The term "Glitch" was first used to describe rocket malfunctions during the Space Race of the 1950's
Some reference books, including Random House's American Slang, claim that the term comes from the German word glitschen ("to slip") and the Yiddish word gletshn ("to slide or skid"). Either way it is a relatively new term, as on July 23, 1965, Time Magazine felt it necessary to define it in an article: "Glitches—a spaceman's word for irritating disturbances." In relation to the reference by Time Magazine, the term has been believed to enter common usage during the American Space Race of the 1950s, where it was used to describe minor faults in the rocket hardware that were difficult to pinpoint.[1][2] @Curionic
