A balloon may be free, moving with the wind, or tethered to a fixed point. It is distinct from an airship, which is a powered aerostat that can propel itself through the air in a controlled manner. Ballute – (a portmanteau of balloon and parachute) is a parachute-like braking device optimized for use at high altitudes and supersonic velocities
Tethered balloons and, to a lesser extent, kites were developed for military and meteorological observation, however the use of kites has remained largely recreational. Free-flying ballooning using coal gas (which has about half the lifting effect of hydrogen) became a popular sport.
German observation balloon launching at Équancourt in the Somme (22 September 1916) German war plane brings down a tethered kite balloon (1918) World War I was the high point for the military use of observation balloons, which were extensively deployed by both sides. The British, despite their experience in late 1800s Africa, were behind ...
The air-filled red balloon acts as a simple ballonet inside the outer balloon, which is filled with lifting gas. A ballonet is an air bag inside the outer envelope of an airship which, when inflated, reduces the volume available for the lifting gas, making it more dense.
A tethered helium balloon gives the public rides to 500 feet (150 m) above the city of Bristol, England. The inset shows detail of the gondola. As an alternative to free flight, a balloon may be tethered to allow reliable take off and landing at the same location. Some of the earliest balloon flights were tethered for safety, and since then ...
Drachen kite balloon, showing its characteristic shape. A kite balloon is a tethered balloon which is shaped to help make it stable in low and moderate winds and to increase its lift. It typically comprises a streamlined envelope with stabilising features and a harness or yoke connecting it to the main tether and a second harness connected to ...
