Human Flight Athlete Alexander Polli wingsuit diving in New Zealand, Switzerland, and Norway. This is proximity flying with a wingsuit and proximity flying in tracking gear (tracksuit) without a wingsuit; tracking gear consists of a jacket and pants that inflate with air, which then increases push force when you move your body through the air.
Proximity flying with a wingsuit is recommended only for very trained athletes and is considered a very dangerous sport. Proximity flying in tracking gear leaves even less margin for error and requires a more specific choice of flyable lines—if you get too deep, you don’t have wings to help you get out. Enjoy one of his older flights and the crazy cave hole and see why he was famous.
