In freestyle skiing, Jeret Peterson and Ryan St. Onge take their first jumps in the qualifying round of men's aerials. In Torino, the U.S. failed to win a medal in men's aerials for the first time since the event made its debut on the Olympic program at the Lillehammer Games in 1994. In 2010, the U.S. brings renewed medal hopes to Vancouver on the skis of Ryan St. Onge and Jeret 'Speedy' Peterson. The 26-year-old St. Onge, a member of the U.S. freestyle team since age 14, won gold at the 2009 World Championships, making him the first American aerials world champion since Eric Bergoust in 1999. Idaho native Peterson (a.k.a. "Speedy"), known for his signature quintuple-twisting triple flip known as the "Hurricane," is making his third Olympic appearance after placing third in the World Cup aerials standings in 2008-09.Rounding out the aerials squad will be Olympic rookies Matt DePeters and Dylan Ferguson. Neither are expected to contend for a medal.
