Man dies after giant inflatable ball he's riding in rolls off cliff

Here's terrible proof that extreme sports can be extremely dangerous. One man was killed and another injured when the giant inflatable Zorb ball they were strapped inside sped down a mountain before veering off course and over a cliff. The giant ball rolled harmlessly down a Russian ski-resort mountain before it lurched off its path, with organizers frantically chasing it. The plastic ball traveled for less than one mile down the mountain, hitting several rocks on the way. Denis Burakov, 27, died when he broke his neck and spine, while Vladimir Shcherbov, 33, was treated at a local hospital for a concussion and multiple cuts and bruises to his body. [Source]
