flying K
n.— «This is skiing’s equivalent of drag racing and, unlike in slalom, there are no gates or turns. Speed skiers just point the ski tips straight down a hill that is so steep it is almost freefall. Also known as the “flying K,” because speeds are measured over the distance of a 10th of a kilometre, the figures resemble those of Formula One: 0-60mph in 3sec, 120mph in less than 6sec and a world record that would even make Klammer’s eyes water—251.4kph or about 156mph.» —“I’m going downhill fast—at 94mph” by Graham Duffill Times (London, United Kingdom) Feb. 3, 2008.
