ベースジャンピング
As compared to skydiving from an airplane, BASE jumping involves jumping from a "fixed object" such as a cliff. BASE jumping in its modern form has existed since at least 1978. But it was not until 1997 that Patrick de Gayardon made some of the first-ever wingsuit BASE jumps combining the two disciplines. Compared to normal BASE jumping, wingsuit BASE jumping allows pilots to fly far away from the cliffs they jumped from, and drastically increase their freefall time before deploying a parachute. Since 2003, many BASE jumpers have started using wingsuits, giving birth to wingsuit BASE.
