Skydiving has strongly developed over the last decades. The equipment has become safer and safer, fabrics and manufacturing techniques have consistently improved. By using state of the art WingSuits, skydivers have been able to substantially extend freefall flying times, which makes their sport even more attractive. WingSuits consist of small ‘wings’ that run between the arms and hips of the flyers. Another ‘wing’ attaches both feet together. The ‘wings’ inflate during freefall and diver and suit melt together into one aerodynamic package similar to the wing of an airplane.
