Parachuting, also known as skydiving, is the action of performing acrobatics during freefall, followed by deployment of a parachute. A typical jump involves individuals jumping out of an aircraft (usually an airplane, but sometimes a helicopter or even the gondola of a balloon), at approximately 4,000 meters (around 13,000 feet) altitude, and free-falling for a period of time (about a minute)[1] before activating a parachute to slow the landing down to safe speeds (about 5 to 7 minutes). Canopy Piloting (also known as swooping) encompasses several disciplines, all involving the flight of a skydiving parachute either at high altitude or close to the ground. Freeflying is a skydiving discipline which began in 1990 when Olav Zipser began experimenting with non-traditional forms of body flight. Zipser (FreeFly Clown No.1) formed the Freefly Clowns as a two person competitive team with Mike Vail in 1992, and was joined by Omar Alhegelan, Charles Bryan, and Stefania Martinengo in 1994. BASE jumping, also sometimes written as B.A.S.E jumping, is an activity that employs an initially packed parachute to jump from fixed objects, as with paragliding. "B.A.S.E." is an acronym that stands for four categories of fixed objects from which one can jump: buildings, antennae, spans (bridge), and earth (cliff).
