Safety is a big concern in a vertical wind tunnel design. Skydiver safety involves procedures that have to be followed by the skydiver and addressed by the instructor to avoid accidents. Skydivers do not have to be worried about falling, jumping or having a fear of heights because they start flying only one foot above the ground. Their first flight is accompanied by a trained instructor holding the skydiver’s arm. Depending on the skydiver’s comfort, the airflow level may be increased; it means the skydiver would be able to go higher inside the flight chamber and challenge himself with different movements, still keeping a high level of safety.
