How It Works

The principle is beautifully simple: hot air rises. A burner heats the air inside the envelope, and as it becomes lighter than the cooler air outside, the balloon lifts. The pilot controls altitude by firing the burner to go up and venting hot air to descend. Direction is governed entirely by the wind at different altitudes, which is why every flight traces a unique path across the landscape.

The Balloon

A modern hot air balloon consists of three parts: the envelope (the fabric shell, typically nylon, holding around 2,800 cubic metres of air), the burner (a propane-powered system producing a controlled flame), and the basket (traditionally woven from wicker, which is light, strong, and absorbs landing impact). Together they weigh about 250 kg before inflation.

Flying Conditions

Balloons fly best in calm, stable air, which is why flights happen at sunrise and occasionally at sunset. Wind speeds above 10 knots ground the flight. Rain, fog, and thunderstorms are obvious no-gos. This is why weather cancellations are part of the experience: when conditions are right, the reward is a flight so smooth you can balance a sparkling wine glass on the basket rim.
