A wingsuit is a remarkably simple invention that allows the wearer to soar through the air like a flying squirrel, arms and legs outstretched, floating on a pillowy cushion of his own sheer insanity. Of the many ways human beings have devised to get themselves killed, it’s one of the most awe-inspiring and effective. During 2016, the deadliest year ever for wingsuiters, there were more than 30 fatalities. That number is due mostly to the sport’s popularity. As former Navy fighter pilot and BASE jumping aficionado Richard Webb told National Geographic, “Right now, wingsuit BASE jumping is, globally, the hottest thing going for the impressionable, 18- to 35-year-old single-male demographic.”
