The first untethered manned hot air balloon flight in the world was performed in Paris, France, by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783, [1] in a balloon created by the Montgolfier brothers.

Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same way that a rocket works.
Geostationary balloon satellites (GBS) are proposed high-altitude balloons that would float in the mid-stratosphere (60,000 to 70,000 feet (18 to 21 km) above sea level) at a fixed point over the Earth's surface and thereby act as an atmospheric satellite. At those altitudes, air density is around 1/15 to 1/20 [37] of what it is at sea level ...
