A vertical wind tunnel (VWT) is a wind tunnel which moves air up in a vertical column. It is a recreational wind tunnel, frequently advertised as "indoor skydiving" or "bodyflight". It is also a popular training tool for skydivers.
Vertical wind tunnels enable human beings to fly in air without planes or parachutes, through the force of wind being generated vertically. Wind moves upwards at approximately 195 km/h (120 mph or 55 m/s), the terminal velocity of a falling human body belly-downwards, although this can vary from person to person. A vertical wind tunnel is frequently called 'indoor skydiving' due to the popularity of vertical wind tunnels among skydivers, who report that the sensation is extremely similar to skydiving. The human body 'floats' in midair in a vertical wind tunnel, and this is called 'bodyflight' or 'body flight'.
