Paraşütün ilkesi yeterince basittir. Fransız Baloncu Jean Pierre-François Blanchard (1753-1809), sepet içindeki bir köpeği bir balondan aşağı salıp güvenle yere indirerek 1785’te ilk paraşütü kullandı. Bir insanın ilk kez başarıyla paraşütü kullanması ise 1797’de Fransız baloncu Andre-Jacques Garnerin’in (1769-1823) atlayışı ile gerçekleşti.
