Olsen flies like a skier, swooping, climbing, and arcing high-angle turns through the air. He says he thinks of flying the same way he used to approach slalom gates—trying to preserve or even increase momentum in the turn. Especially when the air is smooth, he says, the perfect turn is possible. In the airplane, that means extra g-forces, and when he banks around the deep belly of a cirque, the compression adds more punch to the swooping arc. With his left hand he operates a silver iPod, which is patched into our headphones. He tries one song and then another as we buzz serrated peaks and thread rocky notches in search of cloud-free zones and clear glacial shelves to land on. We’ve got more skiing to do.
