The man who died, 27-year-old Denis Burakov, was with friends at the Dombai ski resort, where they frequently went snowboarding, on Jan. 3 when he decided to take a ride in a zorb being operated next to a beginners' slope. His friend Vladimir Shcherbakov joined him.
An eight-minute video taken on Burakov's phone by one of his friends shows the two men being fitted into harnesses inside the zorb, which consists of two polyurethane balls with a layer of air between them. The zorb is then released to roll down the hill, the two men spinning inside.
But the zorb bounces off of the intended path, and a man waiting for it at the bottom of the hill tries in vain to catch the ball before it pops over a rocky ledge and disappears down a gorge below Mount Mussa-Achitara.
The person filming the video is heard swearing and asking "What's down there?" The answer from someone off camera: "It's a catastrophe down there."
The Emergencies Ministry said both men were ejected from the zorb as it tumbled and they landed on the snow about 10 meters (30 feet) apart after having rolled about 1.5 kilometers (a mile). Still conscious and able to stand, they were rescued by two skiers, who then pulled both men up to the top of the hill. Burakov suffered serious spinal injuries and died on the way to the hospital. Shcherbakov suffered a concussion and other injuries and remains hospitalized.
The accident prompted the emergencies minister to demand that Russia address its lax enforcement of safety rules for winter sports, citing a series of accidents over the January holidays. Vladimir Puchkov said during a televised meeting with officials in charge of rescue services across the country that they should take extra measures to ensure safety, in particular at Russia's ski slopes.
