manned balloon

A manned balloon is a type of aircraft that uses a large, fabric-covered envelope filled with a lighter-than-air gas, such as helium or hot air, to lift a cabin with passengers or equipment. Unlike airplanes, it has no engines for propulsion and relies on the natural buoyancy of the gas. The pilot or passengers can control altitude by adjusting the temperature or gas volume but cannot steer direction effectively. Manned balloons are used for recreation, scientific research, and aerial observation, offering a quiet, stable, and scenic way to travel or study from the air.
