Boeing has delivered the first 787-9 Dreamliner assembled at its North Charleston, S.C., facility to United Airlines. The airplane also marks a milestone for the 787 program as the 250th Dreamliner to be delivered. In the first quarter of 2013, Boeing South Carolina teammates began fabrication, assembly and integration of the aft and mid fuselage sections for the first Boeing 787-9 and delivered them to Everett Final Assembly. In November 2014, work began on the first South Carolina-built 787-9 when the first aft and mid sections were delivered to Boeing South Carolina Final Assembly. The airplane rolled out to the flight line in January 2015 and completed its first flight last month. This is the fourth 787-9 for United Airlines, in addition to the 12 787-8s the airline already has in service.
