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.
Frederick Walker Baldwin
Baldwin used his engineering skills to help build the "Silver Dart" plus several other experimental aircraft. On March 12, 1908 at Lake Keuka, New York he became the first Canadian, and either the third or fourth North American, to pilot an airplane. William Whitney Christmas claimed to have first flown his aircraft on various dates from September 1907 to March 1908 near Fairfax, Virginia. The first two successful pilots were, of course, the famous Wright brothers, but it seems unlikely that it will ever be firmly established whether Christmas or Baldwin was the so-called "Third Man."
