From early times people wanted to fly. In 1783 a group of inventors first successfully flew a hot-air balloon. Since that time people have learnt a lot about this kind of sport and break many records in balloons. In 1961 a balloon with men on board flew higher than 35 kilometres. In 1999 the first trip around the world in a balloon was made. The trip lasted 19 days. Balloon travellers say that absolutely feel the excitement of a bird's-eye view. And it is a very comfortable trip because the balloon moves with the wind and passengers feel free.
