context_page_description: A vertical wind tunnel is a wind tunnel which moves air up in a vertical column. Unlike standard wind tunnels which have test sections that are oriented horizontally, as experienced in level flight, a vertical orientation enables gravity to be countered by drag instead of lift, as experienced in an aircraft spin or by a skydiver at terminal velocity.
  Although vertical wind tunnels have been built for aerodynamic research, the most high-profile are those used as recreational wind tunnels, frequently advertised as indoor skydiving or bodyflight, which have also become a popular training tool for skydivers.
