just solar energy captured by a dark envelope to heat the air inside. Hot air balloon can be steered to a limited degree by changing the altitude of the flight. Wind in the northern hemisphere tends to turn right due to coriolis effect as the altitude increases. To help ensure the safety of pilot and passengers, a hot air balloon may carry several pieces of safety equipment. To relight the burner if the pilot light
