Freefall speeds for skydivers falling “belly to earth” (the standard arched position) range from 110 to 130 miles per hour (180 to 210 km per hour). The fall rate is determined by the jumpsuit the skydiver wears and the way in which the suit conforms to the body during the freefall (a looser suit offers more resistance to the air and slows the fall) and by the diver’s body configuration relative to the ground. The length of the freefall (the time between exiting the aircraft and deploying the parachute) is dependent upon such factors as exit altitude, opening altitude, and fall rate. Typical jump altitudes in modern times for experienced skydivers range from 7,500 to 15,000 feet (2,300 to 4,600 metres) above ground level, yielding a freefall time of between 40 and 85 seconds.

At events such as the annual World Free Fall Convention in Quincy, Illinois, however, parachutists are afforded the opportunity to jump from such diverse craft as hot-air balloons, helicopters, and a Boeing 727.

The sport traces its beginnings to the descents made from a hot-air balloon by the French aeronaut André-Jacques Garnerin in 1797, but modern skydiving is usually performed from a propeller-driven airplane. Skydiving, also called parachuting, use of a parachute-for either recreational or competitive purposes-to slow a diver’s descent to the ground after jumping from an airplane or other high place.
