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: The acronym BASE was coined by film-maker Carl Boenish, his wife Jean Boenish, Phil Smith, and Phil Mayfield. Carl was the real catalyst behind modern BASE jumping, and in 1978 filmed the first BASE jumps (from El Capitan, in Yosemite National Park) to be made using ram-air parachutes and the freefall tracking technique. While BASE jumps had been made prior to that time, the El Capitan activity was the effective birth of what is now called BASE jumping. BASE jumping is significantly more dangerous than similar sports such as skydiving from aircraft, and is currently regarded by many as a fringe extreme sport or stunt. During the early eighties, nearly all BASE jumps were made using standard skydiving equipment, including two parachutes (main and reserve), and deployment components. Later on, specialized equipment and techniques were developed that were designed specifically for the unique needs of BASE jumping. This screensaver is free, and contains no spyware or virus.
