BASE Jumping: is very extreme activity that includes a parachute (can be used both parachute and wingsuit) to jump from fixed objects, with unopened parachute like skydiving. The acronym “B.A.S.E.” stands for: Building, Antenna, Span, Earth – four categories of objects from which B.A.S.E. jumper can jump.
BASE numbers are awarded to those who have made at least one jump from each of the four categories (buildings, antennas, spans and earth).
BASE jumping grew out of skydiving. BASE jumps are generally made from much lower altitudes than skydives, and a BASE jump takes place close to the object serving as the jump platform. Because BASE jumps generally entail slower airspeeds than typical skydives (due to the limited altitude), a BASE jumper does not always reach terminal velocity. Because higher airspeeds enable jumpers more aerodynamic control of their bodies, as well as more positive and quick parachute openings, the longer the delay, the better. BASE jumping is significantly more dangerous than similar sports such as skydiving from aircraft.
