HURRICANE FACTORY Prague is the only wind tunnel in the Czech Republic. It is a place where you can find out what it's like to fly and to float in the air and to feel the force of a hurricane. In a glass flight chamber, 4.3 metres in diameter and with an incredible total height of 14 m, air flows at a speed of up to 270 km/hour, which is the speed of a real hurricane. But you will be flying at a safe height and under the constant supervision of an experienced instructor. All physically able people from the age of five can fly in the wind tunnel.
