BASE jumping is a sport involving the use of a parachute or the sequenced use of a wingsuit and parachute to jump from fixed objects–with the parachute unopened at the jump (else see paragliding). “BASE” is an apronym that stands for the four categories of fixed objects from which one can jump just like Building, Antenna ,Span ,Earth etc.I have never do this kind of sports, it’s too dangerous. What should I do if the wingsuit cannot work after I jumped ??
