Quad (figure skating)
A quad, or quadruple, is a figure skating jump with at least three but less than four revolutions. Most quadruple jumps have 3 1/2 revolutions; the quadruple Axel has 4 1/2 revolutions, although no figure skater to date has completed this jump in competition. The quadruple toe loop and quadruple Salchow are the two most commonly skated in the discipline. Quadruple jumps have become increasingly common among World and Olympic level men's single skaters, to the point that not having one in a program has come to be seen as a severe handicap. The first person to land a ratified quadruple jump in competition was Canadian Kurt Browning in 1988. In 2002, Miki Ando became the first woman to do so, and she remains one of only two women to have landed a ratified quadruple jump in competition.
Bobby Brown (freestyle skier)
Brown was the first to execute multiple variations of a triple flip or triple cork at a training session in Squaw Valley, California. He gained notoriety after winning both the SlopeStyle and Big Air events at Winter X Games XIV, registering a perfect score of 100 in the latter. Brown was the first person ever to have landed a Switch Double Misty 1440. He was one of the first skiers ever to have landed a Triple Cork 1440.
