shuttle (n.) Look up shuttle at Dictionary.com
O.E. scytel "a dart, arrow," from W.Gmc. *skutilaz (cf. O.N. skutill "harpoon"), from P.Gmc. *skut- "project" (see shoot). The weaving instrument so called (1338) from being "shot" across the threads. In some other languages, the machine takes its name from its resemblance to a boat (cf. L. navicula, Fr. navette, Ger. weberschiff). Sense of "train that runs back and forth" is first recorded 1895, from image of the weaver's instrument's back-and-forth movement over the warp; extended to aircraft 1942, to spacecraft 1969. Hence also shuttlecock (1522).
