Hot air ballooning is an aerial activity that involves flying in a large balloon filled with heated air. The balloon consists of a fabric envelope, which holds the hot air, and a basket that carries passengers. The air inside the envelope is heated using a burner, allowing the balloon to rise. As the air cools, the balloon descends. Pilots control the altitude by adjusting the temperature of the air inside the envelope. Hot air balloons are often used for recreational flights, offering stunning views of the landscape below. They are also popular for special events and festivals, attracting enthusiasts worldwide.
