Figure skating jumps
Jumps are referred to by how many times the skater turns in the air. One revolution (one and a half for the Axel) is a "single" jump. Two revolutions (two and a half for the Axel) is a "double" jump. Three revolutions (three and a half for the Axel) is a "triple" jump. Four revolutions (four and a half for the Axel, although this has never been done in competition) is a "quadruple" or "quad" jump. The first triple jump landed in competition was a loop jump. It was landed by Dick Button in 1952. The first quadruple jump landed in competition was a toe loop jump. It was landed by Kurt Browning in 1988. Currently, men in world-class competition usually attempt a full set of triples and sometimes one or two quadruple jumps in their free skating programs. Triple Axels are rare for ladies, and quadruple jump attempts even more so.
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."
