A hot air balloon in flight In 1999, Bertrand Piccard and Brian Jones achieved the first non-stop balloon circumnavigation in Breitling Orbiter 3.

In aeronautics, a balloon is an unpowered aerostat, which remains aloft or floats due to its buoyancy. It may use hot air as a lifting gas, or it may use gas that is not air like hydrogen or helium. 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.
