The pair attempted their wingsuit flight on Saturday around dusk -- a time that National Geographic says many athletes choose for BASE jumping, which is illegal in all of America's national parks. They were found Sunday by a search and rescue helicopter.
BASE jumping, we'll remind you, is the sport of parachuting from a fixed point, such as a cliff or structure. The acronym stands for the leaping-off point: a building, antenna, span or the Earth. It has also gained a reputation for being deadly. Since the early 1980s, 256 people have died while taking part in the sport, according to Blinc magazine.
