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.
Bryan Allen (hang glider)
Bryan Lewis Allen (born October 13, 1952) is an American self-taught hang glider pilot and bicyclist. He achieved fame when he piloted (and provided the human power for) the two aircraft that won the first two Kremer prizes for human-powered flight, the "Gossamer Condor" (1977; the first human-powered aircraft to fly and meet specified criteria) and "Gossamer Albatross" (1979; the first human-powered aircraft to cross the English Channel). He later set world distance and duration records in a small pedal-powered blimp named "White Dwarf."
