Although most of the airborne forces of the world still use round parachutes, some specialized military free-fall units use ram-air airfoils, which provide control of speed and direction, as their primary means of infiltration.
Airborne Systems has recently completed a test drop of its Gigafly modified ram-air parachute with an 8165-kg payload from 17,500 ft above mean sea level.
