November 2010: Dream Lines
The Jump: Jokke Sommer releases a series of videos called "Dream Lines" filmed on mountains around the world, featuring harrowing "proximity flying" just feet off the ground — similar to Jean-Albert's earlier jumps, but with more complex twists and turns.
Why It Matters: The death-defying style — and the closeness of the terrain — "made the best YouTube videos," says Potter. But the popularity of proximity jumping also led the sport to claim more lives per year than ever. "A gust of wind or a thermal can destroy you," says Potter.
