n.— «Boeing’s supplier partners did not install many of the electronic and hydraulic systems into their respective fuselage sections as planned. Boeing is shifting workers—known as “travelers” in airplane production argot—from other airplane programs, such as the 777 Jetliner, to make up for the unfinished work. That is sure to boost overtime pay, push workers harder, and create havoc as employees frantically try to catch up on the unfinished work.» —“Crunch Time for Boeing” by Stanley Holmes BusinessWeek May 22, 2007.
