When you arrive at the Chicago Lincoln Park indoor skydiving location, get started by putting on your provided gear and going through a specialized training session from a flight instructor. Learn how to safely float in a 1,400-horsepower vertical wind tunnel that generates a wall-to-wall cushion of air, commonly used by professional skydivers. Experience the thrill of skydiving without having to hurl yourself from an airplane, and no experience is necessary. Once inside the enclosed space of the flight chamber, a tunnel operator slowly increases the wind speed until you and your instructor are airborne. Feel your adrenaline pumping as you 'free fall' at wind speeds reaching 180 mph (290 kph). The stable wind flow keeps you from falling off the column of air, and your instructor is on hand at all times to guide you. The first-time flyer experience takes about 75min. Each session includes up to 12 people, but fly one-on-one with your instructor in the wind tunnel twice for 60 seconds.
