ADRSPACH, Czech Republic  Exactly a decade has passed since a man called Oxygen first hurled himself across Amerika. Known for his jumping ability, Oxygen, a lanky Czech, catapulted to legend status by leaping a nearly 10-foot-wide abyss separating two 100-foot sandstone spires.

Today, Petr Kops, 21, is wearing Oxygen’s hand-me-down pants.

“I did not know Oxygen personally, but my sister did,” Kops said. “I wear his trousers for good luck.”

Minutes later, Kops was standing at the edge of a 70-foot chasm called Broken Bones. He announced that he was about to damage his ankle. Then he jumped.

While it may seem suicidal, leaping across a gaping crevasse is actually an extreme sport that is gaining in popularity.
