SkyVenture is a vertical wind tunnel that safely and realistically simulates the experience of jumping out of a plane. Developed for training purposes, the tunnels feature wall-to-wall airflow that makes it easy for visitors to do flips and acrobatics while "flying." One enthusiast, writing in Kevin Kelly's Cool Tools
newsletter, said she had "one of the most fun experiences of my life at a skydiving skills camp at SkyVenture." With locations throughout the U.S., in London, Abu Dhabi, and Malaysia, as well as with 15 other worldwide sites in the works, thrill-seeking acrophobics can start planning.
