This ultra–extreme sport is called wingsuit. The idea of flying in special suits was borrowed from flying squirrels. For a long time, attempts to design a flight suit ended tragically. Only about twenty years ago, a modern reliable wingsuit form was developed. The suit was equipped with three wings (instead of two, as in earlier versions), equipped with two layers of fabric capable of being filled with incoming airflow. One of the most difficult disciplines of parachuting. Not everyone has the ability to plan on the surface.
