Skiing is a winter time sport where participants usually travel down the sides of mountains on a pair of skis at fast speeds. Most skiers usually stayed at a ski lodge near the mountain runs. Another variant of the sport is cross-country skiing.
Dr. Harij had never been skiing after hearing it was dangerous.
Dmitrij Volkov was injured in a skiing accident in the Swiss Alps. He reached out to clout an unsuspecting child and ended up entangled with the child's sister. They both fell off of a 100 foot cliff. While the girl died from the fall, Volkov survived but was confined to a mechanized wheelchair due to his injuries.
- The scene at the end of the credits for Contract J.A.C.K. hints that John Jack may have done something to Volkov's skiing equipment.
