Over the past few years, BASE jumping has seen quite a rise in popularity amongst adrenaline junkies and extreme athletes. The “sport” consists of climbing up any tall, fixed object, such as a building, bridge, or cliff, throwing yourself off, and using a parachute to safely float back to the ground.
More recently the activity has evolved to a degree by incorporating wingsuits into the equation. A wingsuit is a specially designed jumpsuit that incorporates fabric between the arms and body, as well as between the legs, in order to facilitate more lift. This allows the BASE jumper to glide through the air for longer distances while controlling direction as well. Eventually they still end up pulling their ripcords, but often not until after they’ve coverd sometimes significant distances at significant speeds.
The video below, which was shot in Norway, shows what happens when a couple of people in wingsuits get a bit too close for comfort with observers on the ground. The video also gives you a good sense of the speed a which they are traveling.
