gas ballooning

Gas ballooning is a form of air travel where a large balloon is filled with a lighter-than-air gas, such as helium or hot air, to achieve lift. The balloon's envelope expands or contracts based on temperature and altitude changes, allowing controlled ascent and descent. The pilot navigates by adjusting the altitude and catching wind currents at different levels. This method provides a peaceful, scenic experience and requires careful management of gas and weather conditions for safety. Gas ballooning has been used historically for exploration, recreation, and scientific research.
