US aerospace giant Boeing said Thursday it was further delaying the launch of its 787 Dreamliner because of disruptions from a machinists strike and production problems. Boeing moved the first flight of the commercial plane into the second quarter of 2009 and the first delivery into the first quarter of 2010. The initial flight had been scheduled in the fourth quarter of 2008 and deliveries were to begin in the third quarter of 2009. "The new schedule reflects the impact of disruption caused by the recent machinists' strike along with the requirement to replace certain fasteners in early production airplanes," the company said in a statement.
